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; all device operating voltages are measured relative to this GND pin. |+| 2 | SNS | output | Analog sense output that carries current proportional to load current (version F cannot measure device temperature) and goes to the fault level ISNSFH when a fault is indicated. |+| 3 | LATCH | input | Fault-handling select input: high latches the switch off until LATCH is taken low, while low (or floating, or grounded through RPROT) gives automatic retry after tRETRY. |+| 4 | EN | input | Active-high channel control input with VIL max 0.8 V, VIH min 2.0 V, and an internal pull-down of 0.5 to 2 MΩ. |+| 5 | FLT | output | Version F only: open-drain fault output with pull-down that is pulled low when a fault is indicated, and requires a 10 kΩ pull-up to a 5 V rail. |+| 6 | VOUT | output | Protected high-side channel output to the load, limited by the device current limit and clamped during inductive turn-off. |+| 7 | VOUT | output | Protected high-side channel output to the load, limited by the device current limit and clamped during inductive turn-off. |+| 8 | VOUT | output | Protected high-side channel output to the load, limited by the device current limit and clamped during inductive turn-off. |+| 9 | VOUT | output | Protected high-side channel output to the load, limited by the device current limit and clamped during inductive turn-off. |+| 10 | VOUT | output | Protected high-side channel output to the load, limited by the device current limit and clamped during inductive turn-off. |+| 11 | VOUT | output | Protected high-side channel output to the load, limited by the device current limit and clamped during inductive turn-off. |+| 12 | NC | unconnected | No connection; leave floating. |+| 13 | NC | unconnected | No connection; leave floating. |+| 14 | SEL1 | input | Diagnostic select input that has no function on version F, so it must be connected through an RPROT resistor to IC GND. |+| 15 | NC | unconnected | No connection; leave floating. |+| 16 | DIA_EN | input | Active-high diagnostic enable input with VIL max 0.8 V, VIH min 2.0 V, and an internal pull-down of 0.5 to 2 MΩ; when unused, analog sense, open-load and battery-short diagnostics are unavailable. |+| 17 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | HTSSOP-16-EP |+| Category | Power Supply Chip |+| Pins | 17 |++## CAD (KiCad official)++- Symbol: `TPS1HB08FQPWPRQ1`+- Footprint: `Package_SO:TSSOP-16-1EP_4.4x5mm_P0.65mm`+- 3D model: HTSSOP-16-EP (KiCad packages3D, STEP)+- 3D model files: `tps1hb08fqpwprq1-etched.step` / `tps1hb08fqpwprq1-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `tps1hb08fqpwprq1.step` / `tps1hb08fqpwprq1.glb` are the bare package body.++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/cn/lit/gpn/tps1hb08-q1) (53 pp, sha256 `d93a19efaa6d5443`, retrieved 2026-10-08, tier: lcsc)+- **Datasheet language:** Chinese.
