CAT823STDI-GT3

onsemi · Monitors & Reset Circuits · TSOT-23-5

CAT823STDI-GT3 from onsemi, in a TSOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 RESET output CMOS push-pull active-low reset output, held active for a 140 ms minimum timeout (tRP) after VCC rises above the reset threshold, with a 20 mA absolute maximum output current.
2 GND power_in Ground reference for the device.
3 MR input Active-low manual reset input with an internal 52 kΩ pull-up to VCC, driven low by a pushbutton, open-drain output or CMOS output, with VIL max 0.3 x VCC and VIH min 0.7 x VCC.
4 WDI input Watchdog timer input that must toggle within the 1.12 s minimum timeout period to avoid a reset, and can be disabled by tri-stating or leaving it open.
5 VCC power_in Power supply input, recommended 1.2 to 5.5 V over -40 to +85 °C, with a 6 V absolute maximum.
