STMicroelectronics EV-VN5E050J

Overview

EV-VN5E050J from STMicroelectronics is a pre-assembled evaluation board for the VN5E050J-E single-channel VIPower® high-side driver in PowerSSO-12 package, rated for 4.5–28 V operation, 50 mΩ R_ON, and 27 A current limitation. It enables rapid prototyping of automotive grounded-load control with integrated diagnostics, thermal management, and 3 V/5 V CMOS-compatible interface.

For engineers reviewing the EV-VN5E050J datasheet, EV-VN5E050J pinout, EV-VN5E050J application, or EV-VN5E050J equivalent, this board delivers verified thermal vias (0.3 mm diameter, 1.2 mm spacing), dual-output routing (J2 pins 8–11), STAT_DIS-controlled diagnostic disable, and FR4 PCB layout optimized for VIPower M0-5 device validation in 12 V/24 V systems.

Technical Context

The EV-VN5E050J implements a dedicated hardware interface for the VN5E050J-E high-side driver, featuring four thermal vias per output pad and copper pour on both layers to achieve 31 °C/W junction-to-ambient thermal resistance. Its J1/J2 dual-header layout separates power input (VCC/GND), logic interface (INPUT/STAT_DIS/STATUS), and high-current output paths (four parallel OUTPUT pins).

Board-level design follows UM1556 VIPower Hardware Design Guide requirements: 70 µm Cu thickness, 1.6 mm FR4 substrate, and optional external resistors for STATUS pull-up and load isolation. No onboard passive components are included-external capacitors, flyback diodes, and load connections must be added per AN4210 guidelines.

FAQ

Does the EV-VN5E050J include the VN5E050J-E IC?

Yes, the board ships fully assembled with one VN5E050J-E high-side driver pre-soldered in PowerSSO-12 package. No rework or IC installation is required before initial power-up testing. The device is factory-tested and ready for functional validation with external load and microcontroller interface.

What external components are mandatory for operation?

A minimum external configuration requires a flyback diode across the load, input decoupling capacitor (≥10 µF ceramic + ≥100 µF electrolytic), STATUS pull-up resistor (10 kΩ to VCC), and load connection to J2 OUTPUT pins. These are specified in AN4210 and UM1556 to ensure safe switching and diagnostic accuracy.

Can STAT_DIS be used to disable diagnostics during multi-board wired-OR operation?

Yes - pulling STAT_DIS high disables all diagnostic feedback (including overload, short-circuit, and open-load signals), enabling wired-OR connection of multiple EV-VN5E050J boards to a shared STATUS line. This allows centralized fault monitoring without signal contention.

Is thermal performance validated for continuous 27 A operation?

No - the board achieves 31 °C/W R_th(j-amb) under defined test conditions (JEDEC High-K board), but continuous 27 A operation requires forced airflow or external heatsinking. The board supports pulsed or intermittent loads per VN5E050J-E datasheet SOA curves, not sustained maximum current.
