Description

The L297 Stepper Motor Controller IC generates four phase drive signals for two phase bipolar and four

phase unipolar step motors in microcomputer-controlled applications. The motor can be driven in half step,

normal and wawe drive modes and on-chip PWM chopper circuits permit switchmode control of the current in

the windings. Afeature of this device is that it requires only clock, direction and mode input signals. Since the

phase are generated internally the burden on the microprocessor,and theprogrammer,is greatlyreduced.

Mounted in DIP20 and SO20 packages, the L297 can be used with monolithic bridge drives such as the

L298N , or with discrete transistors and darlingtons.
