STMicroelectronics EV-VND7030AJ

Overview

EV-VND7030AJ from STMicroelectronics is an evaluation board pre-assembled with the VND7030AJ dual-channel smart high-side driver in PowerSSO-16 package, operating from 4–28 V supply, delivering 31 mΩ on-state resistance per channel and supporting 56 A current limitation. It enables rapid prototyping of automotive load control with integrated MultiSense analog diagnostics and thermal protection.

For engineers reviewing the EV-VND7030AJ datasheet, EV-VND7030AJ pinout, EV-VND7030AJ application, or EV-VND7030AJ equivalent, this board provides verified electrical connectivity, thermal management, and diagnostic signal routing for VND7030AJ-based designs targeting automotive resistive/inductive/capacitive loads.

Technical Context

The EV-VND7030AJ implements a complete reference design for the VND7030AJ VIPower M0-7 device, integrating recommended external components including input pull-ups, sense resistor pads (TP1–TP2), and decoupling capacitors (C1–C4). It supports all diagnostic modes via SEL0/SEL1 multiplexing and fault reset via active-low FaultRST.

Board-level thermal performance is validated with R_thj-amb = 39 °C/W under specified FR4 PCB conditions (2-layer, 35 µm Cu, 1.6 mm thickness, thermal vias at 1.1 mm pitch). J3 connector provides direct access to all critical signals: IN0/IN1, MultiSense, S_EN, FaultRST, and +5V supply.

FAQ

What is the purpose of the MultiSense pin on the EV-VND7030AJ board?

The MultiSense pin (J3 pin 8) delivers a multiplexed analog current output proportional to load current, VCC supply voltage, or chip temperature-selected via SEL0/SEL1. It enables single-wire diagnostics without additional ADC channels, supporting real-time health monitoring of the driven load and driver IC.

Does the EV-VND7030AJ board include the VND7030AJ IC pre-soldered?

Yes, the board ships fully assembled with the VND7030AJ dual high-side driver in PowerSSO-16 package mounted and tested. All recommended passive components-including decoupling capacitors (C1–C4), input pull-ups (R1–R7), and sense resistor pads (TP1–TP2)-are populated per ST's datasheet guidelines.

How is open-load detection implemented on this evaluation board?

Open-load detection in OFF-state is enabled via the S_EN pin (J3 pin 9) and optional external pull-up resistor on J3 pin 5 (IN_PullUP). When S_EN is high and the output is off, the board monitors voltage at the output node to detect open circuits-supporting fail-safe diagnostics without added external circuitry.

Can the EV-VND7030AJ be used with 3.3 V microcontrollers?

Yes, both IN0 and IN1 inputs are compatible with 3 V and 5 V CMOS logic levels, featuring built-in hysteresis. The FaultRST and S_EN pins also accept 3.3 V logic, and the +5V supply rail (J3 pin 6) can be powered from an external 3.3 V source if system-level voltage translation is required.
