DESCRIPTION
FEATURES
● Wide supply voltage sphere (10 to 35 V)● Bipolar, constant current PWM function. (Topside transistors PWM function, maximum current is 0.8 Amps.)
● Few external components. (This IC can be operated with 1 capacitor and 2 resistances.)
● 4 phases input style (include the protection function of output through current).
● Output current charge function (2 bits, 4 type currents).
● Thermal protection circuit.
● Include flywheel diodes. Application
● Printer, PPC and Facsimile. It can control the direction of motor current and output motor current (4 steps) by I0, I1 terminals. Also, it can drive the two-phase bipolar stepper motor by one IC as it includes two current control circuits.
