TPS1HB50AQPWPRQ1 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 reference and return path for all internal circuits and external currents; 0V potential node for all signal measurements. |
| 2 | SNS | output | Proportional current sense output sourcing IOUT/KSNS (KSNS=1500) when SEL1=0, or temperature sense current (dISNST/dT=0.0112 mA/°C) when SEL1=1, or ISNSFH (4.5 mA typ) during fault indication. |
| 3 | LATCH | input | Latch control input with 350 mV hysteresis; high level (VIH≥2.0V) latches output after fault events, low level (VIL<0.8V) enables auto-retry after tRETRY (1-3 ms) expiration. |
| 4 | EN | input | Active-high enable control input with 350 mV hysteresis; high level (VIH≥2.0V) enables output switch, low level (VIL<0.8V) disables output. |
| 5 | ILIM | output | Programmable current limit threshold output; connect external resistor (RILIM 5 kΩ to 25 kΩ) from this pin to VBB to set current limit (ICL = KCL / RILIM). |
| 6 | VOUT | output | High-side switch output pin (one of three parallel pins); RON 50 mΩ at TJ=25°C and 100 mΩ at TJ=150°C, with VDS clamp voltage 40-46V for inductive load protection. |
| 7 | VOUT | output | High-side switch output pin (one of three parallel pins); RON 50 mΩ at TJ=25°C and 100 mΩ at TJ=150°C, with VDS clamp voltage 40-46V for inductive load protection. |
| 8 | VOUT | output | High-side switch output pin (one of three parallel pins); RON 50 mΩ at TJ=25°C and 100 mΩ at TJ=150°C, with VDS clamp voltage 40-46V for inductive load protection. |
| 9 | NC | unconnected | No Connect pin; leave floating for normal operation or optionally ground through RPROT resistor if unused. |
| 10 | NC | unconnected | No Connect pin; leave floating for normal operation or optionally ground through RPROT resistor if unused. |
| 11 | NC | unconnected | No Connect pin; leave floating for normal operation or optionally ground through RPROT resistor if unused. |
| 12 | NC | unconnected | No Connect pin; leave floating for normal operation or optionally ground through RPROT resistor if unused. |
| 13 | NC | unconnected | No Connect pin; leave floating for normal operation or optionally ground through RPROT resistor if unused. |
| 14 | SEL1 | input | Multiplexer select input with 350 mV hysteresis; low (SEL1=0) routes load current sense to SNS, high (SEL1=1) routes junction temperature sense to SNS. |
| 15 | NC | unconnected | No Connect pin; leave floating for normal operation or optionally ground through RPROT resistor if unused. |
| 16 | DIA_EN | input | Active-high diagnostic enable input with 350 mV hysteresis; high level enables open-load and short-to-battery detection while switch disabled, allowing analog SNS measurements and fault indication. |
| 17 | VBB | power_in | Positive supply input (exposed thermal pad); nominal operating range 6 V to 18 V (extended range 3 V to 28 V), with VBB clamp 58-76 V for transient protection to 40 V load dump. |
