Datasheet  
AS8530  
LIN Transceiver with Integrated Voltage Regulator and  
MCU Interface for Automotive Applications  
Typically 45µA quiescent current in standby mode,  
Typically 35µA quiescent current in sleep mode  
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.  
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  
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.  
Window watchdog if factory enabled  
Micro controller 2-wire interface through shared pins for  
watchdog trigger, monitoring, register read /write  
The IC is fabricated in a high voltage CMOS technology which is  
able to withstand voltages up to 42V.  
Chip ID for traceability and module ID  
8 Backup registers to store data during VCC shut down  
ep-SOIC8 package  
The product is available in ep-SOIC8 package.  
-40ºC to +125ºC ambient operating temperature  
2 Key Features  
Operating voltage 6V to 18V  
3 Applications  
The AS8530 is a System Basis Chip for automotive LIN networked  
sensor or actuator slaves.  
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
