Control Logic
| |
\- Ensures safe power−up sequence and the correct reaction to different supply conditions
\- Controls mode transitions including the power management and bus wakeup treatment
\- Generates reset
3.3 V or 5 V VOUT Supply depending on the Version from a Low−drop Voltage Regulator
| |
\- Can deliver up to 70 mA with accuracy of ±2%
\- Supplies typically the ECU’s microcontroller
\- Undervoltage detector with a reset output to the supplied microcontroller
LIN Transceiver
| |
\- LIN2.x and J2602 compliant
\- TxD dominant timeout protection
\- Transceiver mode controlled by dedicated input pin
Protection and Monitoring Functions
| |
\- Thermal shutdown protection
\- Load dump protection (45 V)
\- LIN Bus pin protected against transients in an automotive environment
\- ESD protection level for LIN and VS > ±8 kV
These are Pb−Free Devices
