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.
