P-TO220-7-2 Type TLE 4203 TLE 4203 S Description The integrated circuit TLE 4203 is a versatile double power driver of up to 4 A output current which is particularly suitable as a driver for DC motors in reversible operation. The push-pull power output stages operate in the switching mode and can be combined to a full-bridge configuration. The drive of the input stage is implemented using digital logic. The device contains a temperature protection logic, output stages protected against short-circuit and integrated free-wheeling diodes. Typical applications are for follow-up control, servo drives, servo motors, drive mechanisms, etc. Ordering Code Q67000-A8121 Q67000-A9101 Package P-TO220-7-1 P-TO220-7-2
