The TLE6209R is an integrated Power H-Bridge with D-MOS output stages for driving bidirectional loads such as DC-motors. The design is based on Smart Power Technology? (SPT) which allows bi-polar, CMOS and power D-MOS devices on the same monolithic circuit. Operation modes forward (cw), reverse (ccw) and brake are invoked by two control pins PWM and DIR. Protection and a reliable diagnosis of over-current, open load, short-circuit to ground, to the supply voltage or across the load are integrated. Detailed diagnostic information is given via the 8-bit SPI status word. An integrated chopper current limitation limits the current to reduce power dissipation during mechanical block of a DC motor. Several device parameters can be set by the SPI control word. A 3-level temperature monitoring with pre-warning, warning and shutdown is included for controlled operation under critical power loss conditions.
- Outputs fully short-circuit protected
- Over and under-voltage-lockout
- Open load detection
- Detailed load failure diagnosis by SPI
- Minimized power dissipation due to active free-wheeling
- Low EMI due to voltage slope regulation
