製品説明

The EV2635B-R-00A is the evaluation board designed to demonstrate the capabilities of MPS’ MP2635B, 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.

EV2635B uses 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 board charges a single-cell battery with a programmable charge current of up to 2. 0A.

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 of up to 1.5A.

The evaluation board provides full-operating-status indicators to distinguish charge mode from boost mode.

To guarantee safe operation, the EV2635B has 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.

2A Single Cell Switching Charger with Power Path Management and 1.5A BOOST OTG

The MP2635 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 MP2635 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 both input current limit and input voltage regulation in order to manage input power and meet the priority of the system power demand.
In the absence of an input source, the MP2635 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 MP2635 also allows an output short-circuit thanks to an output disconnect feature, and can auto-recover when the short circuit fault is removed.
The MP2635 provides full operating status indication to distinguish charge mode from boost mode.
The MP2635 achieves low EMI/EMC performance with well-controlled switching edges.
To guarantee safe operation, the MP2635 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.
The MP2635 has two battery full options. MP2635: 4.2V/3.6V; MP2635B: 4.35V/4.2V.
