STMicroelectronics EV-VND5T100AJ

Overview

EV-VND5T100AJ from STMicroelectronics is an evaluation board pre-assembled with the VND5T100AJ-E dual-channel high-side power switch, designed for automotive-grade resistive and inductive load control. It operates from 8–36 V supply, features 35 mΩ on-state resistance, 42 A current limitation, and integrated proportional current sense with two analog outputs (MultiSense 1 & 2). The board enables rapid prototyping of smart power switching in body electronics modules.

For engineers reviewing the EV-VND5T100AJ datasheet, EV-VND5T100AJ pinout, EV-VND5T100AJ application, or EV-VND5T100AJ equivalent, this evaluation board supports direct microcontroller interface via CMOS-compatible inputs, fault reset via FR_STBY, and configurable current sensing using through-hole or SMD sense resistors - all without external component design.

Technical Context

The board implements ST's VIPower® M0-7 technology, integrating two independent high-side drivers with latch-off protection against overload, short-to-VCC, and thermal shutdown. Each channel includes hysteresis on IN0/IN1 inputs and delivers proportional current sense output scaled by external Rsense.

Fault reporting is centralized through dual MultiSense pins (J3.8 and J3.18), supporting simultaneous monitoring of both channels. Reset requires a low pulse on FR_STBY (J3.7), while sustained low on all inputs + FR_STBY forces standby mode with ≤2 µA supply current.

FAQ

What is the purpose of the FR_STBY pin on the EV-VND5T100AJ board?

The FR_STBY pin (J3.7) serves dual functions: a low pulse resets latch-off conditions (e.g., after thermal shutdown or overload), while holding it low-along with all inputs-forces the device into ultra-low-power standby mode (<2 µA). This enables fail-safe recovery and energy-efficient system sleep states in automotive ECUs.

How do I configure current sensing on the EV-VND5T100AJ?

Current sensing uses external sense resistors connected across TP1–TP2 (through-hole) or dedicated SMD pads. MultiSense 1 (J3.8) and MultiSense 2 (J3.18) deliver analog current proportional to OUT0 and OUT1 load currents. Scaling is determined by Rsense value and internal 1:2000 current mirror ratio - no calibration required for basic diagnostics.

Does the EV-VND5T100AJ support 5 V microcontroller logic levels?

Yes. Both IN0 (J3.13) and IN1 (J3.14) accept 3.0 V CMOS-compatible inputs with built-in hysteresis, making them fully interoperable with standard 3.3 V and 5 V microcontrollers without level-shifting circuitry. Input thresholds are defined per VND5T100AJ-E datasheet: VIH ≈ 2.0 V, VIL ≈ 0.8 V.

Can the board drive inductive loads like solenoids or relays?

Yes. The VND5T100AJ-E integrates active VCC clamp and robust protection against inductive kickback, including loss-of-ground and loss-of-VCC detection. Its 58 V max transient supply rating and self-limiting thermal response make it suitable for automotive solenoids, fuel injectors, and HVAC actuators without external flyback diodes.
