TLE7209-2R

7 A H-Bridge for DC-Motor Applications TLE 7209-2R Preliminary Datasheet 1 1.1 Overview Features Operating supply voltage 5 V to 28 V Typical RDSon = 150 mΩ for each output transistor (at 25 °C) Continuous DC load current 3.5 A (TC < 100 °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 input P-DSO-20-12 power package Type TLE 7209-2R Functional Description The TLE 7209-2R 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 “VS” (main DC power supply). All malfunctions 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 VCC = 5 V, the device works in SPI mode. In this mode, detailed failure diagnosis is available via the serial interface.
