DIO5060B

The DIO5060B series are integrated Li-Ion linear chargers and system power path management devices that are targeted at space-limited portable applications. The charger accepts an input voltage of up to 25 V but is disabled when the input voltage exceeds the OVP threshold, typically 6.5 V, to prevent excessive power dissipation. The 25 V rating eliminates the overvoltage protection circuit required in a low input-voltage charger. The input voltage range with input overvoltage protection supports unregulated adapters. The DIO5060B features dynamic power path management (DPPM) that powers the system while simultaneously and independently charging the battery. The DPPM circuit reduces the charge current when the input current limit causes the system output to fall to the DPPM threshold; thus, supplying the system load at all times when monitoring the charge current separately. This feature reduces the number of charge and discharge cycles on the battery, allows for proper charge termination, and enables the system to run with a defective or absent battery pack.
