Texas Instruments · Supervisor And Reset ICs · SOT-23-5
TPS3823-50DBVR 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 | Low-level active reset output with push-pull stage; asserted when VDD drops below 4.55V threshold or when manual reset input is pulled low. |
| 2 | GND | power_in | Ground connection. |
| 3 | MR | input | Manual reset input with internal 90kΩ pull-up resistor; pulling low asserts RESET output until timeout period expires; leave unconnected or connect to VDD when not used. |
| 4 | WDI | input | Watchdog timer input; if held high or low for more than 1.6 seconds (typical timeout), RESET is asserted; timer clears on WDI falling edge or when RESET becomes active. |
| 5 | VDD | power_in | Power supply voltage input operating from 1.1V to 5.5V; monitors supply against 4.55V threshold to assert reset output. |
