Product details
Overview
TPS1HB08AQPWPRQ1 from Texas Instruments is a single-channel AEC-Q100 Grade 1 smart high-side switch for 12-V automotive systems, featuring 8-mΩ RON (TJ = 25°C), resistor-programmable current limit (6.4 A to 32 A), integrated thermal shutdown, reverse-battery protection with automatic FET turn-on, and analog current/temperature sense via SNS pin. It drives incandescent/LED lighting, relays, and inductive loads in body control modules.
For engineers reviewing the TPS1HB08AQPWPRQ1 datasheet, TPS1HB08AQPWPRQ1 pinout, TPS1HB08AQPWPRQ1 application, or TPS1HB08AQPWPRQ1 equivalent, this page delivers verified technical context, exact pin functions, real-world diagnostic use cases, and validated alternative parts - all grounded in TI's SLVSE16C production data sheet (Rev C, Jan 2020).
Technical Context
The TPS1HB08AQPWPRQ1 implements a robust N-channel MOSFET high-side architecture with integrated gate driver, current-sense amplifier, and fault management logic. Its programmable ILIM pin sets overcurrent threshold via external resistor, while SEL1 and DIA_EN enable multiplexed analog sensing of load current (IOUT/ISNS = 5000) or junction temperature (ISNS,T = 0.72–2.31 mA across –40°C to 150°C).
Fault handling is configurable via LATCH pin: latched shutdown or auto-retry mode. Protection includes short-to-ground/battery detection, open-load sensing (2–4 V threshold), demagnetization clamp for inductive loads, and 40-V load dump tolerance per ISO 16750-2. The device operates from 3 V to 28 V VBB and supports diagnostic PWM timing with tSNSION1 ≤ 40 µs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RON | 8 mΩ at TJ = 25°C; enables low conduction loss (≤1.02 W at 11 A) and minimal self-heating in high-current automotive loads. |
| Current Limit Range | 6.4 A to 32 A (Version A); set by resistor on ILIM pin - allows precise matching to load transient profiles without oversizing. |
| VBB Range | 3 V to 28 V; supports cold-crank (3 V) and load-dump (40 V transient) conditions in 12-V vehicle electrical systems. |
| Current Sense Accuracy | ±5.3% error at IOUT = 10 A; enables reliable predictive maintenance and closed-loop load monitoring via MCU ADC. |
| Thermal Shutdown | 150°C with 20–30°C hysteresis; prevents permanent damage during sustained overload or poor heatsinking. |
| Diagnostic Timing | tSNSION1 ≤ 40 µs; ensures fast current-sense settling for real-time fault response in safety-critical ADAS subsystems. |
| AEC-Q100 Grade | Grade 1 (–40°C to +125°C ambient); qualified for under-hood and cabin applications including HVAC and transmission control units. |
Pinout & Package
TPS1HB08AQPWPRQ1 is housed in a thermally enhanced HTSSOP-16 (PWP) package (5.0 mm × 4.40 mm), with exposed VBB pad for improved power dissipation and PCB-level thermal management.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pin 1) | Reference ground | Primary return path for internal circuitry and sense amplifier; must be low-impedance connection to system GND plane. |
| SNS (Pin 2) | Analog sense output | Provides proportional current (ISNS = IOUT/5000) or temperature signal; requires 1-kΩ pull-down if unused. |
| LATCH (Pin 3) | Fault behavior control | High = latched shutdown; low/floating = auto-retry; enables system-level fault recovery strategy selection. |
| EN (Pin 4) | Enable input | Active-high logic control (VIH = 2.0 V min); internal 0.5–2 MΩ pulldown ensures safe default-off state. |
| ILIM (Pin 5) | Current limit programming | Resistor-to-GND sets threshold (6.4–32 A); floating defaults to 42 A - treated as fault condition. |
| VOUT (Pins 6–11) | Power output channel | Parallel pins reduce trace resistance and inductance; rated for continuous 11 A at TAMB = 70°C. |
| SEL1 (Pin 14) | Sense mode select | Low = current sense; high = temperature sense; must be grounded via RPROT for reverse-battery FET turn-on. |
| DIA_EN (Pin 16) | Diagnostic enable | Active-high enable for SNS functionality; floating disables diagnostics including open-load and short-to-battery detection. |
| VBB (Exposed Pad) | Main power supply input | Connects directly to battery rail; large copper area required for thermal and current handling (supports 40-V transients). |
Key Features
| Feature | Design Value |
|---|---|
| Adjustable current limiting | 6.4 A to 32 A range via single external resistor - eliminates need for multiple BOM variants across load types. |
| Reverse battery protection | Automatic FET turn-on at –8 V to –18 V VBB; sustains load operation during reverse jump-start without external diodes. |
| Integrated demagnetization clamp | Clamps VOUT to 40–46 V during inductive turn-off; protects downstream components when driving relays/motors. |
| High-accuracy analog sense | ±5.3% current sense error and <0.0112 mA/°C temp coefficient enable MCU-based thermal derating and load health analytics. |
| Configurable fault reporting | SNS pin reports open-load (2–4 V), short-to-battery, and thermal faults; FLT pin (Version F only) provides open-drain fault flag. |
| AEC-Q100 Grade 1 qualification | Validated for –40°C to +125°C operation with HBM ±2 kV / CDM ±750 V ESD rating - meets automotive reliability requirements. |

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 |
|---|---|---|---|
| TPS1HB16AQPWPRQ1 | 16-mΩ RON, 4.5–16 A current limit range; identical pinout and feature set. | Better suited for lower-power loads (e.g., small solenoids, indicator LEDs) where thermal margin is less critical. | Select when peak load current ≤12 A and board space constraints favor reuse of same footprint. |
| TPS2HB35-Q1 | 35-mΩ RON, fixed 5-A current limit, no analog sense output; QFN-20 package. | Targeted at cost-sensitive, non-diagnostic applications like seat heater control where only basic overcurrent protection is needed. | Choose when diagnostics are unnecessary and BOM simplification outweighs higher conduction loss and lack of temperature sensing. |
Compared with TPS1HB08AQPWPRQ1, TPS1HB16AQPWPRQ1 offers lower thermal stress at moderate currents but reduced drive capability, while TPS2HB35-Q1 sacrifices sensing and programmability for lower unit cost and smaller QFN footprint - making each suitable for distinct tiers of automotive functional safety requirements.

FAQ
What is the maximum continuous load current supported by the TPS1HB08AQPWPRQ1?
The TPS1HB08AQPWPRQ1 supports 11 A continuous load current at TAMB = 70°C with proper PCB thermal design. This rating assumes use of the exposed VBB pad with ≥4 cm² copper area and 2 oz copper layers. At higher ambient temperatures or reduced copper, derating applies per RθJA = 32.6°C/W.
How does the TPS1HB08AQPWPRQ1 handle reverse battery conditions?
The TPS1HB08AQPWPRQ1 automatically turns on its internal FET during reverse battery events (–8 V to –18 V), allowing current flow to sustain connected loads. This eliminates the need for external reverse-polarity protection diodes and maintains system functionality during improper jump-start attempts.
Can the TPS1HB08AQPWPRQ1 be used without connecting the SEL1 pin?
Yes, but SEL1 must be grounded through an RPROT resistor (typically 10 kΩ) if unused. Leaving SEL1 floating disables reverse-battery FET turn-on and restricts diagnostics to current sensing only - temperature sensing and full fault coverage require proper SEL1 biasing.
What is the purpose of the ILIM pin on the TPS1HB08AQPWPRQ1, and what happens if it is left unconnected?
The ILIM pin sets the overcurrent threshold via an external resistor to GND. If left floating, the TPS1HB08AQPWPRQ1 defaults to 42 A - a value outside the intended 6.4–32 A range and treated as a fault state, causing immediate disablement upon enable. Always terminate ILIM with appropriate resistor or GND.
Does the TPS1HB08AQPWPRQ1 provide open-load detection, and how is it implemented?
Yes, the TPS1HB08AQPWPRQ1 detects open loads via its SNS pin, generating a 2–4 V signal when VOUT rises above threshold with EN active and no load current. This occurs within 300–700 µs of EN deactivation and is enabled only when DIA_EN is high and SEL1 is low - enabling reliable bulb-out detection in lighting modules.
