Analog Devices LTC4100EG | Demoboard DC512B

Description

Demonstration circuit DC512B is a single battery switching step-down charge controller featuring the LTC4100. The recommended input power is 15 to 20V at 3.5A. A two-position jumper allows choice of protected outputvoltage range suitable for 3- and 4-Cell Li-ion batteries. Removal of the jumper allows full output voltage range. The maximum charge current is 4A.

The demo board is initially configured for 12.6V at 3A for popular 3-cell Li-ion battery packs. LTC4100 will automatically charge a Smart Battery to termination as soon as input power is applied with a battery connectedprior to power up. A VOUT pin automatically provides power to the system load from the wall adapter or battery.Status LEDs are provided for CHG, ACP,SMBALERT and SMBus activity.

The optional DC1223A-B SMBUS to USB adapter and associated software to control, monitor, and data log the system for demonstration purposes only. This software is not required to charge a battery with the DC512B.Contact your LT representative for ordering a DC1223A-B.
