Datasheet

1 General Description

The AS8650 is a companion IC which combines power management

functions and a fully conforming high speed CAN Transceiver in one

high performance analog device for automotive applications. The

AS8650 is powered by the battery, provides 4 output voltage levels

of which 3 outputs can be individually programmed in the range of

1.8V to 3.3V with a maximum current consumption up to 120mA at

the LDO voltage regulator outputs. An integrated DCDC converter

with a very high efficiency for the 5V output supplies the 3 voltage

regulators and ensures a voltage stability of ± 2.5%. The

combination of DCDC converter with low-drop-out voltage regulators

makes the AS8650 suitable for all Automotive Control Units where

power efficiency is a must.

The AS8650 provides a high-speed CAN interface up to 1Mbps

communication rate conforming to ISO 11898. The AS8650 provides

wake-up via remote wake-up at CAN bus lines and a local wake pin.

The watchdog unit provides three different timing functions: start-up,

window- and time-out watchdog; configurable via the SPI and I2C

interface.

Voltage monitoring is implemented for the battery supply, DCDC

output and the 3 LDO regulator outputs. Undervoltage will be

signalled on the INTN pin to the microcontroller. All diagnostics and

status flags can be accessed with the SPI interface.

The product is available in a 36-pin QFN (6x6x0.9) package.
