The bq24728 is a high-efficiency, synchronous battery charger, offering low component count for space-constraint, multi-chemistry battery charging applications. The device uses two charge pumps to  separately drive n-channel MOSFETs (ACFET, RBFET and BATFET) for automatic system power source selection. SMBus controlled input current, charge current, and charge voltage DACs allow for high regulation accuracies that can be programmed by the system power management micro-controller.

MIP2F3 Datasheet – High-performance IPD for Battery Charger

Part Number : MIP2F3

Function : High-performance IPD designed for 20W battery charger

Package : DIP 7 Pin Type

Manufactures : Panasonic


MIP2F3 datasheet


MIP2F×series is a high-performance IPD designed for 20W battery chargers. It features built-in protection circuits necessary for compact power source charger circuitry. This allows a significant reduction in externally connected parts.

It provides PWM control when a normal load is applied and intermittent control with low load. This results in greater efficiency for very low to maximum loads, while also conserving power during standby.


1. Reduction of input voltage dependency
2. Significantly reduce no-load power consumption
(At 100 V AC input: 20 mW, at 240 V AC input: 20 mW)
3. Built-in protection function required for charger circuit
