GS6332 and GS6333 Vishay formerly General Semiconductor 3 Pin, Low-Power, µP Reset Circuits Pin Configuration SOT-23 (Top View) 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. GND 1 3 Vcc Reset/ Reset 2 • 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. VCC VCC VCC GS6332 GS6333 RESET (RESET) GND RESET INPUT µP • 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. GND 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 • Vcc transient immunity • No external components Applications • • • • Computers Critical µP/µC power monitoring Battery powered equipment Automotive electronics Document Number 74810 22-May-02 www.vishay.com 1 GS6332 and GS6333 Vishay formerly General Semiconductor Ordering Information Reset Timeout Period (Typical) 1: 1.5mS 2: 30mS 3: 150mS (Standard) Reset Voltage Options (Typical) 15: 16: 18: 19: 20: 21: 22: 23: 24: 25: 1.5V 1.6V (Standard) 1.8V (Standard) 1.9V 2.0V (Standard) 2.1V 2.2V (Standard) 2.3V (Standard) 2.4V 2.5V Marking Codes GS6333 Product No. GS6333UR15D1 GS6333UR15D2 GS6333UR15D3 GS6333UR16D1 Marking ADxxx AExxx AGxxx AHxxx AIxxx AKxxx ALxxx AMxxx ANxxx AOxxx APxxx ARxxx ASxxx ATxxx AVxxx AWxxx AXxxx AYxxx AZxxx BAxxx BBxxx BCxxx BDxxx BExxx BGxxx BHxxx BIxxx BKxxx BLxxx BMxxx GS6332 Product No. GS6332UR15D1 GS6332UR15D2 GS6332UR15D3 GS6332UR16D1 GS6332UR16D2 GS6332UR16D3 GS6332UR18D1 GS6332UR18D2 GS6332UR18D3 GS6332UR19D1 GS6332UR19D2 GS6332UR19D3 GS6332UR20D1 GS6332UR20D2 GS6332UR20D3 GS6332UR21D1 GS6332UR21D2 GS6332UR21D3 GS6332UR22D1 GS6332UR22D2 GS6332UR22D3 GS6332UR23D1 GS6332UR23D2 GS6332UR23D3 GS6332UR24D1 GS6332UR24D2 GS6332UR24D3 GS6332UR25D1 GS6332UR25D2 GS6332UR25D3 Marking BNxxx BOxxx BPxxx BRxxx BSxxx BTxxx BVxxx BWxxx BXxxx BYxxx BZxxx CAxxx CBxxx CCxxx CDxxx CExxx CGxxx CHxxx CIxxx CKxxx CLxxx CMxxx CNxxx COxxx CPxxx CRxxx CSxxx CTxxx CVxxx CWxxx Reset Active High GS6332URxxDx GS6333URxxDx Reset Active Low GS6333UR16D2 GS6333UR16D3 GS6333UR18D1 GS6333UR18D2 GS6333UR18D3 GS6333UR19D1 GS6333UR19D2 GS6333UR19D3 GS6333UR20D1 Sample stock is generally available on standard parts.
