2 The SB100 Hardware
2.1 Connecting the SB100
2
AVR454
The SB100 consists of two main areas; the circuitry required for the smart battery
implementation and a simulator circuit for demonstrating the ATmega406 smart
battery designs capabilities. Figure 2-1 shows the areas on the SB100 board.
Figure 2-1. SB100 with smart battery and simulator circuits highlighted
In addition to the circuits that demonstrate the smart Battery features, a number of
connectors are available for in-system programming, on-chip debugging, SMBus
communication, connection of battery cells and more.
The hardware schematic, assembly drawings and Bill of Materials are found last in
this document. A Table of Contents is found on page 19.
The ATmega406 comes preprogrammed with the evaluation software described in
the AVR453 Application Note. It is however recommended to download the latest
revision of the firmware from the Atmel website.
To use the SB100 it needs to be connected to an SMBus host/charger, a battery pack
(or a simulated battery pack) and a number of jumpers need to be configured
correctly. Further, for programming and debugging it is required to hook up an Atmel
JTAGICE mkII. Note that ATmega406 does not support in-system serial
programming. Figure 2-2 shows the SB100 board with all connectors highlighted. The
various connectors and jumper blocks and are described in detail in the following
sections.
WARNING:
Li-Ion batteries must be handled with care as they may pose a safety hazard if
treated incorrectly. It is important that the development of smart Battery
applications are done by people that are skilled and knowledgeable of correct
use and handling of Li-Ion batteries.
A – Individual cell voltage simulation
B – Total cell stack voltage simulation
C – smart battery implementation
D – Charge/discharge current simulation
