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.
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 watch-
dog 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 factory option
Typically 40µA quiescent current in standby mode, Typically
30µA quiescent current in sleep mode
