5 kW low voltage high current inverter for automotive motor control applications

STEVAL-TTM001V1

Overview

The STEVAL-TTM001V1 evaluation kit is designed to demonstrate the highly efficient ST automotive-grade 100 V STripFET F7 series Power MOSFETs and BLDC motor driver IC operating in typical automotive low voltage (car battery up to 48 V), high current motor control applications.

The kit has two boards to sense and condition currents and a driver board with a programmable L9907 FET driver with full diagnostics to manage all 36 STH315N10F7 Power MOSFETs on a separate power board also included in the kit.
The driver board also includes an ST motor control connector to interface with any compatible ST motor control board (not included in the kit), and various other connectors and jumpers for monitoring and protection, motor position feedback information, and auxiliary power.
