●Description:
●The TLE 7209-2R is a 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.
●Summary of Features:
● Operating supply voltage 5 V to 28 V
● Typical RDSon = 150 mΩ for each output transistor (at 25 °C)
● Continuous DC load current 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 inputs
● PG-DSO-20-37, -65 power package
● Green Product (RoHS compliant)
●Benefits:
● Full protection and diagnosis capability enables for use in safety relevant applications covers full automotive temperature range
● No external freewheeling diodes required SPI interface enables direct communictation with microcontroller
