Overview

The MP2759GQ-0000-P is a switching battery charger IC from Monolithic Power Systems rated for use with battery systems up to 36 V and charge currents up to 3 A. It implements a switch-mode charging topology intended for charging multi-cell battery packs while minimizing heat compared with linear solutions. The device is aimed at designers who need a compact, higher-voltage charging solution for portable and industrial battery-powered products.

Why Choose This Part

A switch-mode charger IC like this offers higher efficiency and lower thermal dissipation than comparable linear chargers, which eases thermal design. Its 36 V voltage capability and 3 A charge rating support medium-voltage battery packs and moderate charge rates. Using a dedicated charger IC reduces component count and PCB area compared with discrete regulator-based chargers.

Applications

E-bike and e-scooter battery charging
Charging multi-cell lithium battery packs used in small electric vehicles where pack voltages approach 36 V.
Cordless power tools
On-bench or bench-top chargers for medium-voltage tool battery packs requiring moderate (around 3 A) charge currents.
Portable UPS and backup power
Charging battery packs used in compact uninterruptible power supplies and backup systems for network or industrial equipment.
Industrial portable equipment
Battery charging inside portable measurement, sensing, or communications gear that use multi-cell packs up to 36 V.

Getting Started

Start by downloading the MP2759 datasheet and any related application notes from Monolithic Power Systems, and look for a manufacturer evaluation board or reference design if available. Follow the recommended PCB layout and thermal guidelines, and validate charging behavior on the bench with a programmable power supply, electronic load, and an oscilloscope to check switching waveforms and stability.
