DESCRIPTION
The Microchip Technology Inc. MCP120/130 is a voltage supervisory device designed to keep a microcontroller in reset until the system voltage has reached the
proper level and stabilized. It also operates as protection 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
2.1
The Need for Supervisory Circuits
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, 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.

Negative Going VDD Transients
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 provides additional transient immunity.

Effect of Temperature on Timeout
Period (tRPU)
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.

In the event the full Microchip part number cannot be marked on one line, it will
be carried over to the next line thus limiting the number of available characters
for customer specific information.
Standard OTP marking consists of Microchip part number, year code, week code, and traceability code.
For OTP marking beyond this, certain price adders apply. Please check with your Microchip Sales Office.
For QTP devices, any special marking adders are included in QTP price.
