5 kW low voltage high current inverter for automotive motor control applications
Introduction
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 includes a board 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 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.

UM2673 STEVAL-CTM004V1 power board STEVAL-CTM004V1 power board The STEVAL-CTM004V1 power board of the evaluation kit has 36 STH31*N10F7 N-channel Power MOSFETS in the H²PAK-6 package. A gate resistor is placed near each power MOSFET to eliminate parasitic oscillation. A pull-down resistor between the gate and the source of each transistor helps to avoid capacitive coupling driving the transistor and unwanted switch-on when gate is floating. -
