| MC34064, MC33064, NCV33064 Undervoltage Sensing Circuit The MC34064 is an undervoltage sensing circuit specifically designed for use as a reset controller in microprocessor-based systems. It offers the designer an economical solution for low voltage detection with a single external resistor. The MC34064 features a trimmed-in-package bandgap reference, and a comparator with precise thresholds and built-in hysteresis to prevent erratic reset operation. The open collector reset output is capable of sinking in excess of 10 mA, and operation is guaranteed down to 1.0 V input with low standby current. The MC devices are packaged in 3-pin TO-226AA, 8-pin SO-8 and Micro8 surface mount packages. The NCV device is packaged in SO-8 and TO-226AA. Applications include direct monitoring of the 5.0 V MPU/logic power supply used in appliance, automotive, consumer and industrial equipment. * Trimmed-In-Package Temperature Compensated Reference * Comparator Threshold of 4.6 V at 25C * Precise Comparator Thresholds Guaranteed Over Temperature * Comparator Hysteresis Prevents Erratic Reset * Reset Output Capable of Sinking in Excess of 10 mA * Internal Clamp Diode for Discharging Delay Capacitor * Guaranteed Reset Operation with 1.0 V Input * Low Standby Current * Economical TO-226AA, SO-8 and Micro8 Surface Mount Packages Input 2 (2) Reset 1 (1) http://onsemi.com TO-226AA P SUFFIX CASE 29 Pin 1.

The hysteresis equation has been simplified and does not account for the change of input current Iin as VCC crosses the comparator threshold (Figure 4). An increase of the lower threshold DVth(lower) will be observed due to Iin which is typically 340 mA at 4.59 V. The equations are accurate to 10% with RH less than 150 W and RL between 1.5 kW and 10 kW. Figure 10.
