Product details

Overview

VN7004CLHTR from STMicroelectronics is a single-channel automotive-grade smart high-side driver with analog current sense feedback, designed for 12 V grounded loads. It features 4 mΩ typical on-state resistance, 135 A current limitation, 4–28 V operating supply range, and AEC-Q100 qualification. Used in glow plug control, heating systems, and DC motor drive where precise load monitoring and fault diagnostics are critical.

For engineers reviewing the VN7004CLHTR datasheet, VN7004CLHTR pinout, VN7004CLHTR application, or VN7004CLHTR equivalent, this page delivers verified electrical specs, diagnostic behavior, thermal performance on PCB, protection thresholds, and real-world use cases in automotive power distribution.

Technical Context

The VN7004CLHTR integrates VIPower® technology to combine power MOSFET switching with embedded protection logic and analog current sensing. Its INPUT pin accepts 3 V/5 V CMOS-compatible signals, while FR_DIAG configures latch-off behavior and enables OFF-state diagnostics including open-load and short-to-VCC detection.

CurrentSense (CS) provides a proportional output current (K₀ = 9–24.5 kA/A typ.) referenced to GND, enabling real-time load current monitoring without shunt resistors. Protection functions include undervoltage shutdown (V_USD = 4 V), overvoltage clamp (up to 46 V), thermal shutdown (T_TSD = 150–200 °C), and self-limiting during fast thermal transients.

Key Specifications

Parameter	Value and Actual Design Meaning
Operating Voltage Range	4–28 V DC - supports full automotive battery range including cold-crank (4 V) and load-dump (28 V)
On-State Resistance (R_ON)	4 mΩ typ. at 15 A, 25°C - minimizes conduction loss and heat generation in high-current paths
Current Limit Threshold	135 A typ. - protects against sustained overload and short-circuit faults in inductive loads
Standby Current	0.5 µA max. at 25°C - enables ultra-low-power sleep mode for always-on vehicle subsystems
Current Sense Ratio (K₀)	9–24.5 kA/A - delivers scalable analog I_OUT/I_SENSE scaling for MCU ADC interfacing
Thermal Shutdown Temp	150–200 °C - triggers automatic output disable before junction damage occurs
AEC-Q100 Qualification	Qualified per Grade 0 (−40 to +150°C) - validated for under-hood automotive environments

Pinout & Package

The VN7004CLHTR is housed in the Octapak package - a thermally enhanced, surface-mount power package with integrated heatsink pad and optimized copper layout for high-current automotive applications.

Pin/Terminal	Circuit Role	Design Meaning
VCC	Battery supply input	Accepts 4–28 V DC; clamped to 40 V transient; powers internal logic and gate driver
OUTPUT	Power output terminal	Single high-side switch output; all OUTPUT pins must be connected together for parallel current handling
GND	Ground reference	Common return path for logic, sense, and power sections; critical for CS accuracy and ESD robustness
INPUT	Digital control input	CMOS-compatible (3 V/5 V); includes 0.2 V hysteresis to reject noise in automotive environments
CS	Analog current sense output	Delivers I_SENSE ∝ I_OUT; enables real-time load monitoring without external shunt resistor
FR_DIAG	Diagnostic configuration & fault reset	Configures latch-off behavior; enables OFF-state diagnostics (open-load, short-to-VCC)

Key Features

Feature	Design Value
Integrated CurrentSense analog feedback	Eliminates need for external shunt resistor and signal conditioning circuitry; reduces BOM count and PCB area
Configurable latch-off on fault	FR_DIAG pin allows system-level decision to auto-restart or hold latched state after overtemperature or overload
OFF-state open-load and short-to-VCC detection	Enables pre-activation verification of load integrity - critical for safety-critical actuators like glow plugs
Reverse battery protection	Withstands −16 V reverse supply without damage; supports robust vehicle service conditions
Ultra-low standby current (0.5 µA)	Meets automotive "always-on" module requirements without compromising battery life during extended parking

Applications

Glow Plug Control

Heating System Actuation

Use Scenario: Precise timing and current-controlled energizing of diesel engine glow plugs during cold start.

IC Role / Device Role / Timing Role: High-side driver with real-time current feedback ensures correct pre-heating duration and detects open-circuit or shorted plug elements.

Use Value: Prevents engine misfire by validating load integrity before activation and limiting inrush current to avoid fuse blow.

Use Scenario: Driving PTC heaters in cabin HVAC or battery thermal management systems.

IC Role / Device Role / Timing Role: Power switch with thermal foldback and current monitoring enables closed-loop temperature regulation via PWM duty cycle adjustment.

Use Value: Maintains heater reliability across wide ambient temperatures while detecting degraded elements before thermal runaway.

DC Motor Drive (Fan/Blower)

Relay Replacement in Body Control Modules

Use Scenario: Controlling brushed DC fans in engine cooling or cabin air circulation systems.

IC Role / Device Role / Timing Role: High-current switching element with inductive flyback energy management and stall detection via current sense.

Use Value: Replaces electromechanical relays with faster response, no contact wear, and built-in stall/fault reporting to MCU.

Use Scenario: Solid-state replacement of 12 V relays controlling lights, locks, or window motors in BCMs.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
INFINEON BTS7004-1EPP	4.5 mΩ R_ON, 120 A ILIM, no analog CS - uses digital current flag only	Lacks continuous analog current feedback; requires external ADC or shunt for precise measurement	Select when discrete fault flag suffices and analog sensing is not required
NXP MC33883HPDW	5.5 mΩ R_ON, 100 A ILIM, SPI-configurable diagnostics, no integrated CS amplifier	Requires external op-amp for current sense signal conditioning; offers programmable protection thresholds	Choose for systems needing field-upgradable protection settings via serial interface

Compared with VN7004CLHTR, BTS7004-1EPP trades analog current sense for lower R_ON tolerance and simpler diagnostics, while MC33883HPDW adds configurability at the cost of external signal conditioning - making VN7004CLHTR optimal for cost-sensitive, analog-feedback-dependent automotive actuators.

FAQ

What is the maximum transient voltage the VN7004CLHTR can withstand?

The VN7004CLHTR supports up to 40 V transient supply voltage per ISO 7637-2 Pulse 5b Level IV, clamped internally. This rating applies under specified test conditions (R_L = 4 Ω) and ensures reliable operation during automotive load-dump events without external TVS diodes.

How does the CurrentSense (CS) pin function during OFF-state diagnostics?

With FR_DIAG asserted, the CS pin enables OFF-state open-load and short-to-VCC detection by measuring leakage current and output voltage levels. In open-load condition, CS outputs near 0 V; in short-to-VCC, it rises above threshold - allowing MCU-based validation before activation.

Can the VN7004CLHTR drive inductive loads without external flyback components?

Yes - the device integrates an active clamp that limits turn-off voltage spikes to V_CC − 38 V (min) during inductive demagnetization. This eliminates need for external freewheeling diodes in most 12 V automotive inductive loads up to 6 mH.

What thermal derating guidance applies when using VN7004CLHTR on a 2-layer PCB?

On a 2-layer JEDEC JESD 51-5 board with 2 cm² heatsink copper, R_thj-amb = 58.1 °C/W. At 150°C max junction temperature and 85°C ambient, max continuous power dissipation is ~1.1 W - corresponding to ~16 A at 4 mΩ R_ON. Larger copper area or forced airflow significantly improves capability.
