AS8530

AS8530 LIN Transceiver with Integrated Voltage Regulator and MCU Interface for Automotive Applications 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. It also 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 42V. The product is available in ep-SOIC8 package. Typically 45µA quiescent current in standby mode, Typically 35µA quiescent current in sleep mode Under voltage reset with factory options  LIN bus transceiver l conforming to LIN 2.1, TX time out fail safe feature, over temperature warning and shut down 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 2 Key Features ep-SOIC8 package -40ºC to +125ºC ambient operating temperature Operating voltage 6V to 18V Linear, low-drop voltage regulator: VCC = 5V ±5% or 3.3V ±5% as a factory programming option 50mA load current Operating modes: Normal and Standby or Normal and Sleep as a factory option 3 Applications The AS8530 is a System Basis Chip for automotive LIN networked s...
