TLE7209-3R 7A H-Bridge for DC-Motor Applications Infineon Technologies TLE7209-3R 7A H-Bridge for DC-Motor Applications is designed to control DC and stepper motors in safety-critical applications and in extreme environmental conditions. The TLE7209-3R H-Bridge is protected against over-temperature and short circuits. The H-Bridge 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.
