Description
The BTN7971B is a integrated high current half bridge for motor drive applications. It is part of the NovalithIC™
family containing one p-channel highside MOSFET and one n-channel lowside MOSFET with an integrated driver
IC in one package. Due to the p-channel highside switch the need for a charge pump is eliminated thus minimizing
EMI. Interfacing to a microcontroller is made easy by the integrated driver IC which features logic level inputs,
diagnosis with current sense, slew rate adjustment, dead time generation and protection against overtemperature,
overvoltage, undervoltage, overcurrent and short circuit.
The BTN7971B provides a cost optimized solution for protected high current PWM motor drives with very low
board space consumption.
