Preliminary Data Sheet AS8530 LIN Tr a ns ce i ve r w it h I nt eg ra t e d Volt a ge Re gul at or a nd MCU Interface for Automotive Applications www.DataSheet4U.com 1 General Description The AS8530 is a general purpose companion IC for sensor and actuator LIN slaves offering LIN transceiver and low drop voltage regulator. As well it provides a 2-wire microcontroller interface through shared EN and TX pins to access a window watchdog with RC oscillator, control registers, backup registers and monitoring information. The IC is fabricated in a high voltage CMOS technology which is able to withstand voltages up to 50V. The product is available in SOIC package with exposed pad. Under voltage reset with factory options LIN bus transceiver with load independent slew control conforming to LIN 2.1 and SAE J2602, short circuit protection, TX time out fail safe feature, over temperature warning and shut down 6kV ESD on LIN pin according to IEC 61000-4-2 Window watchdog if factory enabled. Micro controller 2-wire interface through shared pins for watchdog trigger, monitoring, register read /write Chip ID for traceability and module ID 8 Backup registers to store data during VCC shut down 8 pin epSOIC package -40ºC to +125ºC ambient operating temperature 2 Key Features Operating voltage 6 to 18V, max 42V for 500ms Linear, low-drop voltage regulator: VCC = 5V±3% or 3.3V as a factory programming option 50mA load current Operating modes: Normal and Standby or Normal and Sleep as a facto...
