Charger IC Targets Back-up Power Applications
Suitable for battery management in applications such as server, memory backup and medical equipment, Linear Technologies LTC4110 offers four operating modes: battery backup, battery charge, “no-loss” battery calibration and shutdown. The device can provide a supply voltage to a system load from a main supply or battery and can also charge a battery, and is capable of supplying voltages above or below the input supply rail, allowing optimization of the battery configuration independent of input supply considerations. In a failure situation, the device uses the battery as a power source through low-loss switches to continue providing a supply voltage. The low-loss battery calibration mode discharges the battery into the system load and shutdown mode disconnects the battery from the load.
