- Analog/digital input/output interface
The evaluation system consists of the STEVAL-TTM001V1 inverter kit and the STEVAL-TTM002V1 control board running dedicated SPC5 Studio firmware.
The STEVAL-TTM001V1 evaluation kit is designed to demonstrate the highly efficient ST automotive-grade 100 V STripFET F7 series Power MOSFETs operating in typical low speed automotive low voltage ( battery up to 48 V), high current motor control applications. The kit consists of a driver board with a programmable L9907 FET driver with fault management to manage 36 STH315N10F7 Power MOSFETs on a separate isolated metal substrate (IMS) for improved heat dissipation.
A bus link capacitor board is included to condition the input supply from the 48V battery source, and a further current sensing board allows motor phase current information to be fed back to the MCU running the FOC control algorithms.
The control board interfaces with the inverter evaluation kit driver board and features the SPC560P50L3 automotive MCU with dedicated peripherals for motor control interfaces.
