1 / 18 page MC13181 Ordering Information Device Marking Package MC13181R2 13180 QFN-24 Package Information Plastic Package Case 1307 (QFN-24) (Scale 2:1) This document contains information on a pre-production product. Specifications and Pre-production information herein are subject to change without notice. © Motorola, Inc., 2002. All rights reserved. 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 Vih levels from 1.5 V to VCC. 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 in one package Advance Information MC13181/D Rev. 0, 08/2002 Wireless Power Management Integrated Circuit |
