The device package allows for easy implementation by the customer. Typical applications include motor control, load detection and management, switched-mode power supplies, and overcurrent fault protection. The device consists of a precise, low-offset, linear Hall sensor circuit with a copper conduction path located near the surface of the die. Applied current flowing through this copper conduction path generates a magnetic field which is sensed by the integrated Hall IC and converted into a proportional voltage. Device accuracy is optimized through the close proximity of the magnetic signal to the Hall transducer. A precise, proportional voltage is provided by the low-offset, chopper-stabilized BiCMOS Hall IC, which is programmed for accuracy after packaging. The output of the device has a positive slope (>VIOUT(Q)) when an increasing current flows through the primary copper conduction path (from pins 1 and 2, to pins 3 and 4), which is the path used for current sensing. The internal resistance of this conductive path is 1.2 m typical, providing low power Continued on the next page...

ACS713-DS ACS713 Fully Integrated, Hall Effect-Based Linear Current Sensor with 2.1 kVRMS Voltage Isolation and a Low-Resistance Current Conductor The ACS713 is provided in a small, surface mount SOIC8 package. The leadframe is plated with 100% matte tin, which is compatible with standard lead (Pb) free printed circuit board assembly processes. Internally, the device is Pb-free, except for flip-chip high-temperature Pb-based solder balls, currently exempt from RoHS. The device is fully calibrated prior to shipment from the factory. Description (continued) loss. The thickness of the copper conductor allows survival of the device at up to 5x overcurrent conditions. The terminals of the conductive path are electrically isolated from the sensor leads (pins 5 through 8). This allows the ACS713 current sensor to be used in applications requiring electrical isolation without the use of opto-isolators or other costly isolation techniques.

The change in sensor output in response to a 1 A change through the primary conductor. The sensitivity is the product of the magnetic circuit sensitivity (G / A) and the linear IC amplifier gain (mV/G). The linear IC amplifier gain is programmed at the factory to optimize the sensitivity (mV/A) for the full-scale current of the device. Noise (VNOISE). The product of the linear IC amplifier gain (mV/G) and the noise floor for the Allegro Hall effect linear IC (1 G). The noise floor is derived from the thermal and shot noise observed in Hall elements. Dividing the noise (mV) by the sensitivity (mV/A) provides the smallest current that the device is able to resolve. Linearity (ELIN). The degree to which the voltage output from the sensor varies in direct proportion to the primary current through its full-scale amplitude. Nonlinearity in the output can be attributed to the saturation of the flux concentrator approaching the full-scale current. The following equation is used to derive the linearity: 100 1- causes. To convert this voltage to amperes, divide by the device sensitivity, Sens. Accuracy (ETOT). The accuracy represents the maximum deviation of the actual output from its ideal value. This is also known as the total ouput error. The accuracy is illustrated graphically in the output voltage versus current chart on the following page. Accuracy is divided into four areas: * 0 A at 25C. Accuracy of sensing zero current flow at 25C, without the effects of temperature. * 0 A over temperature. Accuracy of sensing zero current flow including temperature effects. * Full-scale current at 25C. Accuracy of sensing the full-scale current at 25C, without the effects of temperature. * Full-scale current over temperature. Accuracy of sensing fullscale current flow including temperature effects. Ratiometry. The ratiometric feature means that its 0 A output, VIOUT(Q), (nominally equal to 0.1 x VCC) and sensitivity, Sens, are proportional to its supply voltage, VCC . The following formula is used to derive the ratiometric change in 0 A output voltage, VIOUT(Q)RAT (%). 100 {[ (VIOUT_full-scale amperes -VIOUT(Q) ) 2 (VIOUT_half-scale amperes - VIOUT(Q)) [{ where VIOUT_full-scale amperes = the output voltage (V) when the sensed current approximates full-scale IP . Quiescent output voltage (VIOUT(Q)). The output of the sensor when the primary current is zero. For a unipolar supply voltage, it nominally remains at 0.1 x VCC. Thus, VCC = 5 V translates into VIOUT(Q) = 0.5 V. Variation in VIOUT(Q) can be attributed to the resolution of the Allegro linear IC quiescent voltage trim and thermal drift. Electrical offset voltage (VOE).

The time required for the sensor output to reflect a change in the primary current signal. Propagation delay is attributed to inductive loading within the linear IC package, as well as in the inductive loop formed by the primary conductor geometry. Propagation delay can be considered as a fixed time offset and may be compensated. I (%) 90 Primary Current Transducer Output 0 Propagation Time, tPROP t Response time (tRESPONSE).

The time interval between a) when the sensor reaches 10% of its full scale value, and b) when it reaches 90% of its full scale value. The rise time to a step response is used to derive the bandwidth of the current sensor, in which (-3 dB) = 0.35 / tr.

Such a lowpass filter improves the signal-to-noise ratio, and therefore the resolution, of the sensor output signal. However, the addition of an RC filter to the output of a sensor IC can result in undesirable sensor output attenuation -- even for dc signals. Signal attenuation, VATT , is a result of the resistive divider effect between the resistance of the external filter, RF (see Application 5), and the input impedance and resistance of the customer interface circuit, RINTFC. The transfer function of this resistive divider is given by: VATT = VIOUT temperature. Therefore, signal attenuation will vary as a function of temperature. Note that, in many cases, the input impedance, RINTFC , of a typical analog-to-digital converter (ADC) can be as low as 10 k. The ACS713 contains an internal resistor, a FILTER pin connection to the printed circuit board, and an internal buffer amplifier. With this circuit architecture, users can implement a simple RC filter via the addition of a capacitor, CF (see Application 6) from the FILTER pin to ground. The buffer amplifier inside of the ACS713 (located after the internal resistor and FILTER pin connection) eliminates the attenuation caused by the resistive divider effect described in the equation for VATT. Therefore, the ACS713 device is ideal for use in high-accuracy applications that cannot afford the signal attenuation associated with the use of an external RC low-pass filter. VCC Pin 8 RF + RINTFC RINTFC . Even if RF and RINTFC are designed to match, the two individual resistance values will most likely drift by different amounts over +5 V Pin 3 Pin 4 IP- IP- Dynamic Offset Cancellation Application 5. When a low pass filter is constructed externally to a standard Hall effect device, a resistive divider may exist between the filter resistor, RF, and the resistance of the customer interface circuit, RINTFC. This resistive divider will cause excessive attenuation, as given by the transfer function for VATT.
