4-A DC Motor Driver TLE 4203 Overview Features - - - - - Integrated free-wheeling diodes Outputs short-circuit proof to VS and ground Thermal overload protection Blocking of the output stages upon undervoltage Final push-pull stage free of cross-over Bipolar IC P-TO220-7-1 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 bined 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 Semiconductor Group 1998-02-01 TLE 4203 . 3 4 5 VS1 GND VS2 Q2 IST2 IST1 Q1 AEP00618 Figure 1 Pin Configuration (top view) Pin Definition and Functions Pin No. 1 2 3 Symbol IST1 Function Control input for channel 1 (TTL/CMOS-patible), of non-inverting effect on the channel output.
