LIN SBC with Voltage Regulator and Watchdog
ADVANCE PRODUCT INFORMATION JUL 26, 2011
6.2
The on chip low drop voltage regulator provides the voltage V
version) at pin VDD. It supplies the peripheral circuitry of the SBC and the host MCU chip with typical
60mA (2%) or up to 100mA with lower accuracy.
The voltage regulator is activated in all operating modes except in sleep mode. In sleep mode the
voltage regulator is switched off.
The voltage regulator output current is limited to I

6.3.1
The LIN BUS Interface is conform to LIN Physical Layer Specification Revision 2.1 and can be used for
master or slave applications. The device has an internal slave termination implemented. Master
termination has to be applied externally.
