Description
• The GS6333 and GS6332 are system supervisor circuits
designed to monitor VCC 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 (TD1). Reset is maintained active for a
time period (TD2), after the Vcc rises above the threshold
voltage.

• To prevent jitter, the reset threshold voltage has a built-in
hysteresis of 0.4% of VTH
.
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 Vcc = 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
• Vcc transient immunity
• No external components

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.
