STMicroelectronics EV-VN7007ALH

Overview

EV-VN7007ALH from STMicroelectronics is an evaluation board pre-assembled with the VN7007ALH single-channel smart high-side driver in Octapak package, operating from 4–28 V supply, delivering 7 mΩ on-resistance and 100 A current limiting, designed for automotive load switching and diagnostic prototyping.

For engineers reviewing the EV-VN7007ALH datasheet, EV-VN7007ALH pinout, EV-VN7007ALH application, or EV-VN7007ALH equivalent, this board enables rapid validation of VIPower® M0-7 high-side driver behavior-including proportional current sense (Multisense), OFF-state open-load detection, thermal shutdown indication, and configurable latch-off-without external component design.

Technical Context

The EV-VN7007ALH implements ST's VIPower® M0-7 technology to evaluate the VN7007ALH's real-time protection and diagnostics: it supports 3 V/5 V CMOS-compatible input control (IN0), fault reporting via FR_DIAG, and analog current sensing through Multisense output (J3 pin 8) scaled by external Rsense.

Board-level thermal design includes FR4 PCB with 2 copper layers, 35 µm thickness, thermal vias (0.5 mm Ø, 1.1 mm pitch), and junction-to-ambient thermal resistance of 39 °C/W-enabling stable operation under sustained 100 A transient loads within automotive ambient conditions.

FAQ

What is the purpose of the Multisense pin (J3 pin 8) on the EV-VN7007ALH board?

The Multisense pin delivers an analog current proportional to the load current, enabling real-time monitoring and closed-loop control. Its output requires an external sense resistor (mounted at TP1–TP2) to set scaling; typical configurations use 10–100 mΩ values to generate 1–10 mA output per 10 A load current, compatible with standard ADC inputs.

How does the FR_DIAG pin function during fault conditions?

FR_DIAG controls fault response mode: pulled low disables latch-off and enables auto-restart; pulled high configures latch-off on overtemperature or power limitation. It also enables OFF-state open-load detection when asserted, allowing diagnostics without load energization-critical for pre-ignition system checks in engine control units.

Can the EV-VN7007ALH board drive inductive loads like DC motors directly?

Yes-the board supports inductive loads up to 100 A peak with built-in protections: active current limiting, fast thermal transient suppression, and overvoltage clamping during switch-off. Users must ensure external flyback path (e.g., freewheeling diode) is implemented per VN7007ALH datasheet recommendations to manage back-EMF energy safely.

Is the EV-VN7007ALH compatible with 3.3 V microcontrollers?

Yes-IN0 (J3 pin 13) features hysteresis and is fully compatible with both 3.3 V and 5 V CMOS logic levels. Input threshold is 1.3 V (min) for high and 0.7 V (max) for low, ensuring noise-immune switching across automotive voltage tolerances without level-shifting circuitry.
