STMicroelectronics EV-VND5E050J

Overview

EV-VND5E050J from STMicroelectronics is a pre-assembled evaluation board for the VND5E050J-E double-channel high-side VIPower® driver in PowerSSO-12 package, designed for automotive grounded-load control with 4.5–28 V operation, 50 mΩ R_ON, 27 A current limit, and dual analog current-sense diagnostics. It enables rapid prototyping of smart power switching in body electronics modules.

For engineers reviewing the EV-VND5E050J datasheet, EV-VND5E050J pinout, EV-VND5E050J application, or EV-VND5E050J equivalent, this board provides verified thermal layout (31 °C/W R_thj-amb), dual-output connectivity via J1/J2 headers, STAT_DIS-controlled diagnostic disable, and CMOS-compatible 3/5 V input interface - all critical for validating high-side driver integration in automotive ECUs.

Technical Context

This evaluation board implements a fixed-layout, two-layer FR4 PCB (38 × 38 mm, 70 µm Cu, 1.6 mm thickness) with thermal vias (0.3 mm diameter, 1.2 mm spacing) to support junction-to-ambient thermal resistance of 31 °C/W for the mounted VND5E050J-E IC. It routes all device pins-including INPUT1/2, OUTPUT1/2, STATUS1/2, STAT_DIS, and VCC/GND-to accessible 0.1" pitch headers.

The board integrates no active components beyond the VND5E050J-E; external load resistors, reverse-battery protection diodes, and optional RC snubbers (per AN4210) must be added per application. Diagnostic feedback is configurable via STAT_DIS pin pull-up to enable wired-OR status sharing across multiple drivers.

FAQ

What is the purpose of the STAT_DIS pin on the EV-VND5E050J board?

The STAT_DIS pin allows global disabling of diagnostic feedback from the VND5E050J-E IC. When pulled high, it deactivates both STATUS1 and STATUS2 outputs, enabling wired-OR connection with other compatible drivers without signal contention. This function is implemented directly on the board via a header-accessible net and requires no soldering.

Does the EV-VND5E050J board include protection components like reverse-battery diodes or snubbers?

No. The board contains only the VND5E050J-E IC and passive routing. External reverse-battery protection diodes, RC snubbers, and load resistors must be added per AN4210 guidelines. ST explicitly states these are required for safe operation and are omitted to maintain flexibility across load types and voltage classes.

Can the EV-VND5E050J be used with 3.3 V microcontrollers?

Yes. The VND5E050J-E features CMOS-compatible inputs that accept logic-high thresholds down to 2.0 V, making it fully interoperable with 3.3 V and 5 V microcontrollers. Input pins (INPUT1/INPUT2) are directly routed to J1 headers with no level-shifting circuitry required.

What thermal performance can be expected when operating at full 27 A current limit?

At 27 A peak, junction temperature rise is ~837 °C above ambient (27² × 0.05 Ω × 31 °C/W), exceeding safe limits. The board supports sustained 5 A continuous output with <10 °C rise. For higher currents, external heatsinking or forced airflow per UM1556 is mandatory - the board's thermal design targets functional validation, not full-power stress testing.
