DESCRIPTION  
VSS  
RST  
The Microchip Technology Inc. MCP120/130 is a volt-  
age supervisory device designed to keep a microcon-  
troller in reset until the system voltage has reached the  
proper level and stabilized. It also operates as protec-  
tion from brown-out conditions when the supply voltage  
drops below a safe operating level. Both devices are  
available with a choice of seven different trip voltages  
and both have open drain outputs. The MCP130 has an  
internal 5 kΩ pullup resistor. Both devices have active  
low RESET pins. The MCP120/130 will assert the  
RESET signal whenever the voltage on the VDD pin is  
below the trip-point voltage.

APPLICATIONS INFORMATION  
The Need for Supervisory Circuits  
5V  
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 com-  
mon causes are brown-out conditions where the sys-  
tem supply drops below the operating level momentar-  
ily, and the second, is when a slowly decaying power  
supply causes the microcontroller to begin executing  
instructions without enough voltage to sustain SRAM  
and producing indeterminate results.

VTRIP - VDD (V)  
Many system designers implementing POR circuits are  
concerned about the minimum pulse width required to  
cause a reset. Figure 2-2 shows typical transient  
voltage below the trip point (VTRIP - VDD) vs. transient  
duration. 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. A 0.1 µF bypass  
cap mounted as close as possible to the VDD pin pro-  
vides additional transient immunity.

The timeout period (tRPU) determines how long the  
device remains in the reset condition. This is controlled  
by an internal RC timer and is effected by both VDD  
and temperature. The graph shown in Figure 2-3  
shows typical response for different VDD values and  
temperatures.
