STMicroelectronics EV-VN7004CLH

Overview

EV-VN7004CLH from STMicroelectronics is a pre-assembled evaluation board for the VN7004CLH single-channel smart high-side driver in Octapak package, designed for 12 V automotive grounded loads with 3 V/5 V CMOS-compatible control, 4 mΩ R_ON, 135 A current limit, and integrated analog current sense (Multisense), thermal shutdown, open-load detection, and short-to-V_CC protection - used in glow plug control and relay replacement.

For engineers reviewing the EV-VN7004CLH datasheet, EV-VN7004CLH pinout, EV-VN7004CLH application, or EV-VN7004CLH equivalent, this board enables rapid validation of VIPower® M0-7 high-side switching behavior, diagnostic feedback accuracy, thermal performance under pulsed load conditions, and latch-off configuration via FR_DIAG pin in automotive power distribution systems.

Technical Context

The EV-VN7004CLH implements ST's VIPower® M0-7 technology to deliver robust high-side switching with real-time analog current sensing (Multisense pin) and configurable fault latching. It supports 4–28 V operating supply range and withstands up to 40 V transient voltage, enabling use in harsh 12 V automotive environments.

Board-level design integrates recommended external components per VN7004CLH datasheet, including provision for through-hole or SMD sense resistor placement (TP1–TP2), dedicated IN0 control input with hysteresis, and FR_DIAG pin for enabling OFF-state diagnostics and selecting auto-restart vs. latch-off on overtemperature or overload.

FAQ

Is EV-VN7004CLH a standalone IC or an evaluation board?

EV-VN7004CLH is a fully assembled evaluation board - not an IC. It hosts the VN7004CLH single-channel smart high-side driver in Octapak package, with supporting circuitry including IN0 control input, Multisense analog current output, FR_DIAG fault configuration pin, and provision for external sense resistor mounting at TP1–TP2.

What load types can be validated using this board?

This board validates 12 V automotive grounded loads including glow plugs, PTC heaters, DC motors, and high-power resistive/inductive actuators. Its 135 A current limit, 4 mΩ R_ON, and thermal shutdown ensure safe operation during inrush and stall conditions typical of these loads.

How is current sensing implemented on EV-VN7004CLH?

Current sensing uses the Multisense pin (J3 Pin 8), delivering an analog current proportional to load current. A user-mounted sense resistor (through-hole or SMD at TP1–TP2) sets scaling; no external op-amp is required, enabling direct ADC interfacing for real-time load monitoring.

Can FR_DIAG be used to disable latch-off during testing?

Yes - pulling FR_DIAG low disables latch-off and enables auto-restart after fault clearance; pulling it high activates latch-off on overtemperature or overload. This pin also enables OFF-state open-load detection, allowing diagnostics without activating the output.
