Total Power Management IC (PMIC) for Computationally Intensive for Mobile Platforms Using SoC Application Processors


Please check latest availability status for a specific part variant.

Description

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.
