GS6333 General 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.
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 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.
