PWM STEPPING MOTOR DRIVER
The TA7289P, TA7289F/FG are PWM solenoid driver designed
especially for use high efficiency stepping motor control.
It consist of 1.5A peak current drive capable output full bridge
driver, oscillation circuit for PWM switching, 4bit DA for output
current control and TTL compatible input circuit.
FEATURES
z Wide Range of Operating Voltage
: VCC (opr.) Min. = 6~27 V
z High Current Capability: IO Max = 1.5 A (PEAK)
z LSTTL Compatible Control Inputs (IN A, IN B)
z Few External Components Required.
z Buildin 4bit DAC.
TA7289F/FG
The TA7289FG is a Pb-free product.
The TA7289P is Sn plated product including Pb.
The following conditions apply to solderability:
*Solderability
