TLE75008-EMD
Overview
In Limp Home mode (Fail-Safe mode) the input pins are directly routed to channels 2 and 3. When IDLE pin is
“low”, it is possible to activate the two channels using the input pins independently from the presence of the digital
supply voltage.
The device provides diagnosis of the load via Open Load at OFF state (with DIAG_OSM.OUTn bits) and short
circuit detection. For Open Load at OFF state detection, a internal current source I_OL can be activated via SPI.
Each output stage is protected against short circuit. In case of Overload, the affected channel switches OFF when
the Overload Detection Current I_L(OVLn) is reached and can be reactivated via SPI. In Limp Home mode operation,
the channels connected to an input pin set to “high” restart automatically after Output Restart time t_RETRY(LH) is
elapsed. Temperature sensors are available for each channel to protect the device against Over Temperature.
The power transistors are built by N-channel power MOSFET . The inputs are ground referenced TTL compatible.
The device is monolithically integrated in Smart Power Technology.
