STMicroelectronics EV-VN9016AJ

Overview

EV-VN9016AJ from STMicroelectronics is a pre-assembled evaluation board for the VN9016AJ single-channel automotive high-side driver in PowerSSO-16 package, operating from 4–28 V with 16 mΩ on-state resistance and 50.6 A current limit. It enables rapid integration into 12 V grounded-load systems such as glow plugs, heating elements, and ADAS sensor supplies, featuring analog multiplexed diagnostics (current, voltage, temperature), fault reset, and protection against overtemperature, overload, short-to-VCC, and open-load.

For engineers reviewing the EV-VN9016AJ datasheet, EV-VN9016AJ pinout, EV-VN9016AJ application, or EV-VN9016AJ equivalent, this board provides validated reference design, plug-and-play load/microcontroller connectivity, and real-time diagnostic feedback via CS and FaultRST pins - critical for functional safety validation and ASIL-B–aligned power distribution prototyping.

Technical Context

The EV-VN9016AJ implements ST's VIPower M0-9 technology to support deep cold-cranking down to 4 V while delivering precise proportional current sensing via the CS pin, with ±5% accuracy across 0–50.6 A. Its integrated diagnostics include multiplexed analog outputs for load current, VBAT_ADC, and die temperature, all time-multiplexed onto a single pin.

Protection logic includes configurable latch-off on overtemperature or power limitation, triggered by dedicated FaultRST pin; undervoltage lockout below 4 V; overvoltage clamp at 36 V; and reverse-battery resilience via self-turn-on prevention. Standby current remains ≤0.5 µA for battery-sensitive applications.

FAQ

What is the primary function of the EV-VN9016AJ evaluation board?

The EV-VN9016AJ is a ready-to-use evaluation platform for the VN9016AJ high-side driver IC. It integrates all recommended external components per the datasheet, enabling immediate connection of microcontroller signals (IN, FaultRST, SEn), 12 V supply (VBAT), and load - eliminating custom PCB design for functional validation and diagnostic testing.

Does the board support real-time current sensing and fault reporting?

Yes. The board routes the VN9016AJ's multiplexed CS pin to CN8 pin 5, allowing oscilloscope or ADC monitoring of proportional load current (0–50.6 A range), VBAT_ADC, and internal die temperature in time-division sequence. Fault conditions including short-to-ground, short-to-VCC, and thermal shutdown are reported via CS waveform anomalies and latched status accessible through FaultRST control.

Can the EV-VN9016AJ be used with 3.3 V microcontrollers?

Yes. The VN9016AJ input stage is CMOS-compatible with both 3 V and 5 V logic levels. The board includes pull-up resistors (R1, R3) on IN and In_PullUP lines, and configurable SEn and FaultRST pins accept standard 3.3 V TTL/CMOS signals without level-shifting circuitry.

Is the board compliant with automotive qualification standards?

The underlying VN9016AJ IC meets AEC-Q100 Grade 0 (−40 °C to +150 °C), ISO 16750-2 (electrical loads), and LV124 Rev. 2013 (cold-cranking). While the EV-VN9016AJ board itself is not qualified, its layout and component selection follow ST's automotive reference design guidelines for EMC robustness and thermal performance in vehicle environments.
