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 “V_S” (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 V_CC = 5 V, the device works in
SPI mode. In this mode, detailed failure diagnosis is available via the serial interface.
