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 applications.
• The input structure allows an easy control of a DC-brush motor General Description
