A3985SLDTR-T Product details

Description

The A3985 is a flexible dual full-bridge gate driver suitable for driving a wide range of higher power industrial bipolar 2-phase stepper motors or 2-phase brushless dc motors. It can also be used to drive two individual torque motors or solenoid actuators. Motor power is provided by external N-channel power MOSFETs at supply voltages from 12 to 50 V.



Features and Benefits

▪ Serial interface for full digital control

▪ Dual full-bridge gate drive for N-channel MOSFETs

▪ Dual 6-bit DAC current reference

▪ Operation over 12 to 50 V supply voltage range

▪ Synchronous rectification

▪ Cross-conduction protection

▪ Adjustable mixed decay

▪ Fixed off-time PWM current control

▪ Low-current idle mode
