Revision 0.01

1 - 29

Preliminary Data Sheet

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.

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

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

3 Applications

The AS8530 is a System Basis Chip for automotive LIN networked

sensor or actuator slaves.
