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

Supply (VCC) Transients

These devices have a certain immunity to fast negative
going transients.The graph titled “Transient Rejection”
shows the maximum allowable transient amplitude and
duration to avoid triggering an unintended reset. As
shown in the graph shorter transients can have larger
amplitudes without triggering resets.
