1 Introduction
ADLINK’s BattMan (Battery Management) module is a Smart Battery Management System
that supports two Smart Batteries and provides ATX power for a mobile embedded system.
The BattMan Smart Battery Reference System is a proof-of-concept battery power
subsystem that allows for quick development and integration of battery power into a COM
Express system in the following ways:
f To emulate the battery power subsystem functionality of your prototype system during
the design phase
f As a ready-made battery power subsystem for your customized system
f As a reference design to integrate a battery power subsystem into your custom-designed
carrier (schematic provided)
The BattMan Smart Battery Reference System is compliant with the Smart Battery Manager
Specification and uses the System Management Bus (SMBus) for communications between
the battery power subsystem, Smart Batteries and host system (COM module and carrier).
The BattMan module is ACPI compliant and provides complete battery management under a
supporting operating system. ADLINK's COM Express modules feature a BIOS that fully
supports all Smart Battery communications using existing interfaces defined in the COM
Express specification and are fully compatible with the BattMan module.
The BattMan module delivers power output to a standard ATX 20-pin connector and provides
an Auxiliary Power 4-pin Molex connector for storage devices. Power input is from a 19V AC/
DC adapter. When not connected to a host system, the BattMan module can function as a
stand-alone battery charger.
