TPS3820-33QDBVRQ1

Texas Instruments · Supervisor And Reset ICs · SOT-23-5

TPS3820-33QDBVRQ1 from Texas Instruments, in a SOT-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 Active-low reset output with push-pull output stage (TPS3820-xx-Q1) that goes low when VDD falls below VIT- and stays low for the delay time td after VDD rises above the threshold.
2 GND power_in Ground connection for the device.
3 MR input Manual reset input; pulling it low forces RESET active, and RESET stays low for the timeout period after MR returns high, so leave it unconnected or tie it to VDD when unused.
4 WDI input Watchdog timer input; if WDI stays high or low longer than the timeout period a reset is triggered, and the timer is cleared on a WDI falling edge or when RESET is asserted.
5 VDD power_in Supply voltage pin that powers the device and monitors the supply; recommended operating range is 1.1 V to 5.5 V.
