TPS1HB16-Q1
Single-channel 16mΩ high-side switch with analog diagnostics
Switches one protected 12V body load and reports load current or device temperature through SNS. A/B/F variants select programmable or fixed current-limit thresholds, not continuous-current ratings. Choose the variant against lamp inrush, harness fault protection and PCB heat dissipation together.

Key specifications
Orderable variants (OPNs)
The GPN is for selection; the full OPN is for ordering. These examples were observed on the verification date, not live stock. Variants may differ in package, temperature, gain/threshold and, for PMICs, NVM/sequencing. Distinguish TA from TJ in the exact datasheet.
| OPN | Package | Temperature | Note |
|---|---|---|---|
| TPS1HB16AQPWPRQ1 | HTSSOP (PWP) · 16 pin | -40 to +125°C (TI OPN listing; verify TA/TJ) | Verify exact OPN, temperature definition and revision; not a stock claim. |
| TPS1HB16BQPWPRQ1 | HTSSOP (PWP) · 16 pin | -40 to +125°C (TI OPN listing; verify TA/TJ) | Verify exact OPN, temperature definition and revision; not a stock claim. |
| TPS1HB16FQPWPRQ1 | HTSSOP (PWP) · 16 pin | -40 to +125°C (TI OPN listing; verify TA/TJ) | Verify exact OPN, temperature definition and revision; not a stock claim. |

FAQ
Does the F variant's 60A limit mean it can supply 60A continuously?
No. 60A is an internally fixed overcurrent threshold; the A/B ranges are also limit settings, not rated load currents. Continuous capability depends on hot on-resistance, package/PCB thermal resistance, ambient temperature and duty cycle. Likewise, 40V describes load-dump withstand, not nominal continuous supply.
Does reverse-battery protection block reverse current?
Do not infer blocking. Under reverse voltage the device automatically turns on the power FET to reduce dissipation; it is not a reverse-current-blocking switch. Follow the reverse-battery ground/I/O protection circuit and check the load's reverse-voltage tolerance.
How should I verify the TPS1HB16-Q1 orderable?
The page lists 3 OPN examples from official material checked on 2026-11-06. Match package, function options and temperature definitions; obtain live price/stock from TI or authorized distributors.
