TPV811S-4LTR

3PEAK · Supervisor and Reset ICs · SOT-143-4

TPV811S-4LTR from 3PEAK, in a SOT-143-4. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 GND power_in Device ground reference (0 V). All voltages are referenced to this pin.
2 RESET output Active-Low Reset push-pull output stage (TPV811). Asserted (driven low) whenever VCC falls below the reset threshold VTH and remains asserted for the 200 ms (typical) reset timeout after VCC returns above VTH. Output is guaranteed valid down to VCC = 1 V.
3 MR input Manual Reset input, active low. Forcing this pin low for at least 1 µs generates a reset pulse on the RESET output. Features an internal 50 kΩ pull-up to VCC, so it may be left floating if unused.
4 VCC power_in Power supply input; this is also the voltage being monitored by the supervisor. Typical quiescent current 2.2 µA.
