3 Description The

MX4131 is a single chip protection solution specially designed for 1-cell Li+ rechargeable battery pack application. Also it integrates highly accurate detection circuits and detection delay circuits to prevent batteries from over-charging, over-discharging, over-current discharging and over-current charging. The MX4131 consumes very low standby current for cell longtime storing. The integrated low-Rdson MOSFET ensures that battery delivers the maximum power. The device is not only targeted for digital cellular phones, but also for any other Li-Ion and Li-Poly battery-powered information appliances requiring longterm battery. The MX4131 is available in SOT23-5 package.
