H-Bridge Driver IC

Features

• Compatible to very low ohmic normal

level input N-Channel MOSFETs

• PWM – DIR - Interface

• PWM frequency up to 50kHz

• Operates down to 7.5V

supply voltage

• Low EMC sensitivity and emission

• Adjustable dead time with shoot through protection

• Deactivation of dead time and shoot through protection possible

• Short circuit protection for each Mosfet

• Driver undervoltage shut down

• Reverse polarity protection for the driver IC

• Fast disable function / Inhibit for low quiescent current

• Input with TTL characteristics

• 2 bit diagnosis

• Thermal overload warning for driver IC

• Shoot through protection

• Integrated bootstrap diodes

Application

• Dedicated for DC-brush high current motor bridges in PWM control mode for 12, 24 and 42V powernet applica-

tions.

• The input structure allows an easy control of a DC-brush motor
