VISHAY GS6332 and GS6333 Data Sheet
Summary
Reliably monitor power supply voltage in demanding digital applications with these precision supervisor circuits. Engineered for critical embedded systems and battery-powered devices, they ensure stable operation by detecting voltage drops and triggering a controlled reset signal to the host processor or microcontroller. This comprehensive manual provides detailed technical specifications, operational curves, precise reset thresholds (1.5V–2.5V), and ordering information necessary for designing robust, low-power computing solutions.

Pin Configuration Description SOT-23 (Top View)
• 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. Vcc • When the processor power supply voltage drops below the reset threshold, the reset output is driven active, in Reset/ less than 40µs (TD1). Reset is maintained active for a
Reset 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 suit-
