1. Description

Management for

Mobiles (PM)

The AT73C214 is designed to supply digital, analog, interface, RF and backup sec-

tions of generic wireless devices and in particular battery powered applications. It can

be used to supply a CPU with a high efficiency DC-to-DC Converter, Radio Frequency

transceivers with high PSRR and noise performance LDOs, Memories and Analog

Sections with independent LDO channels.

Power

In addition the AT73C214 integrates LDOs to recharge backup elements and convert

voltage to microcontroller RTC supply.

The AT73C214 also includes a low-cost battery charger, using a simple external PNP

transistor for Li-Ion or Li-Polymer batteries. The battery-safe operating conditions are

fully under hardware control during the start up procedure (i.e., when the device is

turned on or a charger is plugged in). The battery precharge is integrated and self

operated by the AT73C214. Then the fast-charge phase and end-of-charge procedure

are transferred to the external microcontroller software.

Devices

LDO and DC-to-DC output voltage can be programmed by mask change.
