STMicroelectronics EV-VNH7100BAS

Overview

EV-VNH7100BAS from STMicroelectronics is a preassembled evaluation board for the VNH7100BAS VIPower® M0-7 full-bridge motor driver IC, designed to simplify prototyping of automotive-grade H-bridge motor control circuits. It integrates the VNH7100BAS in SO-16N package with recommended passive components (33 nF/220 µF capacitors, 1 kΩ–10 kΩ resistors), supports 4–28 V operation, 15 A current limiting, and 20 kHz PWM speed control.

For engineers reviewing the EV-VNH7100BAS datasheet, EV-VNH7100BAS pinout, EV-VNH7100BAS application, or EV-VNH7100BAS equivalent, this board enables rapid validation of bidirectional DC motor control, current sensing via MultiSense output, thermal performance under load, and microcontroller interface compatibility using INA/INB/SEL0/PWM/GND signals.

Technical Context

The EV-VNH7100BAS implements a complete hardware reference design for the VNH7100BAS dual high-side + dual low-side H-bridge, featuring electrically isolated leadframes and symmetrical SO-16N mechanical layout to support manufacturable PCB assembly. It delivers direct connectivity for motor (OUTA/OUTB), power supply (VCC/GND), and MCU control (INA/INB/PWM/SEL0/CS) without external component design.

Thermal management is enabled by FR4 double-layer PCB (47 × 41 mm, 35 µm Cu, 1.6 mm thickness) with 0.5 mm thermal vias spaced at 1.1 mm, achieving junction-to-ambient thermal resistance of 55 °C/W (HSD MAX) - critical for sustained 15 A peak current operation in automotive ambient conditions.

FAQ

Does EV-VNH7100BAS include the VNH7100BAS IC?

Yes, the board is preassembled with the VNH7100BAS full-bridge motor driver IC in SO-16N package. No soldering or component placement is required - users can immediately connect power, motor, and microcontroller signals per J1/J2 pinout definitions.

What is the purpose of the SEL0 pin on EV-VNH7100BAS?

SEL0 selects which internal diagnostic or current-sense information from the VNH7100BAS MultiSense pin is routed to the microcontroller. It enables multiplexed readout of motor current, temperature, or fault status without additional pins, supporting compact MCU interface designs.

Can EV-VNH7100BAS drive brushed DC motors above 24 V?

No - the board is designed for the VNH7100BAS's specified 4–28 V operating range. While the IC supports up to 41 V transient supply voltage, sustained operation beyond 28 V risks exceeding safe operating area limits and invalidates thermal derating assumptions used in the board's 55 °C/W R_thj-amb rating.

Is heatsinking required when using EV-VNH7100BAS at 15 A?

Yes - the board's integrated thermal vias and copper pour provide baseline heat dissipation, but at 15 A continuous load, forced air cooling or external heatsink attachment to the SO-16N exposed pad is recommended to maintain junction temperature within 150 °C limit, especially above ambient 50 °C.
