The TLE4208G is a protected quad Half-bridge Driver IC built using Infineon's bipolar high voltage power technology DOPL. In a cascade configuration up to three actuators (DC motors) can be connected between the four half-bridges. The four half-bridges are configured as 2 dual-half-bridges, which are supplied and controlled separately. Operation modes forward (CW), reverse (CCW), brake and high impedance are invoked from a standard interface. Furthermore the built-in features like diagnosis, over and under-voltage-lockout, short-circuit protection, over-temperature protection and the very low quiescent current in standby mode will open a wide range of applications.
- Very low current consumption in standby (Inhibit) mode
- Output protected against short circuit
- Error flag diagnosis
- Over-voltage lockout and diagnosis
- CMOS/TTL compatible inputs with hysteresis
- No crossover current
- Internal clamp diodes
- Over-temperature protection with hysteresis and diagnosis
