TECH PUBLIC · Power Distribution Switches · SOT-23-5
TPMAX40203AUK+T from TECH PUBLIC, in a SOT-23-5. 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 | VDD | power_in | Power supply input. Operating range 1.5 V to 5.5 V; absolute max 6 V. Also serves as the switch input (VIN) feeding the P-channel MOSFET to OUT. |
| 2 | GND | power_in | Device ground reference for control logic and output discharge return. |
| 3 | EN | input | Enable input, active high. VIH ≥ 1.2 V, VIL ≤ 0.4 V (VIN = 1.5-5.5 V). Absolute max 6 V. Internal ~10 MΩ pull-down to GND holds the switch off when floating; EN low activates the ~85Ω quick output discharge. |
| 4 | NC | unconnected | No connect. Internally not connected; leave floating or tie to GND/VDD per board convenience. |
| 5 | OUT | power_out | Switched output voltage pin. Delivers up to 2 A continuous with typical RON of 32 mΩ at VIN = 5.5 V. Discharged through ~85Ω to GND when EN is low. Reverse current blocking engages when VOUT exceeds VIN by ~25 mV. |
