Description
19-3349; Rev 2; 4/05 www.DataSheet4U.com 5-Output PMICs with DC-DC Core Supply for Low-Cost PDAs General .
The MAX8594/MAX8594A complete power-management chips for low-cost personal digital assistants (PDAs) operates from a 1-cell lithium-ion (Li+) or 3-cel.
Features
* an onboard MOSFET and True Shutdown™ when off. This means that during shutdown, input power is disconnected from the inductor so the boost output falls to 0V rather than remaining one diode drop below the input voltage. A µP reset output clears 20ms (typ) after the COR1 output achieves regulation to
