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
