Product details

Overview

VN7004SLHTR from STMicroelectronics is a single-channel automotive smart high-side driver in Octapak package, designed for 12 V grounded loads with 3 V/5 V CMOS-compatible control, 4 mΩ on-state resistance, 135 A current limit, and analog CurrentSense feedback. It delivers precise load control and diagnostics in automotive seat heating systems.

For engineers reviewing the VN7004SLHTR datasheet, VN7004SLHTR pinout, VN7004SLHTR application, or VN7004SLHTR equivalent, key selection criteria include AEC-Q100 qualification, OFF-state open-load detection, configurable latch-off on overtemperature, reverse battery protection, and ±0.5 µA standby current at 13 V.

Technical Context

This device implements VIPower M0-7 technology with integrated power MOSFET, thermal shutdown (TTSD = 175 °C), and dynamic power limitation via spatial temperature gradient sensing (ΔTj_SD = 60 K). Protection logic is controlled by FR_DIAG pin state to enable auto-restart or latch-off modes.

The CurrentSense (CS) output provides analog current feedback with K-factor ranging from 9,000 to 24,500 A/A across 1–45 A load range, calibrated precision ≤±10% at 45 A, and fault indication via VSENSEH = 5–6.6 V during overload or short-to-ground events.

Key Specifications

Parameter	Value and Actual Design Meaning
VCC Range	4–28 V DC operating supply; supports wide automotive battery variation including cold-crank (4 V) and load-dump transients.
R_ON	4 mΩ typ. at 15 A, 25°C; enables <150 mW conduction loss at 15 A, critical for thermally constrained seat heater PCBs.
I_LIMH	135 A typ. DC short-circuit current limit; protects bonding wires, harness, and heater elements during fault conditions.
I_STBY	0.5 µA max. at 13 V, 25°C; ensures negligible battery drain in parked vehicle mode over multi-year service life.
CurrentSense K-Factor	16,650 A/A typ. at I_OUT = 1 A; enables accurate real-time load monitoring with <±10% uncalibrated error up to 45 A.
T_J Operating Range	−40 to +150 °C junction temperature; validated for under-seat mounting with high ambient thermal stress.
ESD Rating	4 kV HBM on INPUT, FR_DIAG, OUTPUT, VCC; meets automotive system-level robustness requirements without external TVS.

Pinout & Package

Package: Octapak - thermally enhanced power package with integrated heatsink tab (VCC-connected), optimized for high-current automotive applications requiring low R_thj-case = 1.45 °C/W.

Pin/Terminal	Circuit Role	Design Meaning
VCC	Battery supply input	Primary power rail connection; also serves as thermal pad (Tab); clamped to 40 V transient per ISO 7637-2 Pulse 5b.
OUTPUT	Power output terminal	High-side switch output; all three OUTPUT pins must be paralleled to handle full 135 A current path.
GND	Ground reference	Logic and power ground return; internal protection includes loss-of-GND detection.
INPUT	Digital control input	CMOS-compatible (3 V/5 V) with 0.2 V hysteresis; controls ON/OFF state of output MOSFET.
CS	Analog current sense output	Current-source output proportional to load current (I_SENSE = I_OUT/K); used for closed-loop thermal management.
FR_DIAG	Functional reset & diagnostic mode select	Configures fault response: Low = auto-restart, High = latch-off; enables OFF-state open-load detection when High.

Key Features

Feature	Design Value
Integrated reverse battery protection	Operates safely with −13 V VCC; no external components required; maintains 4 mΩ R_ON even in reverse polarity.
Dynamic power limitation	Shuts off output when ΔT_j exceeds 60 K; prevents thermo-mechanical fatigue during fast thermal transients.
OFF-state open-load detection	Validated at VOL = 2–4 V threshold with 400–2500 µs delay; enables heater element continuity check before activation.
Short-to-VCC detection	Identifies output shorted to battery rail during OFF state using internal voltage comparator; reported via CS pin.
AEC-Q100 Grade 0 qualification	Rated for −40 to +150 °C operation; qualified per stress test requirements for safety-critical automotive cabin systems.

Applications

12 V Cabin Lighting Management

Use Scenario: Precise PWM-controlled heating element drive in front/rear seats with real-time temperature feedback loop.

IC Role / Device Role / Timing Role: High-side power switch with analog current feedback and thermal derating coordination via CS pin.

Use Value: Enables closed-loop thermal regulation using measured I_OUT to dynamically adjust duty cycle and prevent overheating or element burnout.

Use Scenario: Switching LED arrays or incandescent bulbs in door panels, footwells, and map lights.

IC Role / Device Role / Timing Role: Robust high-side driver with short-circuit and open-load diagnostics for fail-safe illumination control.

Use Value: Eliminates need for discrete fuses and external current-sense resistors; reduces BOM count while enabling bulb-out detection.

Electric Parking Brake Actuator Interface

Heated Windshield Demister Zone Control

Use Scenario: Driving solenoid-based parking brake actuators requiring controlled inrush and stall current limiting.

IC Role / Device Role / Timing Role: Smart high-side switch with 135 A peak current capability and fast thermal shutdown (175 °C).

Use Value: Prevents coil burnout during extended hold states; diagnostic feedback allows ECU to distinguish between mechanical jam and electrical fault.

Use Scenario: Segmented heating zones on windshield glass with independent thermal monitoring per zone.

IC Role / Device Role / Timing Role: Zone-specific high-side driver with CurrentSense feedback for localized power adjustment.

Use Value: Enables adaptive de-icing by scaling zone power based on real-time current draw, improving energy efficiency and defrost speed.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-side driver applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TPS27081AQPWPRQ1	Lower current limit (8 A), no analog current sense, only digital fault flag; SOIC-8 package.	Suitable for low-power lighting or sensor biasing-not for >10 A resistive loads like heaters.	Select only for space-constrained, low-current diagnostics where analog feedback is unnecessary.
IPS1025H	Higher R_ON (12 mΩ), same Octapak package, 120 A current limit, no OFF-state open-load detection.	Lacks VOL-based open-load test; requires external circuitry for heater continuity verification pre-activation.	Choose if thermal performance margin is acceptable and diagnostic depth is reduced to basic overcurrent/thermal flags.

Compared with VN7004SLHTR, TPS27081AQPWPRQ1 lacks current-sense capability and thermal cycling robustness, while IPS1025H trades sensing fidelity and diagnostic completeness for slightly lower cost-neither matches the integrated OFF-state diagnostics and 4 mΩ conduction efficiency required for seat heater reliability.

FAQ

What is the purpose of the FR_DIAG pin?

The FR_DIAG pin configures fault-handling behavior: logic low enables auto-restart after thermal or overload shutdown, while logic high forces latch-off until manual reset. It also enables OFF-state open-load detection and disables current sense during fault conditions per truth table Mode definitions.

How does the device achieve reverse battery protection without external components?

VN7004SLHTR integrates internal protection structures-including reverse-biased diodes and clamp networks-that allow safe operation down to −13 V VCC. The output MOSFET remains functional in reverse polarity, maintaining low R_ON (4 mΩ) and eliminating need for external diodes or fuses.

Can the CurrentSense (CS) pin be used for closed-loop thermal control?

Yes. The CS pin delivers a current (I_SENSE = I_OUT/K) linearly proportional to load current across 1–45 A. With known heater resistance and ambient thermal model, MCU can derive real-time power dissipation and modulate PWM to maintain safe surface temperature.

What is the maximum transient voltage the device withstands on VCC?

VN7004SLHTR sustains up to +40 V transient on VCC per ISO 7637-2 Pulse 5b Level IV (clamped), verified with 4 Ω line impedance. This covers automotive load-dump events without external clamping, supporting 12 V system robustness in modern vehicles.
