Texas Instruments · AC-DC Controllers and Regulators · HTSSOP-28-EP

TPS4H160AQPWPRQ1 from Texas Instruments, in a HTSSOP-28-EP. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 GND power_in Device ground.
2 NC unconnected No internal connection.
3 IN1 input Input control for channel 1 activation. Internal pulldown. Absolute max input voltage 7 V.
4 IN2 input Input control for channel 2 activation. Internal pulldown.
5 IN3 input Input control for channel 3 activation. Internal pulldown.
6 IN4 input Input control for channel 4 activation. Internal pulldown.
7 ST1 output Open-drain diagnostic status output for channel 1 (active low). Requires external pull-up. Version A only.
8 ST2 output Open-drain diagnostic status output for channel 2 (active low). Requires external pull-up. Version A only.
9 ST3 output Open-drain diagnostic status output for channel 3 (active low). Requires external pull-up. Version A only.
10 ST4 output Open-drain diagnostic status output for channel 4 (active low). Requires external pull-up. Version A only.
11 CL input Adjustable current limit setting pin. Connect an external resistor to GND to program the current limit; tie to device GND if external current limit is not used.
12 GND power_in Device ground.
13 THER input Thermal shutdown behavior control: selects latch-off or auto-retry mode. Internal pulldown.
14 DIAG_EN input Enable-disable pin for diagnostics. Internal pulldown.
15 OUT4 output Output of the channel 4 high-side switch, connected to the load.
16 OUT4 output Output of the channel 4 high-side switch, connected to the load (parallel pin).
17 OUT3 output Output of the channel 3 high-side switch, connected to the load.
18 OUT3 output Output of the channel 3 high-side switch, connected to the load (parallel pin).
19 NC unconnected No internal connection.
20 VS power_in Supply voltage input (3.4 V to 40 V operating; 48 V abs max). Multiple VS pins should be tied together.
21 VS power_in Supply voltage input (parallel pin).
22 VS power_in Supply voltage input (parallel pin).
23 VS power_in Supply voltage input (parallel pin).
24 NC unconnected No internal connection.
25 OUT2 output Output of the channel 2 high-side switch, connected to the load.
26 OUT2 output Output of the channel 2 high-side switch, connected to the load (parallel pin).
27 OUT1 output Output of the channel 1 high-side switch, connected to the load.
28 OUT1 output Output of the channel 1 high-side switch, connected to the load (parallel pin).
29 PAD passive Exposed thermal pad. Connect to device GND or leave floating; connect to a large copper pour for heat dissipation.

Two STEP files. Same geometry, different body top:

File Size Use it when
tps4h160aqpwprq1.step 367 KB You want the bare part, or you mark your own boards.
tps4h160aqpwprq1-etched.step 4.0 MB You want the part with TPS4H160AQPWPRQ1 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 1000 faces against 455 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: Texas Instruments datasheet (42 pp, sha256 0b0a66a56bf2bd3b, retrieved 2026-08-17, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
