The MAX77714 is a complete power-management IC
(PMIC) for portable devices using System-on-Chip (SoC)
applications processors.
Two 2A (SD2/3), one 3A (SD1), and one 4A (SD0) stepdown
regulator switch at 2MHz, allowing the use of small
magnetic components. The output voltages for SD0 and
SD1 are programmable from 0.26V to 1.52V in 10mV
steps. The output voltage for SD2 is programmable from
0.6V to 2.194V in 6.5mV steps. The output voltage for SD3
is programmable from 0.6V to 3.78V in 12.5mV steps.
Nine low-dropout (LDO) linear regulators supply power to
various system blocks. Each LDO features a programmable
active-discharge circuit in shutdown. All LDOs feature
two soft-start rates to limit inrush current during start up.
Eight programmable GPIOs can be programmed as general
purpose inputs (GPI), general purpose outputs
(GPO), or alternate modes for additional functionalities.
The real-time clock (RTC) with an external crystal oscillator
provides time keeping and alarm wake-up functions.
An internal silicon oscillator is available for systems that
do not want to use the crystal oscillator. In addition, a
watchdog timer is integrated for system monitoring purposes.
An integrated ON/OFF controller, in combination with flexible
power sequencer (FPS), provides maximum flexibility
in setting power-up/down sequences with minimal intervention
from the applications processor.
The 70-bump, 4.1mm x 3.25mm x 0.7mm, 0.4mm pitch
wafer-level package (WLP) is ideal for space constrained
applications.
Factory-programmable options allow the MAX77714 to be
tailored for many applications. Contact the factory for
more information about programmable options; minimum
order quantities may apply.
