The Future of Analog IC Technology
DESCRIPTION
The MP26029 is a highly integrated, single-cell Li-ion/Li-polymer battery charger IC with thermal regulation. The MP26029 is able to charge the battery by using either an AC adapter (up to 13V) or USB port. The MP26029 also features precharge, high-accuracy constant-current charge (CC, up to 1A) and constant-
voltage (CV) regulation, charge termination, and autorecharge.
The MP26029 has input
voltage limit function. In case the CC current exceeds the current rating of input power, the MP26029 will decrease the charge current automatically once the input
voltage reaches the input
voltage limit.
The MP26029 has a NTC pin to monitor the battery temperature via a negative temperature coefficient (NTC) thermistor, once the battery temperature is out of cold/hot window the charging will be suspended.
The MP26029 also has One-time-program (OTP) function to program the parameters like battery full
voltage, termination current, input
voltage limit, input OVP threshold, thermal regulation threshold and so on.
The MP26029 is available in 6-pin SOT563, 8pin SOIC8 EP, and 10-pin QFN (3mmx3mm) packages.
