TH8061

Voltage Regulator with integrated LIN Transceiver

The wide input voltage range allows different EN control possibilities. If the EN input is connected to an

CMOS output of the MCU, a falling edge switches the TH8061 into sleep mode (the regulator is also

switched off). The wake up is only possible via the bus line.

If the application don’t needs the wake up capability of the TH8061 a direct connection EN to VSUP is

possible. In this case the TH8061 operates in permanent normal mode. Also possible is the external (outside

of the module) control of the EN line via a VBAT signal.
