General Description
The RELIN TH8060 consist a low drop voltage regulator 5V/100mA and a LIN Bus transceiver. The LIN-
transceiver is suitable for LIN-Bus systems conform to "LIN-Protocol Specification" Rev.1.3.
The combination of voltage regulator and bus transceiver in combination with the monitoring functions make
it possible to develop simple, but powerful and cheap slave nodes in LIN Bus systems.
The wide output current area and the configurable reset time and reset voltage works together with many
different microcontrollers.

Electrical Specification
All voltages are referenced to ground (GND). Positive currents flow into the IC.
The absolute maximum ratings (in accordance with IEC 134) given in the table below are limiting values that
do not lead to a permanent damage of the device but exceeding any of these limits may do so. Long term
exposure to limiting values may affect the reliability of the device. Correct operating of the device can't be
guaranteed if any of these limits are exceeded.
