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) stepdownregulator switch at 2MHz, allowing the use of smallmagnetic components. The output voltages for SD0 andSD1 are programmable from 0.26V to 1.52V in 10mVsteps. The output voltage for SD2 is programmable from0.6V to 2.194V in 6.5mV steps. The output voltage for SD3is programmable from 0.6V to 3.78V in 12.5mV steps.Nine low-dropout (LDO) linear regulators supply power tovarious system blocks. Each LDO features a programmableactive-discharge circuit in shutdown. All LDOs featuretwo soft-start rates to limit inrush current during start up.Eight programmable GPIOs can be programmed as generalpurpose inputs (GPI), general purpose outputs(GPO), or alternate modes for additional functionalities.The real-time clock (RTC) with an external crystal oscillatorprovides time keeping and alarm wake-up functions.An internal silicon oscillator is available for systems thatdo not want to use the crystal oscillator. In addition, awatchdog timer is integrated for system monitoring purposes.An integrated ON/OFF controller, in combination with flexiblepower sequencer (FPS), provides maximum flexibilityin setting power-up/down sequences with minimal interventionfrom the applications processor.The 70-bump, 4.1mm x 3.25mm x 0.7mm, 0.4mm pitchwafer-level package (WLP) is ideal for space constrainedapplications.Factory-programmable options allow the MAX77714 to betailored for many applications.
