Introduction

The MP2617AGL-P is a highly integrated DC-DC battery charging controller designed for modern Li-ion battery applications. This device integrates high-side and low-side current sense amplifiers, low-dropout voltage regulator, a precision voltage differential amplifier, and an I2C/SMBus interface. Beyond the safety features, the MP2617AGL-P also reduces system cost and board space by eliminating the need for discrete current sense resistors and Op-Amps.

Functionality

The MP2617AGL-P can be used to realize a wide variety of charge-at-once, charge-on-the-go, and other AC/DC, DC/DC and mixed-mode Li-ion battery charging applications. As a central switch in a portable system\'s power supply, the MP2617AGL-P supports the following battery charger operations:

• Charge with four-level switch, 4-levels control, or voltage tracking regulation.
• Select from either constant current/constant voltage charger modes.
• Monitor and control voltage, current, and temperature of the battery.
• Programmable fast/trickle charge and timer.
• Supports almost all Li-ion primary and secondary batteries.

Power Supply Design Requirements

To achieve the best trickling and fast charging, the MP2617AGL-P requires an input power supply design. A low RdsOn switch and low input and output resistances are preferable in order to reduce energy loss and to control the Li-ion battery charging process more accurately. The device needs an output capacitor, preferably with a very low ESR and low ESL values, to ensure minimum 3.2 A output current. This device is also equipped with a piece wise linear, low drop-out (LDO) regulator which needs an input capacitor for proper working. This capacitor needs to be placed as close as possible to the package in order to minimize output ripple.
