Infineon NovalithIC™ high current motor drivers pair a p-channel high-side switch and a n-channel low-side switch to create a half-bridge, adding an integrated circuit to protect the device. The IC also features microprocessor-compatible logic level inputs, diagnosis with current sense, slew rate adjustment and dead-time generation. Overtemperature, overvoltage, undervoltage, overcurrent and short-circuit protection is part of the package. Two hallmark features set this multichip, half-bridge configuration apart - it generates neither charge pump emissions nor cross-current. The half-bridge combines with others to form H-bridge and three-phase drive configurations. Features Low path resistance down to 16mOhm and high-current capability up to 70A typ Low quiescent current of 7μA PWM capability up to 25kHz + active freewheeling Switched mode current limitation Logic level inputs Integrated over-/undervoltage, overtemperature and overcurrent protection Status flag diagnosis Analog current sense Adjustable slew rate Fast switching speed, rise and fall times of 500ns Applications Automotive Motors Automation and Control Cordless tools Robotics Home Appliances Block Diagram
