ATAVRSB200

ATAVRSB200 is a development platform for SB20x smart battery reference designs, which offers an easy way to start evaluation and hence development of smart battery applications using AVR microcontrollers. The SB200 is not in itself a reference design, but is intended to be used with e.g. SB201-1, which is a reference design that demonstrates implementation of a single cell smart battery (Li ion). 16340/CR123A battery cells can be inserted in the SB200 battery sockets, and a SB20x is inserted in the dedicated daughter board socket. This forms a “battery pack” with a given number of cells, safety protection and full battery capacity monitoring capabilities. Alternately other cell types can be soldered into the SB200. To simulate the use of the “battery pack” the SB200 features a Charger that can charge the battery pack, and a Constant Current Load that can simulate an application that draws power from the battery pack.

• Auto limitation of charging voltage and current
• Auto termination of charging when charging period expires
• Adjustable constant current Load for battery discharging
• Adjustable constant current Load for battery discharging
• Battery charger: charges up to 19V & 2A, auto-limitation of charging, auto-termination of charging

Warnings

Be aware that the heat sinks of the Constant Current Load can get very hot. The shunt resistors (0.5ohm) at the load and from the charger will also get very hot. Do not touch them.

Notes

The SB200 will limit the temperature to approximately 125°C by turning off the load if the temperature rises above this point.
