TPS2HB16-Q1

Dual-channel 16mΩ diagnostic high-side switch

Combines two 12V load switches and multiplexed analog diagnostics in one package for paired lamps or zone-controller outputs. Channels are separately controlled but share the package and board thermal budget. Do not simply double a single-channel capability or read the F variant's 60A inrush-oriented threshold as continuous current per channel.

LifecycleActive

In one sentence: Qualification is grounded in this TI product's documentation; no grade is inferred from temperature. An ordering table may show junction or variant-specific limits, which must be distinguished from ambient conditions. No TI functional-safety category was established in the reviewed product parameters/features. This does not prove that related documents are unavailable; do not infer ASIL or Compliant status.

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.

FAQ

Can two high current-limit settings be treated as twice the continuous current?

No. 4.1–22A, 10.3–48.5A and 60A describe A/B/F overcurrent thresholds. Both channels' losses enter the same package and PCB. Thermal shutdown is channel-specific, but that does not give the channels thermally independent power budgets.

Can it be relied on to disconnect the load during reverse battery?

Reverse-battery protection is not blocking. The switch turns on automatically under reverse voltage, requiring the datasheet's ground and I/O protection network and a separate check of load reverse tolerance. The 40V load-dump capability does not change the 6–18V nominal supply range.

How should I verify the TPS2HB16-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.
