STMicroelectronics EV-VN7010AJ

Overview

EV-VN7010AJ from STMicroelectronics is an evaluation board pre-assembled with the VN7010AJ single-channel smart high-side driver in PowerSSO-16 package, operating from 4–28 V supply with 10 mΩ on-state resistance, 91 A current limit, and MultiSense analog feedback for load current, VCC, and chip temperature. It enables rapid prototyping of automotive high-side switching applications including resistive, inductive, and capacitive loads.

For engineers reviewing the EV-VN7010AJ datasheet, EV-VN7010AJ pinout, EV-VN7010AJ application, or EV-VN7010AJ equivalent, this board provides validated thermal layout (R_thj-amb = 39 °C/W), CMOS-compatible 3 V/5 V control interface, fault reset (FaultRST), sense enable (S_EN), and multiplexed diagnostic output (MultiSense) - all critical for automotive power management validation.

Technical Context

The EV-VN7010AJ implements ST's VIPower® M0-7 technology to evaluate the VN7010AJ's real-time protection and diagnostics: undervoltage shutdown, overvoltage clamp, configurable latch-off on overtemperature/power limitation, and loss-of-ground/VCC detection. Its PCB integrates thermal vias (0.5 mm diameter, 1.1 mm spacing) and 2-layer 35 µm Cu FR4 construction for junction-to-ambient thermal resistance of 39 °C/W.

Board-level connectivity supports full functional verification: J3 connector provides dedicated pins for IN (CMOS-compatible input), FaultRST (active-low fault reset), S_EN (sense enable), SEL0/SEL1 (multiplexer address), and MultiSense (current-mode analog output). External RSENSE mounting options (through-hole TP1–TP2 or SMD pads) allow user-defined current sensing gain.

FAQ

What is the purpose of the MultiSense pin on the EV-VN7010AJ board?

The MultiSense pin delivers a proportional current output that multiplexes three diagnostics: load current (via internal current mirror), VCC supply voltage, and chip junction temperature. Selection is controlled by SEL0/SEL1 logic inputs. This eliminates need for separate ADC channels and enables single-pin analog monitoring of critical system parameters.

How does the FaultRST pin function during overtemperature events?

FaultRST is an active-low input that unlatches the VN7010AJ output after thermal shutdown or power-limiting faults. When held low, it forces auto-restart mode; when pulsed low then released, it resets latched faults. This allows flexible fault recovery strategies - either manual reset or continuous retry - without cycling power.

Can the EV-VN7010AJ be used with 3.3 V microcontrollers?

Yes - all digital control pins (IN, FaultRST, S_EN, SEL0, SEL1) are fully compatible with both 3.3 V and 5 V CMOS logic levels. Input hysteresis on the IN pin ensures noise immunity, and the VN7010AJ's internal level-shifting circuitry guarantees reliable switching across the specified voltage range.

What thermal performance can be expected without additional heatsinking?

With its optimized 2-layer FR4 PCB (35 µm Cu, thermal vias at 1.1 mm pitch), the EV-VN7010AJ achieves 39 °C/W junction-to-ambient thermal resistance. At 91 A current limit and 10 mΩ R_ON, this supports ~83 W dissipation before reaching 150 °C junction temperature - sufficient for short-duration peak loads in automotive testing.
