3 Pin, Low-Power, µP 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 40µs (T
D1
). Reset is maintained active for a
time period (T
D2
), after the Vccrises 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 3µA makes these devices w ell suited 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: <3µA
• Precision monitoring of 1.8V and 2.5V
powersupply voltages
• 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
• V
cc
transient immunity
• No external components
