All < MM3538/MM3618/MM3582 > models feature a built-in load switch with overvoltage detection function and input current limit required for system paths, and built-in power FETs, backflow prevention diodes, and current sensor function required for charging and discharging. The use of a WLCSP package minimizes mounting area. Additionally, as well as being compatible with the JEITA recommended battery temperature profile, these models are also compatible with various battery pack specifications, and safety is also taken into consideration with the use of a lithium ion battery.
The < MM3538/MM3618 > models come equipped with an adapter and USB automatic recognition function to help reduce parts cost of the overall set. In addition to providing the individual settings for charging control voltage and current with I²C communication, they also include the freedom of set designs by allowing various settings to be configured.
< MM3538/MM3618 > have different types of voltage detection and charging ON/OFF terminal configurations, allowing the optimum model to be chosen to suit the set. < MM3582 > is a stand-alone type that does not feature the I²C communication function.

1.	Allows the power management and battery charge/discharge of mobile devices to be controlled using a single IC (same for all models)
2.	Comes equipped with a USB input current limit, as well as battery support mode that also supplies power from the battery automatically when there is insufficient USB current capability (same for all models)
3.	I2C communication allows checks and settings of various conditions (MM3538/MM3618) Current and frequency can be set using only external resistance and capacity (MM3582)
4.	Comes with power input, system output, and battery charging status output flag terminals. This allows the condition to be checked easily from external devices (same for all models)
