Description
The MP26123 is a monolithic DC-DC step-down switching charger for Li-ion battery packs with two or three cells. It contains an inbuilt high-side power MOSFET that can deliver up to 2A of charging current. It also incorporates peak-current control for quick loop response and simple correction. The MP26123 controls a programmable charge current with a sensing resistor and properly regulates the charge current and voltage using two control loops. The MP26123 features a number of fault state safeguards‚ including cycle-by-cycle current limiting and thermal shutdown. Other safety features include battery temperature monitoring and protection‚ charge status indication‚ and a programmed timer that automatically stops the charging cycle when the timer expires.
Features:
- It charges two or three battery cell Li-Ion
- Its programmable charging current up to 2A
- Its highly efficient
- Its efficiency up to 90%
- Battery Temperature Monitor and Protection
