P Reset Circuits
Description
The GS6333 and GS6332 are system supervisor circuits
designed to monitor V
CC
in digital systems and provide
a reset signal to the host processor when necessary. No
external components are required.
When the processor power supply voltage drops below
the reset threshold, the reset output is driven active, in
less than 40
μ
s (T
D1
). Reset is maintained active for a
time period (T
D2
), after the V
cc
rises above the threshold
voltage.
To prevent jitter, the reset threshold voltage has a built-in
hysteresis of 0.4% of V
TH
.
The GS6333 has an active-low reset output, while the
GS6332 has an active-high reset output. Both devices
have push/pull output drives.
The reset signal is guaranteed valid, down to V
cc
= 1.0V.
Low supply current of 3
μ
A makes these devices well suit-
ed for battery powered applications. They are designed
to reject fast transients from causing false resets.
Both devices are available in a space-saving SOT-23
package.
Features
Tight reset voltage tolerances ± 1.8%
Low supply current: <3

Other threshold voltage options available from 1.5V to
2.5V in approximately 100mV increments
Three reset active time-out period options:
typical 1.5mS, 30mS, 150mS
Reset output guaranteed down to 1.0V
