# TPS2HB50BQPWPRQ1

**Texas Instruments** · Power Distribution Switches · HTSSOP-16-EP

TPS2HB50BQPWPRQ1 from Texas Instruments, in a HTSSOP-16-EP. 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 | GND | power_in | Device ground. |
| 2 | SNS | output | Sense output for analog current, temperature and fault diagnostics; recommended voltage is -1 V to 7 V (absolute maximum -1 V to 18 V), and it should be grounded through a 1-kΩ resistor if unused. |
| 3 | LATCH | input | Sets fault handling behavior (latched or auto-retry); recommended voltage is -1 V to 5.5 V (absolute maximum -1 V to 7 V). |
| 4 | EN1 | input | Channel 1 control input, active high; recommended voltage is -1 V to 5.5 V (absolute maximum -1 V to 7 V). |
| 5 | ILIM1 | output | Connect a pull-up resistor to VBB to set the current-limit threshold on CH1; leaving it floating selects the default internal threshold. |
| 6 | VOUT1 | output | Channel 1 output. |
| 7 | VOUT1 | output | Channel 1 output. |
| 8 | VOUT1 | output | Channel 1 output. |
| 9 | VOUT2 | output | Channel 2 output. |
| 10 | VOUT2 | output | Channel 2 output. |
| 11 | VOUT2 | output | Channel 2 output. |
| 12 | ILIM2 | output | Connect a pull-up resistor to VBB to set the current-limit threshold on CH2; leaving it floating selects the default internal threshold. |
| 13 | EN2 | input | Channel 2 control input, active high; recommended voltage is -1 V to 5.5 V (absolute maximum -1 V to 7 V). |
| 14 | SEL1 | input | Diagnostics select 1; selects the TJ sensing feature, and floating or grounding through RPROT is allowed when unused; recommended voltage is -1 V to 5.5 V. |
| 15 | SEL2 | input | Diagnostics select 2; with SEL2 = 0 V, CH2 current sensing and CH2 open-load detection are not available; recommended voltage is -1 V to 5.5 V. |
| 16 | DIA_EN | input | Diagnostic enable, active high; recommended voltage is -1 V to 5.5 V (absolute maximum -1 V to 7 V). |
| 17 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
