TPS1H100AQPWPRQ1 is a Texas Instruments TPS1H100-Q1 automotive single-channel high-side power switch in 14-pin HTSSOP, tape and reel — AEC-Q100 qualified, 5 V to 40 V load voltage, 4 A output with 80 milliohm typical on-resistance, adjustable current limit, open-load detection, over-temperature shutdown, UVLO and a fault status flag, −40 °C to +125 °C. The Q1 code is the selection point: the automotive-qualified smart switch for driving lamps, relays, solenoids and resistive loads with full diagnostics back to the MCU. Selection advice: the value over a discrete MOSFET plus fuse is the protection stack — adjustable current limit, thermal shutdown and open-load detection are built in, which is exactly what automotive load control requires and what a bare FET cannot give. The 80 milliohm Rds(on) keeps dissipation low at 4 A; the status flag lets the MCU distinguish overload from open load. The QPWP HTSSOP-14 gives a thermal pad for the power path. Evidence: TI and distributor data confirm AEC-Q100, 5–40 V, 4 A, 80 milliohm, adjustable current limit and HTSSOP-14. Match the full TPS1H100AQPWPRQ1 code.
Ordering-code highlights reviewed against official manufacturer documentation.
TPS1H100-Q1 is available in the following manufacturer order codes. They share the same TPS1H100-Q1 design; the table highlights package, packing and ordering differences. Quote the exact code your BOM needs.
| Order code | Package | Packing | Key difference |
|---|---|---|---|
| TPS1H100AQPWPRQ1 | HTSSOP-14 | LARGE T&R | Version A provides open-drain status output; the on-site Version B provides analog current-sense output — the diagnostic interface circuit requires redesign and cannot be treated as a functional drop-in; same HTSSOP-14 package as TPS1H100BQPWPRQ1; this difference alone does not require PCB pad changes. |

Browse existing catalog records — same series first, then the same category and manufacturer. These are not confirmed replacements; compatibility requires engineering review.
These are order-code variants of the same Texas Instruments series. They share the core design; the ordering code selects the exact configuration — TPS1H100BQPWPRQ1 (HTSSOP-14). TPS1H100AQPWPRQ1 itself is the HTSSOP-14 configuration. A code that differs by even one character may be a different device, so always quote the complete code exactly as it appears on your BOM.
The TPS1H100AQPWPRQ1 ordering code carries the manufacturer's automotive qualification marker. Qualification grade, temperature range and PPAP documentation depend on the exact lot offered, so state your automotive documentation requirements (PPAP level, AEC test reports) in the RFQ and we will confirm them against the offered lot before quotation.
From the verified technical profile: Package code: HTSSOP (PWP); Pin count: 14; Operating temperature: -40 to 125 °C. These are the catalog-recorded values for TPS1H100AQPWPRQ1 — always re-check them against the manufacturer datasheet revision quoted on your BOM before finalizing the design.
