Analog Devices Inc. DC1104B Demo for LTC4009-2 Battery Chargers

Analog Devices DC1104B Demonstration Board is designed to help the user evaluate the performance of the LTC4009-2 Multi-Chemistry Battery Charger. The demonstration board features the LTC4009-2 Battery Charger and a demonstration circuit. The demonstration circuit is a single-battery, standalone charge controller with built-in charge termination.

The DC1104B Demonstration Board has a default battery charge voltage of 12.6V, and can automatically charge a battery as soon as an input power supply is applied from a connected battery. The DC1104B Demonstration Board operates with a 13.5V to 20V input voltage and maximum charge current of 2A. The charger output voltage is programmed by jumpers to support 1-, 2-, 3- and 4-cell Li-Ion batteries with a cell voltage of 4.2V/cell. Status LEDs for CHG, ACP, C/10, and ICL are integrated into DC1104B Demonstration Board for performance monitoring of the LTC4009-2. With a simple IC swap out, the DC1104B Demonstration Board can also support the LTC4009 and LTC4009-1.

Although this product is not a smart battery charger, designers can use the DC1104B Demonstration Board with the provided smart battery connector and the DC410 demo software for data logging. An optional DC410 SMBus-to-Serial port adapter and associated software allow the DC1104B Demonstration Board to monitor a smart battery for demonstration purposes.
