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
