TH8061

LIN Bus Transceiver with integrated Voltage Regulator

RESET Output

The RESET output is switched from low to high if VSUP is

switched on and VCC>VRES after the time tRES.

If the voltage VCC drop below VRES then the RESET output is

switched from high to low after the time trr has been reached.

The voltage level for the RESET output is 4,65V and the

corresponding reset time tRES is 100ms.

Wake up with BUS traffic

If the regulator is put in standby mode it can be wake up

with the BUS interface. Every pulse on the BUS (high

pulse or low pulse) with a pulse width of min. 45µs will

switch on the regulator.

After the BUS has wake up the regulator, it can only be

switched off with a high level followed by a low level on

the EN pin.

Temperature Limitation

If the Junction temperature 150ºC < Tj < 170ºC the over

temperture recognition will be active and the regulator

voltage will be switched off. After Tj fall below 140ºC the

TH8061 will be initialized, not depending on of the volt-

age levels on EN and BUS.

The function of the TH8061 is possible between TAmax

and the switch off temperature, but small parameter dif-

ferences can appear.
