DS1259-Battery management chip
Features Facilitate uninterruptible power supply only when main VCC is unavailable Use battery low forward voltage drop Power fail signal interrupt processor, or write protected memory Power consumption is less than 100 nA Battery current low battery warning signal Battery can be disconnected after command When VCC is applied, the battery will automatically reconnect with the DS1212 non-volatile controller x 16 chips directly with backup 16 RAM
Optional 16-pin SOIC surface mount package
The DS1259 battery management chip is a low-cost battery management system for portable and non-volatile electronic devices. The battery input pin is connected to a battery powered CMOS electronics when mains power is lost through the VCCO pin through an efficient switching circuit. When supplying power from the battery, the power failure signal is active to alert the electronic reset circuit of the power status. Energy losses during transport and handling are avoidable reset pulses that lead to battery isolation from other elements in the circuit.
