Description
The TLE8278GV50 is an electronic component model that falls under the product category of IC Chips. It is a SPI programmable H-bridge designed specifically for the control of DC motors in safety-critical automotive applications. This component features four selectable current ranges, two selectable slew rate settings, and extensive diagnosis capabilities via SPI interface. The TLE8278GV50 also monitors the digital supply voltage VDD and shuts down the output stages in case of over- or undervoltage, providing a safe switch-off path in case of malfunction of the digital control circuitry. It is designed to reduce power dissipation in extreme thermal conditions by linearly reducing the current limitation threshold for junction temperatures over 165°C. Additionally, it has the ability to operate the two half bridges independently to drive two separate loads like solenoids or unidirectional DC motors.
