Description

• The GS6333 and GS6332 are system supervisor circuits

designed to monitor V_CCin digital systems and provide

a reset signal to the host processor when necessary. No

external components are required.

GND

• 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 V_ccrises above the threshold

voltage.

Reset/

Reset

• To prevent jitter, the reset threshold voltage has a built-in

hysteresis of 0.4% of V_TH

Fig. 1 – Typical Application Diagram

• 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 well suit-

ed for battery powered applications. They are designed

to reject fast transients from causing false resets.

Features

• Tight reset voltage tolerances ± 1.8%

• Low supply current: <3µA

• Precision monitoring of 1.8V and 2.5V

powersupply voltages

Applications

• Other threshold voltage options available from 1.5V to

2.5V in approximately 100mV increments

• Computers

• Critical µP/µC power monitoring

• Battery powered equipment

• Automotive electronics

• Three reset active time-out period options:

typical 1.5mS, 30mS, 150mS

• Reset output guaranteed down to 1.0V

• V_cctransient immunity

• No external components

Supply (V ) 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.
