[Outline]
The MM3556 is installed on boards within products that operate using batteries.
The MM3556 measures the voltage and temperature of battery packs to predict the relative charging rate %. The relative charging rate % under various conditions can be predicted smoothly and with a high level of precision using Mitsumi's proprietary algorithms.
This helps extend the continuous operating time of mobile devices. Current detection resistant is not required, and the built-in thermistor temperature detection circuit and OTP memory help to reduce battery level detection costs of mobile devices.


[Features]
1. 
Remaining battery level is calculated very precisely and smoothly only with voltage and temperature
2. 
Current sensing resistor is not required and the cost and space can be reduced
3. 
Detection circuit of thermistor temperature in battery pack incorporated
4. 
Parameter can be stored in built-in OTP
