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.
