Wireless Power Management Integrated Circuit

The MC13181 Wireless Power Management Integrated Circuit (PMIC) is a monolithic IC designed for hand-held electronics products in conjunction with the Motorola Bluetooth chipset (the MC13180 Bluetooth Radio and MC71000 Bluetooth Protocol Controller) or stand-alone in other products. The MC13181 is ideal for devices operating from a 3.6 V single-cell Lithium-ion battery or other energy systems in the 2.85 to 6.5 V range.
