Voltage Regulator with integrated LIN Transceiver
Figure 19 - RIN characteristics of EN-input
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.

Figure 20 - EN controlled via MCU
If the application donât 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.
