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; in reverse battery the current flowing into GND must not exceed 50 mA (IGND absolute maximum, VBB < 0 V), so an external ground-protection network is recommended. |+| 2 | SNS | output | Analog sense output that carries a current proportional to the load current (IOUT/4600), the VBB voltage, or the device temperature as selected by SEL1 and SEL2, with an internal clamp at about 5.9 V; it also signals faults at ISNSFH, and the sense resistor should be terminated to the microcontroller ground. |+| 3 | LATCH | input | Selects fault handling: when low the switch automatically retries after a fault clears and tRETRY expires, and when high the switch stays latched off until LATCH is taken low; input thresholds are VIL 0.8 V and VIH 2 V, with an absolute range of -1 V to 7 V. |+| 4 | EN | input | Active-high switch enable with VIL 0.8 V and VIH 2 V thresholds, recommended range -1 V to 5.5 V, and an internal 1 MΩ pulldown; in the watchdog-enabled version E, EN must be pulsed periodically to keep the switch on. |+| 5 | ST | output | Open-drain, active-low status output that is pulled low on a fault (overtemperature, current limit, energy limit, open load or short to battery) and must be pulled up externally; VOL is at most 0.4 V at 1 mA, with an absolute range of -1 V to 7 V. |+| 6 | VOUT | output | Switched high-side output to the load; all six VOUT pins (6 to 11) must be shorted together on the PCB, and an internal VBB-to-VOUT clamp limits the voltage when inductive loads are switched off. |+| 7 | VOUT | output | Switched high-side output to the load; all six VOUT pins (6 to 11) must be shorted together on the PCB, and an internal VBB-to-VOUT clamp limits the voltage when inductive loads are switched off. |+| 8 | VOUT | output | Switched high-side output to the load; all six VOUT pins (6 to 11) must be shorted together on the PCB, and an internal VBB-to-VOUT clamp limits the voltage when inductive loads are switched off. |+| 9 | VOUT | output | Switched high-side output to the load; all six VOUT pins (6 to 11) must be shorted together on the PCB, and an internal VBB-to-VOUT clamp limits the voltage when inductive loads are switched off. |+| 10 | VOUT | output | Switched high-side output to the load; all six VOUT pins (6 to 11) must be shorted together on the PCB, and an internal VBB-to-VOUT clamp limits the voltage when inductive loads are switched off. |+| 11 | VOUT | output | Switched high-side output to the load; all six VOUT pins (6 to 11) must be shorted together on the PCB, and an internal VBB-to-VOUT clamp limits the voltage when inductive loads are switched off. |+| 12 | NC | unconnected | No internal connection; the datasheet lists this pin as not connected. |+| 13 | NC | unconnected | No internal connection; the datasheet lists this pin as not connected. |+| 14 | SEL1 | input | Diagnostic select 1 that chooses between VBB and junction-temperature sensing on SNS (with SEL2 selecting load current when both are low); input thresholds are VIL 0.8 V and VIH 2 V, with an internal 1 MΩ pulldown. |+| 15 | SEL2 | input | Diagnostic select 2 that works with SEL1 to choose the SNS signal and must be connected to module ground through RPROT to enable automatic turn-on during reverse battery; with SEL2 = 0 V, VBB measurement is unavailable, and input thresholds are VIL 0.8 V and VIH 2 V. |+| 16 | DIA_EN | input | Active-high diagnostic enable that activates analog sensing, open-load and short-to-battery detection when the switch is off; input thresholds are VIL 0.8 V and VIH 2 V, recommended range -1 V to 5.5 V, and an internal 1 MΩ pulldown. |+| 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 | Global Sourcing Parts |+| Pins | 17 |++## CAD (KiCad official)++- Symbol: `TPS1HA08BQPWPRQ1`+- Footprint: `Package_SO:TSSOP-16-1EP_4.4x5mm_P0.65mm`+- 3D model: HTSSOP-16-EP (KiCad packages3D, STEP)+- 3D model files: `tps1ha08bqpwprq1-etched.step` / `tps1ha08bqpwprq1-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `tps1ha08bqpwprq1.step` / `tps1ha08bqpwprq1.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/tps1ha08-q1) (62 pp, sha256 `a1d902aeb153f667`, retrieved 2026-10-08, tier: lcsc)+- **Datasheet language:** Chinese.
