MP2696B
I2C-Controlled, Single-Cell Switching Charger
with Power-Path Management,
Boost Output, and 3.5A Input Current Limit
DESCRIPTION
FEATURES
The MP2696B is a highly integrated, flexible,
switch-mode, battery-charging, power-path
management device designed for a single-cell
Li-ion and Li-polymer battery. This device can
be used in a wide range of portable applications.
4.0V to 11V Operating Voltage Range
Up to 16V Sustainable Input Voltage
500mA to 3.6A Configurable Charge
Current
3.6V to 4.45V Configurable Charge
Regulation Voltage with ±0.5% Accuracy
500mA to 3.5A Configurable Input Current
Limit with ±10% Accuracy
Minimum Input Voltage Loop for Maximum
Adapter Power Tracking
Ultra-Low 25μA Battery Discharge Current
in Idle Mode
The MP2696B integrates three battery-charging
phases: pre-charge, constant current charge,
and constant voltage charge. This device also
manages the input power source through input
current limit regulation and minimum input
voltage regulation.
The MP2696B can switch to boost mode to
generate the system power output from the
battery.
Boost Converter with Up to 4.0A of Output
Current:
o Configurable Output Current Limit Loop
o Configurable Boost Output Voltage
o USB Output Cable Compensation
o Configurable Inductor Peak Current
Limiting
Comprehensive Safety Features:
o Fully Customizable JEITA Profile with
Configurable Temperature Threshold
o Charge Safety Timer
The MP2696B has an integrated IN to SYS
pass-through path to pass the input voltage to
the system.
Using an I2C interface, the host can flexibly
configure the charge and boost parameters.
The device operating status can also be read in
the registers.
Safety features include SYS short-circuit
protection (SCP), input over-voltage protection
(OVP), battery under-voltage protection (UVP),
thermal shutdown, and JEITA battery
temperature monitoring.
o Input Over-Voltage Protection (OVP)
o Thermal Shutdown
o SYS Over-Current (OC) and Short-
Circuit Protection (SCP)
Analog Voltage Output IB Pin for Battery
Current Monitoring
SYS Plug-In Detection
SYS No Load Detection
SYS DP/DM Interface for BC1.2 and Non-
Standard Adapters
The MP2696B is available in a QFN-21
(3mmx3mm) package.
