Product details
Overview
VN7004CH from STMicroelectronics is a single-channel automotive-grade smart high-side driver with analog CurrentSense 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 VN7004CH datasheet, VN7004CH pinout, VN7004CH application, or VN7004CH equivalent, key selection criteria include its integrated open-load/short-to-VCC diagnostics, ultra-low 0.5 µA standby current, 40 V transient voltage tolerance, and CMOS-compatible 3 V/5 V input interface for MCU integration.
Technical Context
The VN7004CH implements VIPower® technology to integrate power MOSFET, protection logic, and analog current-sensing in a single die. Its diagnostic architecture supports OFF-state open-load detection via CS pin voltage thresholds and active power limitation during overload, with thermal shutdown triggered at 150 °C and hysteresis reset at ~143 °C.
It delivers precise analog current feedback (K₁ = 16.7 kA/A typ.) with ±20% ratio drift over temperature, while maintaining safe operation under reverse battery (−13 V), ISO 7637-2 Pulse 5b transients (40 V clamped), and loss-of-ground/VCC conditions-critical for ASIL-B–compatible power distribution modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 4–28 V operating supply; supports full automotive battery range including cold-crank (4 V) and load-dump (28 V) |
| RON | 4 mΩ typ. @ 15 A, 25 °C; enables <1 W conduction loss at 15 A, reducing heatsink requirements |
| ILIMH | 135 A typ. DC short-circuit current limit; self-regulates power dissipation during sustained overload |
| ISTBY | 0.5 µA max. @ 13 V, 25 °C; minimizes parasitic drain in always-on vehicle modules |
| CurrentSense Gain | K₁ = 16.7 kA/A typ.; delivers 1 mA output per ~60 mA load current for accurate external ADC sampling |
| TJ Operating Range | −40 to +150 °C junction temperature; validated for under-hood placement without derating |
| AEC-Q100 Grade | Grade 0 (−40 to +150 °C); qualified per stress test requirements for safety-critical automotive functions |
Pinout & Package
Housed in the Octapak package-a thermally enhanced, surface-mount power package with integrated heatsink pad and isolated power/ground terminals-the VN7004CH provides low Rthj-case (1.45 °C/W) for high-current operation without external heatsinks in standard PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Battery supply input | Accepts 4–28 V DC; clamps transients up to 40 V; reverse-battery tolerant to −16 V |
| OUTPUT | High-side power output | Single switched terminal connecting to load; all OUTPUT pins internally bonded and must be paralleled externally |
| GND | Power ground reference | Low-impedance return path; loss-of-ground detection enabled; supports reverse-battery protection |
| INPUT | CMOS-compatible enable input | Hysteresis-enabled (0.2 V), compatible with 3 V/5 V MCUs; drives internal gate driver directly |
| CS | Analog current sense output | Delivers proportional ISENSE = IOUT/K₁; supports OFF-state open-load and short-to-VCC diagnosis |
| SEn | Sense enable control | Active-high logic input; disables CS output during low-power sleep to reduce system leakage |
Key Features
| Feature | Design Value |
|---|---|
| Integrated CurrentSense analog feedback | Enables real-time load monitoring and closed-loop current control without external shunt resistors or op-amps |
| OFF-state open-load detection | Identifies disconnected loads before activation using CS pin voltage threshold (±12 V clamp), preventing false fault reporting |
| Self-limiting fast thermal transients | Dynamically throttles output current during rapid junction temperature rise, avoiding hard thermal shutdown in pulsed loads |
| Reverse battery protection | Operates safely with −13 V applied to VCC; no external diode required for 12 V system reverse-polarity immunity |
| ISO 7637-2 Pulse 5b compliance | Withstands 40 V clamped load-dump transients (RL = 4 Ω), meeting OEM requirements for engine bay electronics |

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 RON (6 mΩ typ.), no analog CS output-only digital fault flag; requires external sense resistor for current monitoring | Lacks continuous current feedback; suitable for on/off control only, not closed-loop thermal or motor control | Select when cost sensitivity outweighs diagnostic granularity and analog feedback is unnecessary |
| NXP UJA1075ATW/3V | System basis chip (SBC) with integrated CAN transceiver and LDO; high-side driver section rated for 3.5 A only | Not a drop-in replacement-designed for microcontroller power management, not high-power actuation | Choose only for mixed-signal gateway nodes where CAN + low-power HSD integration is prioritized over 135 A capability |
Compared with VN7004CH, BTS7004-1EPP trades analog sensing for lower unit cost and simpler layout, while UJA1075ATW/3V serves entirely different system roles-neither matches the VN7004CH's combination of 135 A current limit, 4 mΩ RON, and integrated CurrentSense for automotive actuators.

FAQ
What is the maximum continuous output current rating for VN7004CH?
The VN7004CH does not specify a fixed "continuous" current rating due to thermal dependence. Its DC current limit (ILIMH) is 135 A typ. at VCC = 13 V and Tj = 25 °C, but actual sustainable current depends on PCB copper area, ambient temperature, and airflow. With a 4-layer board and 2 cm² heatsink, it supports ≥35 A continuous at 85 °C ambient without derating.
How does the CurrentSense (CS) pin function during OFF-state open-load detection?
When INPUT = LOW and SEn = HIGH, the CS pin outputs a voltage proportional to load current. In OFF-state open-load, the CS voltage rises to ~−12 V (clamped), signaling disconnection. This occurs because no current flows through the internal sense FET, causing the CS node to float toward the negative clamp rail-detectable by an external comparator or ADC.
Can VN7004CH drive inductive loads without external flyback protection?
Yes-the device integrates active voltage clamping during turn-off, limiting VOUT to VCC − 41 V (typ.) for 2 A inductive current with 6 mH load. This eliminates need for external TVS or Zener diodes in most automotive solenoid and motor applications, provided PCB layout minimizes parasitic inductance in the power loop.
Is VN7004CH pin-compatible with earlier ST high-side drivers like VN7003AH?
No-VN7004CH uses the Octapak package with 6 terminals, while VN7003AH uses PowerSSO-36. Pin functions differ significantly: VN7004CH consolidates all OUTPUT pins into one terminal and adds dedicated SEn, whereas VN7003AH has separate OUT1/OUT2 and no SEn. Layout and schematic redesign are required for migration.
