Product details
Overview
TPS1HB08FQPWPRQ1 from Texas Instruments is a single-channel automotive-grade smart high-side switch designed for 12-V battery systems. It delivers 8-mΩ on-resistance at 25°C, supports 94-A fixed current limiting (Version F), provides analog current/temperature sensing via SNS pin, and integrates thermal shutdown, reverse-battery protection, and inductive-load demagnetization clamp - used in ADAS modules, HVAC control units, and LED headlight drivers.
For engineers reviewing the TPS1HB08FQPWPRQ1 datasheet, TPS1HB08FQPWPRQ1 pinout, TPS1HB08FQPWPRQ1 application, or TPS1HB08FQPWPRQ1 equivalent, key selection criteria include its AEC-Q100 Grade 1 qualification (–40°C to 125°C), HTSSOP-16 package footprint, fault reporting via FLT pin, and compatibility with microcontroller-based load diagnostics and predictive maintenance architectures.
Technical Context
The TPS1HB08FQPWPRQ1 implements a robust integrated power MOSFET with active current-limiting circuitry that disables the channel immediately upon overcurrent detection. Its Version F variant fixes the current limit at 94 A (±11% over –40°C to 60°C), eliminating external resistor programming required by Versions A/B.
Diagnostic functionality is enabled via DIA_EN input and multiplexed through the SNS pin: when SEL1 = 0 V, SNS outputs proportional current sense (KSNS = 5000); when SEL1 = 5 V, it reports device junction temperature. The FLT pin provides open-drain fault indication - active-low during thermal shutdown, overcurrent, open-load, or short-to-battery events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RON (TJ = 25°C) | 8 mΩ - enables low conduction loss and minimal self-heating under 11-A continuous load at 70°C ambient |
| Current Limit | 94 A fixed (Version F) - supports high-transient loads like incandescent bulbs and solenoids without external tuning |
| VBB Range | 6 V to 18 V nominal; withstands 40-V load dump per ISO 16750-2 - ensures operation during automotive cold-crank and alternator transients |
| Sense Accuracy | ±5.3% current sense error at 1–10 A - allows reliable load monitoring and fault classification in safety-critical modules |
| Thermal Shutdown | 150°C with 25°C hysteresis - prevents permanent damage during sustained overload or poor heatsinking |
| Package | HTSSOP-16 (5.0 mm × 4.40 mm) - surface-mount footprint optimized for automotive PCB space constraints and thermal dissipation |
| ESD Rating | HBM ±2000 V (all pins except VBB/VOUT); CDM ±750 V - meets AEC-Q100 ESD stress requirements for vehicle assembly environments |
Pinout & Package
TPS1HB08FQPWPRQ1 is housed in a thermally enhanced HTSSOP-16 (PWP) package with exposed VBB pad for improved heat transfer. Pin 1 is GND; pins 6–11 are paralleled VOUT terminals to reduce trace resistance and enhance current handling.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pin 1) | Power ground reference | Primary return path for load current and internal bias; must be low-impedance connection to system ground plane |
| SNS (Pin 2) | Analog diagnostic output | Multiplexed current/temperature sense signal; requires 1-kΩ pull-down if unused to disable diagnostics |
| LATCH (Pin 3) | Fault-handling mode select | Logic-high enables latched fault shutdown; floating or grounded configures auto-retry behavior |
| EN (Pin 4) | Channel enable input | Active-high TTL-compatible control; internal 1-MΩ pulldown ensures safe-off state at power-up |
| VOUT (Pins 6–11) | High-side switched output | Six paralleled source terminals deliver low RDS(on) and reduced thermal resistance for high-current loads |
| SEL1 (Pin 14) | Diagnostics mode select | Grounded to enable current sense; tied to 5 V for temperature sense - no function in Version F beyond reverse-battery FET turn-on |
| DIA_EN (Pin 16) | Diagnostics activation | Active-high enable for SNS output and open-load/short-to-battery detection; internal pulldown ensures disabled state at startup |
| VBB (Exposed Pad) | Main power supply input | Connects directly to 12-V battery rail; exposed copper pad improves thermal performance and current capacity |
Key Features
| Feature | Design Value |
|---|---|
| 94-A fixed current limit | Eliminates external ILIM resistor and calibration effort while supporting high-peak loads like relays and motors |
| Reverse-battery protection | Automatically turns on internal FET during –18-V reverse events, preventing system damage without external diodes |
| Inductive-load clamp | Integrated clamp dissipates up to 95 mJ during turn-off of 5-mH loads - avoids external flyback components in seat/mirror actuators |
| FLT open-drain fault pin | Direct MCU interrupt signaling for thermal, overcurrent, open-load, and short-to-battery faults - reduces software polling overhead |
| AEC-Q100 Grade 1 | Qualified from –40°C to +125°C ambient - suitable for engine bay, transmission, and front-end ADAS placement |

Equivalent & Alternatives
The following parts are listed as comparable options for similar smart high-side switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS1HB16FQPWPRQ1 | 16-mΩ RON, 160-A fixed current limit, same HTSSOP-16 package | Better suited for higher-power loads (e.g., heated steering wheels, larger fans) requiring >94-A peak capability | Select when load transient currents exceed 94 A or when lower thermal resistance is needed for extended duty cycles |

FAQ
What is the current limit setting for TPS1HB08FQPWPRQ1?
The TPS1HB08FQPWPRQ1 is Version F, which features a fixed 94-A current limit (±11% over –40°C to 60°C). Unlike Versions A/B, it does not require an external resistor on the ILIM pin - simplifying design and eliminating tuning variability. This fixed threshold is optimized for high-transient automotive loads such as headlights and solenoids.
Does TPS1HB08FQPWPRQ1 support reverse-battery protection?
Yes, TPS1HB08FQPWPRQ1 supports reverse-battery protection down to –18 V for up to 3 minutes. During reverse polarity, the device automatically turns on its internal FET to clamp the output and prevent damage to downstream circuitry - eliminating the need for external series diodes in battery-connected applications.
How does the SNS pin function in TPS1HB08FQPWPRQ1?
In TPS1HB08FQPWPRQ1, the SNS pin provides multiplexed analog output: when SEL1 = 0 V, it delivers current-sense signal (ISNS = IOUT / 5000) with ±5.3% accuracy; when SEL1 = 5 V, it reports junction temperature via ISNST. DIA_EN must be high to activate either mode, and the pin requires external 1-kΩ pull-down if unused to ensure safe default behavior.
What fault conditions does the FLT pin indicate on TPS1HB08FQPWPRQ1?
The FLT pin on TPS1HB08FQPWPRQ1 is an open-drain output that pulls low during thermal shutdown, overcurrent (94-A limit exceeded), open-load (VOUT > 3 V with EN high), or short-to-battery (VOUT ≈ VBB with EN low). It remains asserted until the fault clears and EN toggles - enabling direct MCU interrupt-driven diagnostics without polling.
Is TPS1HB08FQPWPRQ1 compatible with standard HTSSOP-16 PCB footprints?
Yes, TPS1HB08FQPWPRQ1 uses the industry-standard HTSSOP-16 (PWP) package with 5.0 mm × 4.40 mm body size and 0.65-mm lead pitch. Its exposed VBB pad aligns with JEDEC MO-153 guidelines, and thermal vias under the pad are recommended to achieve the specified RθJB = 9.2°C/W - ensuring compatibility with existing automotive PCB layouts.
