Description
The MCP111/112 are voltage-detecting devices designed to keep a microcontroller in reset until the system voltage has stabilized at the appropriate level for reliable system operation. These devices also operate as protection from brown-out conditions when the system supply voltage drops below the specified threshold voltage level. Eight different trip voltages are available.

Trip point is 1.5% from typical value. Trip point is 2.5% from typical value. This specification allows this device to be used in PICmicro(R) microcontroller applications that require the In-Circuit Serial ProgrammingTM (ICSPTM) feature (see device-specific programming specifications for voltage requirements). This specification DOES NOT allow a continuous high voltage to be present on the open-drain output pin (VOUT). The total time that the VOUT pin can be above the maximum device operational voltage (5.5V) is 100 sec. Current into the VOUT pin should be limited to 2 mA. It is recommended that the device operational temperature be maintained between 0C to 70C (+25C preferred). For additional information, please refer to Figure 2-28. This parameter is established by characterization and is not 100% tested.

4.0 APPLICATION INFORMATION
4.1 VTRIP Operation
For many of today's microcontroller applications, care must be taken to prevent low-power conditions that can cause many different system problems. The most common causes are brown-out conditions, where the system supply drops below the operating level momentarily. The second most common cause is when a slowly decaying power supply causes the microcontroller to begin executing instructions without sufficient voltage to sustain SRAM, thus producing indeterminate results. Figure 4-1 shows a typical application circuit. VDD 3 VDD MCP11X VOUT VSS 2 1 VDD RPU
(1)
The voltage trip point (VTRIP) is determined on the falling edge of VDD. The actual voltage trip point (VTRIPAC) will be between the minimum trip point (VTRIPMIN) and the maximum trip point (VTRIPMAX). There is a hysteresis on this trip point to remove any "jitter" that would occur on the VOUT pin when the device VDD is at the trip point. Figure 4-2 shows the state of the VOUT pin as determined by the VDD voltage. The VTRIP specification is for falling VDD voltages. When the VDD voltage is rising, the VOUT pin will not be driven high until VDD is at VTRIP + VHYS.

Note 1: RPU may be required with the MCP111 due to the open-drain output. Resistor RPU is not required with the MCP112.

4.2 Negative Going VDD Transients 4.3
The minimum pulse width (time) required to cause a reset may be an important criteria in the implementation of a Power-on Reset (POR) circuit. This time is referred to as transient duration, defined as the amount of time needed for these supervisory devices to respond to a drop in VDD. The transient duration time is dependant on the magnitude of VTRIP - VDD. Generally speaking, the transient duration decreases with increases in VTRIP - VDD. Figure 4-3 shows a typical transient duration vs. reset comparator overdrive for which the MCP111/112 will not generate a reset pulse. It shows that the farther below the trip point the transient pulse goes, the duration of the pulse required to cause a reset gets shorter. Figure 2-18 shows the transient response characteristics for the MCP111/112. A 0.1 F bypass capacitor, mounted as close as possible to the VDD pin, provides additional transient immunity (refer to Figure 4-1).
Effect of Temperature on Time-out Period (tRPU)
The time-out period (tRPU) determines how long the device remains in the reset condition. This is affected by both VDD and temperature. The graph shown in Figures 2-22, 2-23 and 2-24 show the typical response for different VDD values and temperatures.
4.4
Using in PICmicro(R) Microcontroller ICSPTM Applications (MCP111 only)
Figure 4-4 shows the typical application circuit for using the MCP111 for voltage supervisory function when the PICmicro microcontroller will be programmed via the In-Circuit Serial ProgrammingTM (ICSP) feature. Additional information is available in TB087, "Using Voltage Supervisors with PICmicro(R) Microcontroller Systems which Implement In-Circuit Serial ProgrammingTM", DS91087. Note: It is recommended that the current into the RST pin be current limited by a 1 k resistor. VDD/VPP 0.1 F VDD RPU VDD PICmicro(R) MCU MCLR (reset input) (Active-Low) VSS
