TPS3806J20DBVR from Texas Instruments, in a SOT-23-6. 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 | RSTSENSE | output | Active-low open-drain reset output asserted from LSENSE, which needs an external pull-up resistor because the output is an open-drain MOSFET. |
| 2 | GND | power_in | Ground reference; all voltage values in the datasheet are stated with respect to GND. |
| 3 | RESET | output | Active-low open-drain reset output driven from VDD, which needs an external pull-up resistor. |
| 4 | VDD | power_in | Input supply voltage and fixed sense input; the recommended supply range is 1.3 V to 6 V. |
| 5 | LSENSE | input | Adjustable sense input with a 1.207 V nominal threshold set by external resistor divider R1 and R2. |
| 6 | HSENSE | input | Adjustable hysteresis input that sets the upper voltage threshold for the wide hysteresis window. |
