7 A H-Bridge for DC-Motor Applications TLE7209-3R 1Overview 1.1 Features Operating supply voltage 5 V to 28 V Typical R = 150 m for each output transistor DSon (at 25 C) Continuous DC load current 5 A (T < 100 C) C Output current limitation at typ. 6.6 A 1.1 A Short circuit shut-down for output currents over 8 A Logic- inputs TTL/CMOS-compatible Output switching frequency up to 30 kHz Rise and fall times optimized for 0.5-2 kHz Over-temperature protection Short circuit protection Undervoltage disable function Diagnostic by SPI or Status-Flag (configurable) Enable and Disable inputs PG-DSO-20-65 power package Green Product (RoHS compliant) Functional Description The TLE7209-3R is an intelligent full H-Bridge, designed for the control of DC and stepper motors in safety critical applications and under extreme environmental conditions. The H-Bridge is protected against over-temperature and short circuits and has an under voltage lockout for all the supply voltages V (main DC power supply). All malfunctions S cause the output stages to go tristate. The device is configurable by the DMS pin. When grounded, the device gives diagnostic information via a simple error flag. When supplied with V = 5 V, the device works in CC SPI mode. In this mode, detailed failure diagnosis is available via the serial interface.
