Jiangsu DIO5907x• Rev. 1.6 - 1 - DIO5907x Standalone 1-Cell 1.1 A Linear Battery Charger with Power Path Features Fully compliant USB charger Selectable 100 mA and 500 mA maximum input current 100 mA maximum current limit ensures compliance to USB-IF standard Input-based dynamic power management (VIN- DPM) for protection against poor USB sources 10% charge current accuracy 1% charge voltage accuracy 28 V input rating with overvoltage protection Integrated dynamic power path management (DPPM) function simultaneously and independently powers the system and charges the battery Supports up to 1.1 A charge current with current monitoring output (ISET) Programmable input current limit up to 1.1 A for wall adapters Programmable termination current (DIO59078) Programmable pre-charge and fast-charge safety timers Reverse current, short-circuit and thermal protection NTC thermistor input Proprietary start-up sequence limits inrush current Status indication–charging/done, power good Descriptions The DIO5907x series of devices are integrated Li-Ion linear chargers and system power path management devices targeted at space-limited portable applications. The devices operate from either a USB port or an AC adapter and support charge currents up to 1.1 A. The input voltage range with input overvoltage protection supports unregulated adapters. The USB input current limit accuracy and start up sequence allow the DIO5907x to meet USB-IF inrush current specifications. Additionally, the input dynamic power management (VIN-DPM) prevents the charger from crashing incorrectly configured USB sources. The DIO5907x 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 while monitoring the charge current separately. Applications Smart phones Portable media players Portable navigation devices Low-power handheld device |
