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.

Full digital control is provided by two serially-accessible

registers that allow programming of off-time, blank-time,

dead-time, mixed decay ratios, synchronous rectification,

master clock source selection, and division ratio and idle

mode. All internal timings are derived from a master clock

that can be generated on-chip or provided by an external

clock such as the system clock of the master controller. A

programmable divider allows for a wide range of external

system clock frequencies.

The internal fixed off-time PWM current-control timing is

programmed via the serial interface to operate in slow, fast,

and mixed current-decay modes. The desired load-current level

and direction is set via the serial port with a direction bit and

two 6-bit linear DACs in conjunction with a reference voltage.

The seven bits of control allow maximum flexibility in torque
