Description

The BTM7745G is a fully integrated high current H-bridge for motor drive applications. It contains two p-channel

highside MOSFETs and two n-channel lowside MOSFETs with an integrated driver IC in one package. Due to the

p-channel highside switches 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,dead time

generation and protection against overtemperature, overvoltage, undervoltage, overcurrent and short circuit.

The BTM7745G provides an optimized solution for protected high current motor drives with very low board space

consumption.
