TPS2483PW from Texas Instruments, in a TSSOP-20. 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 | SDA | bidirectional | Serial-bus data line, open-drain input/output with Schmitt-trigger input and spike suppression for the I2C/SMBus interface. |
| 2 | SCL | input | Serial-bus clock line, high-impedance input for the I2C/SMBus interface. |
| 3 | ALERT | output | Open-drain multi-function serial-bus alert output that can be programmed to go low when a user-defined threshold is exceeded. |
| 4 | VS | power_in | Monitor-section bias-supply input for POR1, control logic, ADC and serial-bus interface, typically 2.7 V to 5.5 V. |
| 5 | N/C | unconnected | No connection; tie to GND or float. |
| 6 | EN | input | Hotswap-section enable input with hysteresis between its upper and lower thresholds; it can be tied to VCC to always enable the device. |
| 7 | VREF | power_in | Reference voltage output used to set the PROG power-limit threshold, with a recommended reference source current of 0 to 1 mA. |
| 8 | PROG | input | Pass-MOSFET power-limit programming input, normally 0.4 V to 4.0 V, and voltages above 4 V must not be applied. |
| 9 | TIMER | input | Fault-timing capacitor connection to GND; TIMER reaching 4 V latches off the TPS2482 or starts a retry for the TPS2483, and the pin should be tied to ground if the feature is unused. |
| 10 | GND | power_in | Common system ground reference for all other input and output voltages. |
| 11 | PG | output | Open-drain power-good output that goes high after pass-MOSFET VDS falls below 1.25 V and a 9-ms deglitch time elapses, and is low when VDS exceeds 2.7 V or UVLO is active. |
| 12 | OUT | input | Input that senses pass-MOSFET source voltage for power-limit protection and PG determination; if the load can drive OUT below ground, a clamp diode to GND is needed to keep VOUT above -0.3 V. |
| 13 | GATE | output | High-side pass-MOSFET gate-drive output with a 22 µA pull-up from the charge pump and a pull-down to ground of at least 75 mA, clamped internally to OUT. |
| 14 | SENSE | input | Input that senses pass-MOSFET drain voltage and the downstream side of the current-shunt RS for constant-power and current limiting, and should not be driven to a large voltage difference from VCC. |
| 15 | VCC | power_in | Hotswap-section bias-supply input and positive reference for shunt sensing; it must exceed the POR2 threshold (about 6 V) and UVLO turn-on (about 8.4 V) before GATE can be driven, with a recommended range of 9 V to 80 V. |
| 16 | GND | power_in | Common system ground reference for all other input and output voltages. |
| 17 | VINM | input | Kelvin-connected negative (load) side of the current-sense resistor, which also serves as the bus-voltage measurement point to GND. |
| 18 | VINP | input | Kelvin-connected positive (source) side of the current-sense resistor for the differential shunt voltage input. |
| 19 | A1 | input | Serial-bus address input that may be tied to GND, VS, SDA, or SCL, which together with A0 selects one of 16 slave addresses per Table 8. |
| 20 | A0 | input | Serial-bus address input that may be tied to GND, VS, SDA, or SCL, which together with A1 selects one of 16 slave addresses per Table 8. |
