Note
1:
External Power-on Reset circuit is required
only if VDD power-up slope is too slow. The
diode D helps discharge the capacitor quickly
when VDD powers down.
2:
< 40 k
is recommended to make sure that
voltage drop across R does not violate the
device’s electrical specification.
3: R1 = 100
to 1 k will limit any current flow-
ing into MCLR from external capacitor C, in
the event of MCLR/VPP pin breakdown due to
Electrostatic Discharge (ESD), or Electrical
Overstress (EOS).

Note
1:
This circuit will activate RESET when VDD
goes below (Vz + 0.7V), where Vz = Zener
voltage.
2: Internal Brown-out Reset circuitry should
be disabled when using this circuit.

Note
1: This brown-out circuit is less expensive,
albeit less accurate. Transistor Q1 turns off
when VDD is below a certain level such that:
2: Internal brown-out detection should be dis-
abled when using this circuit.
3: Resistors should be adjusted for the charac-
teristics of the transistor.

This brown-out protection circuit employs Microchip
Technology’s MCP809 microcontroller supervisor. The
MCP8XX and MCP1XX families of supervisors provide
push-pull and open collector outputs with both high and
low active RESET pins. There are 7 different trip point
selections to accommodate 5V and 3V systems.
