Product details

Overview

VN7004CHTR 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-enabling robust control of glow plugs, heating systems, and DC motors in harsh vehicle environments.

For engineers reviewing the VN7004CHTR datasheet, VN7004CHTR pinout, VN7004CHTR application, or VN7004CHTR equivalent, key selection criteria include its Octapak thermal performance, CS pin analog sensing linearity (K₁ = 16.7 kA/A typ), SEn-controlled OFF-state diagnosis, and integrated protections against reverse battery, overvoltage, and thermal shutdown.

Technical Context

This device implements VIPower® M0-3 technology to integrate power MOSFET, protection logic, and diagnostic circuitry in one monolithic die. Its high-side architecture enables direct connection between battery (VCC) and load, while the CurrentSense (CS) output delivers a proportional current (I_SENSE = I_OUT/K₁) with ±20% ratio drift over temperature and load.

The SEn pin enables/disables CS functionality during low-power states, supporting shared external sense resistors across multiple channels. Protection mechanisms include active power limitation during overload, dynamic thermal shutdown at 150 °C, and open-load detection in OFF-state via voltage threshold monitoring at the OUTPUT pin.

Key Specifications

Parameter	Value and Actual Design Meaning
VCC Range	4–28 V operating; supports cold-crank (4 V) and load-dump (40 V transient) conditions in automotive 12 V systems
R_ON	4 mΩ typ @ 15 A, 25 °C - enables <1 W conduction loss at 15 A, reducing heatsink requirements
I_LIMH	135 A typ DC short-circuit current limit - sustains brief high-current faults without latch-off
I_STBY	0.5 µA max @ 13 V, 25 °C - minimizes parasitic drain in always-on vehicle modules
CS Sensing Ratio	K₁ = 16.7 kA/A typ @ 10 A - delivers ~600 µA I_SENSE for 10 A load, compatible with standard ADC inputs
T_J Range	−40 to +150 °C junction operation - meets under-hood thermal requirements per AEC-Q100 Grade 0
R_thj-case	1.45 °C/W - enables efficient heat transfer to PCB copper when mounted on 4-layer board with 2s2p layout

Pinout & Package

The VN7004CHTR is housed in the Octapak package-a thermally enhanced, surface-mount power package with exposed metal top for direct heatsinking and optimized PCB copper area coupling.

Pin/Terminal	Circuit Role	Design Meaning
VCC	Battery supply input	Accepts 4–28 V DC; clamped to 40 V during ISO 7637-2 Pulse 5b transients
OUTPUT	High-side power output	Single switched node connecting to load; all OUTPUT pins internally bonded and must be externally tied together
GND	Power ground reference	Low-inductance return path for load current and internal diagnostics; separate from logic ground
INPUT	CMOS-compatible control input	Hysteresis-enabled (0.2 V), accepts 3 V/5 V logic; drives internal power stage directly
CS	Analog current sense output	Current-source output (I_SENSE = I_OUT/K₁); requires external pull-up resistor for voltage conversion
SEn	Sense enable control	Active-high CMOS input; disables CS output and OFF-state diagnostics when low

Key Features

Feature	Design Value
Integrated CurrentSense with K₁ calibration	16.7 kA/A typical gain with ±20% drift over −40 to +150 °C - enables accurate closed-loop current monitoring without external shunt
OFF-state open-load detection	Monitors OUTPUT pin voltage during INPUT = LOW; triggers diagnostic if >2.5 V - detects disconnected loads before activation
Reverse battery protection	Withstands −16 V applied to VCC with R_{ON_rev} = 4 mΩ - eliminates need for external series diode in battery-reversal-prone systems
Dynamic thermal management	Self-limiting fast thermal transients via power limitation, plus hard shutdown at 150 °C - prevents cumulative SOA violation during pulsed loads
Undervoltage lockout with hysteresis	Shuts down at VCC < 4 V, re-enables at 4.3 V - avoids erratic switching during cranking or brown-out conditions

Applications

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
INFINEON BTS7004-1EPP	Higher R_ON (6 mΩ), no analog CS output - uses digital fault flag only	Lacks continuous current telemetry; suitable for binary ON/OFF loads without regulation needs	Select when cost sensitivity outweighs need for closed-loop current control
NXP MC33883	Lower current limit (60 A), SPI-configurable protections, but requires external gate driver and sense resistor	Offers programmable diagnostics via serial interface; better for multi-channel coordinated systems	Select when system-level configurability and channel synchronization are prioritized over integration density

Compared with VN7004CHTR, BTS7004-1EPP trades analog sensing for lower unit cost and simpler layout, while MC33883 adds flexibility at the expense of higher component count and design complexity - making VN7004CHTR optimal for cost-constrained, single-channel automotive actuators requiring embedded current visibility.

FAQ

What is the purpose of the SEn pin on VN7004CHTR?

The SEn (Sense Enable) pin is an active-high CMOS input that controls whether the CurrentSense (CS) output is active. When SEn = LOW, CS is disabled and OFF-state diagnostics (e.g., open-load detection) are suppressed - allowing the device to enter ultra-low-power standby mode without erroneous fault signals. This feature supports shared external sense resistors across multiple VN7004CHTR devices in modular designs.

How does VN7004CHTR handle reverse battery conditions?

VN7004CHTR withstands −16 V applied to VCC with no damage and maintains R_{ON_rev} = 4 mΩ at −15 A, enabling direct connection to vehicle battery without external reverse-polarity protection diodes. Its internal structure blocks reverse current flow through the power MOSFET body diode while preserving functional integrity - verified per AEC-Q100 stress testing and widely deployed in starter motor and lighting control modules.

Can VN7004CHTR drive inductive loads like DC motors without external flyback components?

Yes - VN7004CHTR integrates an active clamp that limits turn-off voltage spikes to VCC − 41 V (typ) during inductive kickback, validated with 6 mH loads and 2 A current. This eliminates the need for external TVS or freewheeling diodes in most 12 V automotive motor applications, though PCB layout must maintain low-inductance GND paths to ensure clamp effectiveness under fast dI/dt conditions.

What is the accuracy of the CurrentSense function across temperature and load?

The CS output exhibits ±20% full-scale error in current-sense ratio (dK/K) over −40 to +150 °C and 0–15 A load range, with K₁ = 16.7 kA/A typical at 10 A. This corresponds to ~±2 mA absolute error in I_SENSE at 10 A - sufficient for overcurrent detection and thermal derating, but not for precision metering. Calibration at system level improves accuracy to ±3% using a single-point offset/gain trim.
