... PWM. Channel 4-6 (also with integrated charge pump) can be configured to work as highside switch or lowside switch. This IC can be used to drive standard automotive loads in highside or lowside applications with switching frequencies kHz. In addition the TLE6288R can be used to drive autonomously inductive peak & ...

... GND Logic ground pin, the heat slug has to be connected to this potential. FSIN Disable pin. If the FSIN pin logic low state, it switches all outputs OFF. The pin has an internal pull-up structure. Reset Reset pin. When the reset is low all channels are off, the internal biasing is deactivated, all internal registers are cleared and the supply-current consumption is reduced (standby mode) ...

... Channel Overtemperature Flag: In case of overtemperature in any output channel in on state the overtemperature Flag in the SPI diagnosis register is set (change bit 3 from 0 to 1). This bit can be used to distinguish between Overload and Overtemperature (both HL combination) and is reset by switching OFF/ON the affected channel. In addition the DIAG6 / Overtemp pin is set low (if configured as Overtemp Flag). ...

... Open load and switch bypassed detection activated or deactivated (OL+SB): For each of the 3 configurable channels (Ch4 to Ch6) the open load and switch bypassed diagnosis can be deactivated. In lowside configuration the open load and the short to GND detection can be deactivated, in highside configuration the open load and short to battery detection. ...
