Note 1:
External Power-on Reset circuit is required only
if V
DD power-up slope is too slow. The diode D
helps discharge the capacitor quickly when V
DD
powers down.
2:
R < 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 flowing
into MCLR from external capacitor C, in the
event of MCLR/V
PP pin breakdown due to
Electrostatic Discharge (ESD), or Electrical
Overstress (EOS).

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.

Note 1:
This circuit will activate RESET when V
DD goes
below (Vz + 0.7V), where Vz = Zener voltage.

Resistors should be adjusted for the character-
istics of the transistor.

This brown-out circuit is less expensive,
albeit less accurate. Transistor Q1 turns off
