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

TPS1HB35CQPWPRQ1 from Texas Instruments, in a HTSSOP-16. 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 reference. |
| 2 | SNS | output | Analog sense output for current sensing (2000 A/A ratio) and temperature sensing (0.0112 mA/°C coefficient). |
| 3 | LATCH | input | Digital input to set fault handling behavior between latched or auto-retry mode. |
| 4 | EN | input | Active high digital control input to enable or disable output switch. |
| 5 | ILIM | output | Analog output for current-limit setting; connect external resistor to set current-limit threshold from 2.5 A to 6 A for Version C. |
| 6 | VOUT | output | Channel output with on-resistance of 35 mΩ at TJ = 25°C and 70 mΩ at TJ = 150°C. |
| 7 | VOUT | output | Channel output with on-resistance of 35 mΩ at TJ = 25°C and 70 mΩ at TJ = 150°C. |
| 8 | VOUT | output | Channel output with on-resistance of 35 mΩ at TJ = 25°C and 70 mΩ at TJ = 150°C. |
| 9 | NC | unconnected | No connect; leave floating. |
| 10 | NC | unconnected | No connect; leave floating. |
| 11 | NC | unconnected | No connect; leave floating. |
| 12 | NC | unconnected | No connect; leave floating. |
| 13 | NC | unconnected | No connect; leave floating. |
| 14 | SEL1 | input | Diagnostics select input; enables temperature sensing when driven high; must be grounded through resistor to engage reverse battery protection. |
| 15 | NC | unconnected | No connect; leave floating. |
| 16 | DIA_EN | input | Active high digital input to enable analog sense, open-load detection, and short-to-battery diagnostics. |
| 17 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
