STMicroelectronics EV-VND5E050K

Overview

EV-VND5E050K from STMicroelectronics is a pre-assembled evaluation board for the VND5E050K-E dual-channel high-side VIPower® driver in PowerSSO-24 package, supporting automotive grounded-load switching with 50 mΩ R_ON, 27 A current limit, and integrated diagnostics including short-to-ground/VCC detection, open-load sensing, and overtemperature auto-restart.

For engineers reviewing the EV-VND5E050K datasheet, EV-VND5E050K pinout, EV-VND5E050K application, or EV-VND5E050K equivalent, this board enables rapid prototyping of 4.5–28 V automotive load control systems with thermal vias, dual-input CMOS-compatible interface, and STAT_DIS-configurable diagnostic feedback.

Technical Context

The EV-VND5E050K implements a dedicated hardware interface for the VND5E050K-E, featuring two independent high-side output channels with dedicated STATUS pins and shared STAT_DIS control. It provides PCB-level thermal management via 2-layer FR4 construction (38 × 43 mm), 70 µm copper, 0.3 mm thermal vias on 1.2 mm pitch, achieving 29.5 °C/W junction-to-ambient thermal resistance.

Board connectivity uses two 12-pin headers (J1/J2) mapping all device pins-including INPUT1/2, OUTPUT1/2, STATUS1/2, STAT_DIS, VCC, and GND-with redundant OUTPUT pins (3× per channel) to support high-current routing and low-impedance return paths.

FAQ

Is the EV-VND5E050K board pre-assembled with the VND5E050K-E IC?

Yes. The board ships fully assembled with the VND5E050K-E double-channel high-side driver soldered in its PowerSSO-24 package. No additional assembly is required to begin functional evaluation of input control, output switching, and diagnostic status reporting.

What external components are needed to operate the EV-VND5E050K?

The board requires an external 4.5–28 V DC supply connected to J1 pins 1 (VCC) and 2 (GND), plus logic-level input signals (3.3 V or 5 V CMOS) on J1 pins 5 (INPUT1) and 10 (INPUT2). Load connections must be made to J2 OUTPUT1/OUTPUT2 pins; no additional passive components are mandatory for basic operation.

Does the EV-VND5E050K support wired-OR diagnostics with other similar boards?

Yes. Pulling the STAT_DIS pin (J1 pin 4) high disables all diagnostic outputs, enabling wired-OR connection of multiple STATUS pins from identical or compatible evaluation boards without contention, as specified in the VND5E050K-E datasheet.

Can the EV-VND5E050K be used for thermal validation of the VND5E050K-E in my design?

Yes. The board's documented thermal performance (R_th(j-amb) = 29.5 °C/W) was measured under defined conditions: 2-layer FR4, 70 µm Cu, thermal vias, and forced convection. It serves as a validated reference for estimating junction temperature rise in early-stage thermal modeling.
