TPS3823-33QDBVRQ1 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 | Low-level active reset output with push-pull output stage; pulling low forces reset active, remains low for 120 to 300 ms delay after MR released or VDD rises above threshold. |
| 2 | GND | power_in | Ground connection. |
| 3 | MR | input | Manual reset input, 0 to VDD+0.3 V; pulling low forces RESET active for timeout period after release; leave unconnected or connect to VDD when not used. |
| 4 | WDI | input | Watchdog timer input, 0 to VDD+0.3 V; reset triggered if input remains high or low beyond 0.9 to 2.5 s timeout; timer clears on reset active or falling edge of WDI. |
| 5 | VDD | power_in | Power supply voltage input, 1.1 V to 5.5 V recommended operating range; supplies device power and provides voltage monitoring threshold reference (3.3 V nominal for -33 variant). |
