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 7.5 V

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 can be disabled and adjusted

• 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

• Green Product (RoHS compliant)

• AEC Qualified

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

General Description

H-bridge driver IC for MOSFET power stages with multiple protection functions. The TLE6184G is very similar to

the TLE6281G. The major difference is that the Short Circuit protection level of the TLE6284G can be adjusted

by external resistors or even disabled. The pin outs are different as well.
