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 volitile memory (RAM), thus producing indeterminate results. Figure 4-1 shows a typical application circuit. The MCP102/103/121/131 are voltage supervisor devices designed to keep a microcontroller in reset until the system voltage has reached and stabilized at the proper level for reliable system operation. These devices also operate as protection from brown-out conditions when the system supply voltage drops below a safe operating level. VDD VDD VDD RPU PICmicro® Microcontroller MCLR (reset input) (Active-Low) VSS The RST output pin operation determines how the device can be used, and indicates when the system should be forced into reset. To accomplish this, an internal voltage reference is used to set the voltage trip point (VTRIP). Additionally, there is a hysteresis on this trip point. When the falling edge of VDD crosses this voltage threshold, the reset power-down timer (TRPD) starts. When this delay timer times out (TRPD), the RST pin is forced low. When the rising-edge of VDD crosses this voltage threshold, the reset power-up timer (TRPU) starts. When this delay timer times out (TRPU), the RST pin is forced high, the reset power-up timer is active and there is additional system current. The actual voltage trip point (VTRIPAC) will be between the minimum trip point (VTRIPMIN) and the maximum trip point (VTRIPMAX). The hysteresis on this trip point and the delay timer (TRPU) are to remove any “jitter” that would occur on the RST pin when the device VDD is at the trip point. Figure 4-2 shows the waveform of the RST pin as determined by the VDD voltage, while Table 4-1 shows the state of the RST pin. The VTRIP specification is for falling VDD voltages. When the VDD voltage is rising, the RST will not be driven high until VDD is at VTRIP + VHYS. Once VDD has crossed the voltage trip point, there is also a minimal delay time (TRPD) before the RST pin is driven low. 0.1 µF MCP1XX RST VSS Note 1: Resistor RPU may be required with the MCP121 due to the open-drain output. Resistor RPU may not be required with the MCP131 due to the internal pull-up resistor. The MCP102 and MCP103 do not require the external pull-up resistor.

This time is referred to as transient duration and is 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 MCP102/103/121/ 131 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 2-32 shows the transient response characteristics for the MCP102/103/121/131. A 0.1 µF bypass capacitor, mounted as close as possible to the VDD pin, provides additional transient immunity (refer to Figure 4-1). Figure 4-4 illustrates the device current states. While the system is powering down, the device has a low current. This current is dependent on the device VDD and trip point. When the device VDD rises through the voltage trip point (VTRIP), an internal timer starts. This timer consumes additional current until the RST pin is driven (or released) high. This time is known as the Reset Power-up Time (tRPU). Figure 4-4 shows when tRPU is active (device consuming additional current).

This is affected by both VDD and temperature. Typical responses for different VDD values and temperatures are shown in Figures 2-26, 2-27 and 2-28.  2004 Microchip Technology Inc.
