STMicroelectronics EV-VN7E010AJ

Overview

EV-VN7E010AJ from STMicroelectronics is an evaluation board for the VN7E010AJ single-channel smart high-side driver in PowerSSO-16 package, designed to drive 12 V automotive grounded loads with 3 V/5 V CMOS-compatible control, featuring analog current sense, thermal shutdown with configurable latch-off, and protection against undervoltage (2.85 V min cranking), overvoltage, short-to-VCC, and open-load faults.

For engineers reviewing the EV-VN7E010AJ datasheet, EV-VN7E010AJ pinout, EV-VN7E010AJ application, or EV-VN7E010AJ equivalent, this board enables rapid prototyping of protected high-side switching for ADAS sensors, headlamps, and resistive/inductive automotive loads - with pre-assembled VN7E010AJ, on-board thermal vias, sense resistor mounting options (through-hole or SMD), and dedicated diagnostic pins (CurrentSense, S_EN, SEL0/SEL1, FaultRST).

Technical Context

The EV-VN7E010AJ implements ST's VIPower M0-7 technology to support deep cold-cranking operation down to 2.85 V while delivering 88 A peak current limit and 10.5 mΩ typical on-state resistance. Its diagnostic architecture integrates a multiplexed analog CurrentSense output that reports load current, supply voltage, and die temperature via SEL0/SEL1 address lines.

Thermal performance is enabled by a 2-layer FR4 PCB (25 mm × 41.5 mm, 35 µm Cu, 1.6 mm thickness) with 0.5 mm diameter thermal vias spaced at 1.1 mm intervals, achieving ≤39 °C/W junction-to-ambient thermal resistance - critical for sustained high-current automotive switching without external heatsinking.

FAQ

What is the purpose of the SEL0 and SEL1 pins on the EV-VN7E010AJ board?

SEL0 and SEL1 are address inputs to the VN7E010AJ's multiplexed CurrentSense analog output. They select between three diagnostic modes: load current sensing (default), supply voltage feedback, or internal chip temperature reporting - enabling full system-level health monitoring using a single analog ADC input on the host controller.

Does the EV-VN7E010AJ include the VN7E010AJ IC pre-mounted?

Yes, the board ships fully assembled with the VN7E010AJ high-side driver IC soldered in its PowerSSO-16 package. No additional assembly is required to begin functional evaluation - only connection of power, load, and microcontroller control signals via J3 header is needed.

Can the EV-VN7E010AJ be used for continuous 10 A load switching?

Yes - with proper PCB layout and ambient conditions, the board sustains ≥10 A continuous current. Its thermal design (39 °C/W R_thj-amb, thermal vias, exposed pad) ensures junction temperature remains within safe limits under sustained load, as verified per ST's DB4002 data brief and thermal characterization.

How is open-load detection implemented during OFF-state?

OFF-state open-load detection uses the IN_PullUP pin (J3 pin 5) to enable an internal pull-up on the IN input. When the load is disconnected and IN is pulled low, the resulting voltage shift at IN triggers diagnostic reporting via the CurrentSense output - provided S_EN is asserted and SEL0/SEL1 are configured for current-sense mode.
