Sequencing for Multicore Applications General Description Benefits and Features The MAX77714 is a complete power-management IC
(PMIC) for portable devices using System-on-Chip (SoC)
applications processors. в—Џ Highly Integrated 4x Buck Regulators SD0/1 Peak Efficiency >90% at 3.6VIN,1.1VOUT SD2/3 Peak Efficiency >93% at 3.6VIN,1.8VOUT Supports LDDR4x Memory requirements 9x Low-Dropout Linear Regulator Eight GPIOs Real-Time Clock Backup Battery Charger Bidirectional Reset I/O Interrupt Output System Watchdog Timer 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.
