TPS1HB08FQPWPRQ1

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

TPS1HB08FQPWPRQ1 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; 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).

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.
