Product details
Overview
VN7010AJTR from STMicroelectronics is a single-channel automotive smart high-side driver in PowerSSO-16 package, featuring MultiSense analog feedback for load current (±5% accuracy), VCC supply voltage, and chip temperature sensing. It delivers 10 mΩ on-state resistance, 91 A typical current limit, and operates across 4–28 V supply with <0.5 µA standby current-designed for headlamp control in 12 V grounded-load systems.
For engineers reviewing the VN7010AJTR datasheet, VN7010AJTR pinout, VN7010AJTR application, or VN7010AJTR equivalent, key selection criteria include its configurable latch-off fault recovery via FaultRST, reverse-battery protection support with external components, CMOS-compatible 3 V/5 V input interface, and multiplexed diagnostic output enabling system-level health monitoring without additional ADC channels.
Technical Context
The VN7010AJTR integrates VIPower® M0-7 technology to combine power switching, real-time diagnostics, and robust protection in one monolithic device. Its MultiSense pin multiplexes three analog signals-load current (via proportional current mirror), VCC, and TCHIP-using SEL0/SEL1 address lines, with dedicated SEn enable control for low-power mode coordination.
Protection architecture includes active power limitation during overload, thermal shutdown with configurable latch-off, undervoltage lockout (4 V trip, 5 V reset), overvoltage clamp (41–52 V), and detection of OFF-state open-load, short-to-VCC, and loss of ground/VCC. Fault recovery is managed through active-low FaultRST, supporting both auto-restart and latched fault states.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 4–28 V operating; supports full automotive battery range including cold-crank (4 V) and load-dump (up to 40 V transient) |
| RON | 10 mΩ typ. at 5 A / 25°C; enables low conduction loss and minimal self-heating in high-current headlamp loads |
| ILIMH | 91 A typ. current limit; sustains brief inrush currents while preventing MOSFET destruction during short-circuit events |
| ISTBY | ≤0.5 µA max. at 25°C; ensures negligible battery drain during vehicle sleep mode |
| MultiSense Accuracy | ±5% load current sense error; provides reliable closed-loop feedback for ECU-based current regulation and fault classification |

| ESD Rating | 4 kV HBM on INPUT/MultiSense/FaultRST pins; meets automotive EMC robustness requirements without external protection |
Pinout & Package
Package: PowerSSO-16 (exposed thermal pad, surface-mount, RoHS-compliant). Pins 9–12 and 13–16 are internally bonded-output terminals must be paralleled externally on PCB for current sharing and thermal spreading.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Battery supply input | Primary power rail connection; clamped to 40 V transient; feeds internal regulator and gate driver |
| OUTPUT | High-side switched output | Single-channel power output; pins 1–8 and 13–16 collectively form one high-current path to load |
| GND | Ground reference | Reverse-battery protected return path; requires external diode/resistor network per datasheet Fig. 4.1 |
| INPUT | CMOS-compatible control input | Hysteresis-enabled logic input; accepts 3 V or 5 V MCU I/O; drives internal gate driver directly |
| MultiSense | Multiplexed analog diagnostic output | Current-source output delivering proportional ILOAD, VCC, or TCHIP; requires external 10 kΩ pull-up resistor |
| SEn | Sense enable control | Active-high signal disabling MultiSense output during standby to reduce system leakage current |
| SEL0, SEL1 | Multiplexer address inputs | Select diagnostic channel: 00 = ILOAD, 01 = VCC, 10 = TCHIP, 11 = reserved |
| FaultRST | Fault reset/latch control | Active-low pin; unlatches output after overtemperature or power-limit fault; held low for auto-restart behavior |
Key Features
| Feature | Design Value |
|---|---|
| MultiSense analog feedback | Single-pin multiplexed reporting of load current (±5% accuracy), supply voltage, and die temperature-eliminates need for discrete sense resistors and external ADCs |
| Configurable fault latch-off | FaultRST pin allows system-level choice between latched shutdown (safe default) or auto-restart (for non-critical loads), reducing ECU intervention overhead |
| Ultra-low standby current | ≤0.5 µA at 25°C enables compliance with ISO 16750-2 sleep-mode current budgets for body control modules |
| Reverse battery protection ready | Supports external GND-line diode/resistor network (Fig. 4.1) to withstand −14 V reverse polarity without damage |
| Integrated overvoltage clamp | Clamps transients up to 40 V (ISO 7637-2 Pulse 5a) at VCC pin-reduces need for external TVS diodes in cost-sensitive designs |
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 BTS7012-1EPP | Higher RON (15 mΩ), no analog MultiSense; uses digital SPI for diagnostics | Lacks analog current/voltage/temperature multiplexing; requires SPI interface and external ADC for analog-equivalent data | Preferred when system already uses SPI bus and needs lower BOM count for digital diagnostics |
| NXP MC33883 | Lower current limit (60 A), standalone analog current sense only (no VCC/TCHIP feedback) | Provides only load current feedback; no integrated VCC or temperature monitoring capability | Selected where cost sensitivity outweighs multi-parameter diagnostic needs and thermal margin is sufficient |
Compared with VN7010AJTR, BTS7012-1EPP trades analog simplicity for digital configurability and MC33883 reduces integration depth to cut cost-making VN7010AJTR optimal for new headlamp platforms demanding comprehensive analog health monitoring with minimal MCU resource usage.

FAQ
What is the maximum continuous output current rating for VN7010AJTR?
The VN7010AJTR does not specify a fixed continuous current rating due to thermal dependence. Its 91 A current limit is a peak short-circuit threshold; sustained current depends on PCB copper area, ambient temperature, and airflow. With 200 cm² of 2 oz copper on a 4-layer board, it supports ~12 A continuous at 85°C ambient per JEDEC JESD 51-7 thermal data.
How does the MultiSense pin distinguish between load current, VCC, and chip temperature readings?
The MultiSense pin outputs a proportional current corresponding to one parameter at a time, selected by SEL0 and SEL1 logic levels: 00 = load current, 01 = VCC, 10 = chip temperature. The external 10 kΩ pull-up resistor converts this current to a voltage readable by an MCU ADC. Timing diagrams in Figures 7 and 8 define minimum sampling windows for each mode.
Can VN7010AJTR drive inductive loads like fuel pumps without external flyback protection?
No external flyback diode is required for standard 12 V inductive loads because the device integrates active demagnetization energy handling (168 mJ max at VCC = 16 V). However, for high-inductance loads exceeding this limit-or where fast turn-off is critical-a Schottky diode across the load remains recommended to prevent voltage overshoot beyond the 40 V clamp.
Is the FaultRST pin mandatory for normal operation?
FaultRST is not mandatory for basic switching but is essential for fault recovery. If left unconnected or pulled high, the device enters permanent latch-off after any overtemperature or power-limit event and requires power cycle to reset. For production systems, connecting FaultRST to an MCU GPIO enables controlled fault clearing and diagnostic logging.
