RESET CIRCUIT (FOR SLOW
VDD POWER-UP)
FIGURE 10-12: EXTERNAL BROWN-OUT
PROTECTION CIRCUIT 1
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 flowing
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.
