Overview
The BTN8982TA, produced by Infineon Technologies, is an integrated high current half-bridge IC designed for motor drive applications. It is part of the NovalithIC™ family, which 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 IC is optimized for protected high current PWM motor drives, offering a cost-effective solution with very low board space consumption. It features logic level inputs, diagnosis with current sense, slew rate adjustment, dead time generation, and comprehensive protection against overtemperature, undervoltage, overcurrent, and short circuit conditions.
