STMicroelectronics EV-VN9006AJ

Overview

EV-VN9006AJ from STMicroelectronics is a pre-assembled evaluation board for the VN9006AJ single-channel smart high-side driver in PowerSSO-16 package, designed for 12 V automotive grounded loads with 3 V/5 V CMOS interface. It supports deep cold cranking (LV124 Rev. 2013), delivers 82 A current limit, 6 mΩ on-state resistance, and multiplexed analog diagnostics including load current sense, temperature feedback, and fault detection.

For engineers reviewing the EV-VN9006AJ datasheet, EV-VN9006AJ pinout, EV-VN9006AJ application, or EV-VN9006AJ equivalent, this board enables rapid validation of VN9006AJ's high-side drive performance, diagnostic accuracy, thermal management under overload, and fault reset behavior in real automotive power distribution systems.

Technical Context

The EV-VN9006AJ implements ST's VIPower M0-9 technology to integrate protection and diagnostics into a single high-side switch. It provides configurable latch-off on overtemperature or power limitation via dedicated FaultRST pin, and supports OFF-state open-load detection using external pull-up.

Its Multisense analog output pin multiplexes three signals-load current (proportional mirror), supply voltage (VBAT_ADC), and die temperature-enabling system-level monitoring without additional ADC channels. All protections-including undervoltage shutdown, overvoltage clamp, reverse battery tolerance, and ESD-are hardware-asserted and independent of microcontroller control.

FAQ

What is the purpose of the FaultRST pin on the EV-VN9006AJ board?

The FaultRST pin unlatches the VN9006AJ output after a fault event such as overtemperature or power limitation, restoring normal operation when pulled high. It can also disable latch-off functionality entirely if held low, enabling retry-based fault recovery strategies in safety-critical automotive subsystems.

How does the Multisense analog output function on this evaluation board?

The Multisense pin (CN8 pin 5) delivers time-multiplexed analog signals: load current (1:1000 proportional mirror), VBAT supply voltage (via R65/R64 divider), and chip temperature (internal PTAT). Timing and decoding are controlled by SEn and IN signals per DB4941 timing diagram, requiring MCU GPIO and ADC coordination.

Can the EV-VN9006AJ board drive inductive loads like solenoids or relays?

Yes - the VN9006AJ on this board is qualified for automotive inductive loads per ISO 7637-2/3 and AEC-Q100. Its integrated clamp diode, fast thermal transient self-limiting, and short-to-VCC detection ensure safe switching of solenoids, fuel injectors, and HVAC actuators without external flyback components.

Is external sense resistor required for current measurement on this board?

No - the VN9006AJ uses an internal high-precision current mirror (not external Rsense) for analog current feedback. The board includes optional test points (TP1/TP2) and footprint for external Rsense only for calibration reference or alternative sensing topologies, not for basic operation.
