AS8506

Battery Cell Monitor and Balancer IC

The AS8506 is a battery management IC dedicated to support

cell voltage measurement, monitoring, cell balancing and

temperature measurement functions in Li-Ion battery stacks for

electric/hybrid electric vehicles or in other

General Description

industrial/consumer/PV battery applications.

There are two device versions available:

• The AS8506 is AEC - Q100 automotive qualified.

• The AS8506C is for industrial and other applications.

Ambient temperature range for both products is from -40°C to

+85°C.

It features cell voltage diagnosis with externally adjustable

upper and lower cell voltage limits, fast cell voltage capture on

request through 12-bit SAR ADC, passive cell balancing by

simultaneous comparison of actual cell voltages with a

reference cell voltage and temperature measurement on two

external NTC sensors through 12-bit ADC.

Cells that are above reference will sequentially be discharged

through integrated switches and one external resistor.

There is also an active balancing option through factory setting

to sequentially charge cells which are below reference from an

external DC-DC Flyback converter and an integrated low side

driver.

The device can be used flexibly for battery stacks up to 7 cells

with a minimum stack voltage of 6V and a maximum stack

voltage of 32V.

It can be chained to support battery packs of virtually any

number of cells in synchronized mode through chained clock

and trigger signal.

The status of the battery stack is communicated to outside

world through OR’d voltage_ok signal and balance ready signal.

For further understanding in regards to the contents of the

datasheet, please refer to the Reference Guide located at the end

of the document.
