DIO5907x

Standalone 1-Cell 1.1 A Linear Battery Charger

with Power Path

Descriptions

Features

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 (V_IN-DPM) prevents the charger

from crashing incorrectly configured USB

sources.



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

(V_IN- DPM) for protection against poor USB

sources



10% charge current accuracy

0.7% 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

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. 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.



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

Applications



Smart phones

Portable media players

Portable navigation devices

Low-power handheld device
