STMicroelectronics EV-VNHD7008AY

Overview

EV-VNHD7008AY from STMicroelectronics is a preassembled evaluation board for the VNHD7008AY VIPower® full-bridge motor driver IC, designed to simplify prototyping of automotive H-bridge motor control systems. It integrates the PowerSSO-36 packaged IC with recommended passive components, supports 4–28 V operation, delivers up to 51 A current limit per channel, and enables PWM speed control up to 20 kHz with MultiSense current/voltage/temperature monitoring.

For engineers reviewing the EV-VNHD7008AY datasheet, EV-VNHD7008AY pinout, EV-VNHD7008AY application, or EV-VNHD7008AY equivalent, this board provides immediate electrical connectivity, thermal heat-sinking, and direct microcontroller interface via INA/INB, PWM, SEL0/SEL1, and SENSE_EN signals - eliminating external component design effort for rapid validation of VNHD7008AY-based motor drive circuits.

Technical Context

The EV-VNHD7008AY implements a complete hardware reference for ST's VNHD7008AY dual high-side + external low-side MOSFET H-bridge driver. It routes all critical signals-including GATE_LSA/GATE_LSB, OUTA/OUTB, MULTI-SENSE, and SENSE_EN-to accessible connectors (J1–J5) and test points (TP1–TP4), while embedding layout-optimized power paths and thermal vias per FR4 4-layer PCB spec (45 × 65 mm, 35 µm Cu, 1.6 mm thickness).

Board-level design adheres strictly to VNHD7008AY datasheet recommendations: includes 470 µF/50 V bulk capacitance (C8), 100 nF decoupling (C1, C9, C11), 10 nF gate-drive filtering (C4–C5, C10), and precision sense-resistor network (R5–R10) for MultiSense analog output scaling, enabling accurate real-time monitoring of motor current, battery voltage, and die temperature.

FAQ

Does EV-VNHD7008AY include the VNHD7008AY IC?

Yes. The board is preassembled with the VNHD7008AY VIPower® full-bridge driver in PowerSSO-36 package, including all required external passives (capacitors, resistors, inductors) as specified in the device datasheet for functional operation.

What microcontroller interfaces are supported?

The board exposes direct TTL-compatible signals: INA/INB (direction control), PWM (speed modulation), SEL0/SEL1 (MultiSense mode selection), SENSE_EN (analog monitor enable), and MULTI-SENSE (combined analog output) - all routed to standard 0.1" pitch headers (J1–J5).

Can EV-VNHD7008AY drive brushed DC motors directly?

Yes. With external N-channel MOSFETs installed in low-side configuration (Q1, M1 positions on board), it forms a complete H-bridge capable of bidirectional control and braking of brushed DC motors up to 51 A peak, under 4–28 V supply.

Is thermal management integrated?

Yes. The board uses a 4-layer FR4 PCB with thermal vias (0.5 mm Ø, 1.1 mm pitch) beneath the VNHD7008AY exposed pad, achieving R_thj-amb = 28 °C/W (HSD MAX), enabling sustained operation at rated current without additional heatsink in most lab environments.
