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

Application In industrial and automotive electronics, power full-bridge DC motor drivers are mostly used for bidirectional motor drives. The two TTL and CMOS-compatible control inputs act on the output as follows: Status 1 2 3 4 Input 1 L L H H Input 2 L H L H Output 1 Output 2
VQL VQL VQH VQH
VQL VQH VQL VQH
VQL means: Lower power unit conducting; upper power unit blocked. VQH means: Upper power unit conducting; lower power unit blocked.
The following examples illustrate the operation: Status 1: Motor is slowed down Status 2: Motor turns right Status 3: Motor turns left Status 4: Motor is slowed down

Circuit Description Input Circuit The control inputs consist of TTL and CMOS-compatible Schmitt triggers with hysteresis. Buffer amplifiers, controlled from these stages, convert the logic signal into the form required for driving the power output stages. Output Stages The output stages consist of two push-pull C stages. Using protective circuits for limiting the power dissipation makes the outputs short-circuit proof to ground and to supply voltage throughout the entire operating range. Positive and negative voltage peaks, which occur when switching inductive loads, are limited by integrated power diodes. Monitoring and Protecting Functions The IC is protected against thermal overloads by a temperature protecting circuit. In addition an internal circuit ensures that all output transistors are blocked for supply voltages below operating range. A monitoring stage logic for each output stage transistor detects whether the relevant transistor is active and in this case for sink operation (source operation) prevents the corresponding source transistor (sink transistor) from being turned on. Direct cross-over currents are effectively prevented with this method.
