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.  
Status and Fault Monitoring  
Available in a QFN-21 (3mmx3mm)  
Package
