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. The IC
features three independently enabled Low Drop Out (LDO) Linear Voltage Regulators for
powering baseband, audio, RF/IF, and interface circuitry. A comparator with logic-enabled
hysteresis and one scaled input is provided for use as a low-battery detector to protect against
destructive battery discharge; it can alternately be used for general system interfacing. A
supervisory circuit is integrated to provide a reset signal to the Protocol Controller indicating
valid supply. An over-temperature shutdown function is integrated to protect against
excessive power dissipation. A Shutdown input line is provided to allow for disabling of all
active circuitry to minimize battery loading and to provide single line master disable. Logic
inputs accept V_ih levels from 1.5 V to V_CC.
Typical Applications
• Add-On Bluetooth Adaptor Cards for Cellular Phones
• Cellular Phones
• USB Dongle
• GPS or PDA
• Cordless Headsets
• Other portable devices requiring multiple independent regulators
