MAX8594A - 5-Output PMICs with DC-DC Core Supply

Download the MAX8594A datasheet PDF. This datasheet also covers the MAX8594 variant, as both devices belong to the same 5-output pmics with dc-dc core supply family and are provided as variant models within a single manufacturer datasheet.

General Description

The MAX8594/MAX8594A complete power-management chips for low-cost personal digital assistants (PDAs) operates from a 1-cell lithium-ion (Li+) or 3-cell NiMH battery.

Key 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 ensure an orderly start. In addition, the COR1 regulator is not started until the 3.3V main output is in regulation. Also included are a 1% accurate reference and low-battery monitor. Thermal shutdow.

19-3349; Rev 2; 4/05 www.DataSheet4U.com 5-Output PMICs with DC-DC Core Supply for Low-Cost PDAs General Description The MAX8594/MAX8594A complete power-management chips for low-cost personal digital assistants (PDAs) operates from a 1-cell lithium-ion (Li+) or 3-cell NiMH battery. They include all regulators, outputs, and voltage monitors necessary for small portable devices while requiring a bare minimum of external components. Featured are three linear regulators, a boost DCDC converter for LCD bias, an efficient 4MHz buck DC-DC converter for core power, a microprocessor (µP) reset output, and low-battery shutdown in a 0.8mm high thin QFN package. The COR1 buck DC-DC converter supplies a pin-selectable output at 400mA.
