The MP2633A is a highly-integrated, flexible, switch-mode battery charge management and system power path management device for a single-cell Li-ion and Li-Polymer battery used in a wide range of portable applications.
The MP2633A has two operating modes—charge mode and boost mode—to allow management of system and battery power based on the state of the input.
When input power is present, the device operates in charge mode. It automatically detects the battery voltage and charges the battery in the three phases: trickle current, constant current and constant voltage. Other features include charge termination and auto-recharge. This device also integrates input current limit in order to manage input power and meet the priority of the system power demand. .
In the absence of an input source, the MP2633A switches to boost mode through the MODE pin to power the SYS pins from the battery. The OLIM pin programs the output current limit in boost mode. The MP2633A also allows an output short-circuit thanks to an output disconnect feature, and can auto-recover when the short circuit fault is removed.
The MP2633A provides full operating status indication to distinguish charge mode from boost mode.
The MP2633A achieves low EMI/EMC performance with well-controlled switching edges.
To guarantee safe operation, the MP2633A limits the die temperature to a preset value 120oC. Other safety features include input over-voltage protection, battery over-voltage protection, thermal shutdown, battery temperature monitoring, and a programmable timer to prevent prolonged charging of a dead battery.

EV2633A-R-00A Evaluation Kit Full Power Management IC For Single-Cell Battery System
The EV2633A-R-00A is the evaluation board designed to demonstrate the capabilities of MPS’ MP2633A, a highly-integrated, flexible switch-mode battery charge management and system power path management device for a single-cell Li-ion and Li-Polymer battery used in a wide range of portable applications.
EV2633A uses two operation modes -- charge mode and boost mode -- to allow management of system and battery power based on the state of the input.
When input power is present, the board charges a single-cell battery with a programmable charge current of up to 1.5A.
In the absence of an input source, the board switches to boost mode through the MODE pin to power the SYS pins from the battery with a current up to 1A.
The evaluation board provides full-operating-status indication to distinguish charge mode from boost mode.
For guaranteed safe operation, the EV2633A has input-over-voltage protection, battery over-voltage protection, thermal shutdown, battery-temperature monitoring, and programmable timer to prevent prolonged charging of a dead battery.
