QUICK START GUIDE FOR DEMONSTRATION CIRCUIT 1904 UNIVERSAL DUAL-BATTERY CHARGER/SELECTOR LTC1960
●Demonstration circuit 1904 is a dual battery Power-Path™ and charger controller featuring the LTC1960. The input voltage is 15V to 20V. The charger output voltage is programmed via SPI serial interface. The maximum charge current is 4A. The demo board has been optimized to work with 3- and 4-cell Li-ion batteries. A jumper is provided to select the LowBatt voltage trip point. The board will not charge any battery without a device to program it. By default the board powers up in 3-Diode mode, which simply means all three power paths to the output (load) are on.
●PowerPath selection is programmed over the SPI interface.
●This is not a stand-alone demonstration circuit—an SPI interface and associated software is required for proper evaluation. Linear Technology offers demonstration circuit 1223A-B, which includes an SPI-to-USB-port adapter and software to control demonstration circuit 1904.
