3-Pin Ultra-Low-Voltage
µ
C Supervisor Circuit
General Description
The FM6332/3/4 are low-power supervisor circuits that monitor a
microprocessor power supply or other system voltage and issue
a reset pulse when a fault condition exists. The threshold voltages
offered accommodate systems with requirements below the com-
mon 5.0V and 3.3V levels.
The devices feature a precision temperature-compensated volt-
age reference and comparator. When V
CC
falls to the threshold
voltage, a RESET pulse is issued, holding the output in the active
state (LOW for FM6333/4 and HIGH for FM6332). When power
rises above V
TH
, the reset remains for approximately 250 ms to
allow the system clock and other circuits to stabilize.
