Overview
The MOTIX™ BTN8962TA, produced by Infineon Technologies, is an integrated high current half bridge designed for motor drive applications. It is part of the NovalithIC™ family and includes one p-channel highside MOSFET and one n-channel lowside MOSFET, along with an integrated driver IC in a single package. This configuration eliminates the need for a charge pump, thereby minimizing electromagnetic interference (EMI). The integrated driver IC features logic level inputs, diagnosis with current sense, slew rate adjustment, dead time generation, and protection against overtemperature, undervoltage, overcurrent, and short circuit. This device provides a cost-optimized solution for protected high current PWM motor drives with minimal board space consumption.
