Product details
Overview
MAX77714EWC+T from Analog Devices is a highly integrated power-management IC (PMIC) designed for multicore SoC applications in space-constrained portable devices. It integrates four buck regulators (4A/3A/2A/2A), nine LDOs, eight programmable GPIOs, RTC with crystal or silicon oscillator, flexible power sequencer, watchdog timer, and backup battery charger. Key confirmed parameters: 2MHz switching frequency, 0.26V–1.52V DVS range on SD0/SD1, 85μA sleep IQ, and 70-bump 4.1mm × 3.25mm WLP package - enabling compact smartphone and AR/VR headset power architectures.
For engineers reviewing the MAX77714EWC+T datasheet, MAX77714EWC+T pinout, MAX77714EWC+T application, or MAX77714EWC+T equivalent, this page delivers verified regulator output ranges, FPS timing configuration, GPIO alternate-mode mapping, RTC alarm wake-up capability, and factory-programmable OTP options - all essential for SoC power rail bring-up and system-level power sequencing validation.
Technical Context
The MAX77714EWC+T implements a hierarchical power architecture: four synchronous step-down regulators operate at 2MHz with independent DVS control (SD0/SD1: 10mV steps; SD2: 6.25mV; SD3: 12.5mV), while nine LDOs provide low-noise biasing with dual soft-start rates and active discharge. Its Flexible Power Sequencer (FPS) supports four configurable resources with user-defined power-up/down/sleep entry/exit delays, decoupled from host processor intervention.
Real-time clock functionality includes external 32.768kHz crystal support (with internal ballast capacitors) or standalone silicon oscillator mode; the bidirectional nRST_IO pin enables system reset coordination, and the I²C interface (7-bit slave address 0x48) provides full register-level control of all power resources, GPIO modes, and interrupt masking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Step-down Regulators | SD0: 4A, SD1: 3A, SD2/SD3: 2A each - supports high-current SoC cores and memory rails with minimal external components |
| Output Voltage Range (SD0/SD1) | 0.26V–1.52V in 10mV steps - enables precise DVS for ARM big.LITTLE or heterogeneous CPU clusters |
| Switching Frequency | 2MHz - allows use of ≤1μH inductors and compact ceramic output capacitors |
| Sleep Mode Quiescent Current | 85μA total - extends battery life during system suspend in always-on sensor or connectivity subsystems |

| I²C Interface | Standard-mode (100kHz) and fast-mode (400kHz) compatible, fixed 7-bit address 0x48 - enables direct integration with Linux kernel regmap-i2c drivers |
Pinout & Package
The MAX77714EWC+T uses a 70-bump wafer-level package (WLP) measuring 4.1mm × 3.25mm × 0.7mm with 0.4mm pitch, arranged in a 10×7 ball array. Bump assignment follows Analog Devices' standardized configuration per datasheet Rev 4 (2023), with dedicated power, ground, feedback, enable, and I/O balls.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN_SD0 / IN_SD1 / IN_SD2 / IN_SD3 | Main input supply pins for respective buck regulators | Accept 2.5V–5.5V input; require local ceramic decoupling (≥10μF) to minimize voltage ripple during load transients |
| LX_SD0 / LX_SD1 / LX_SD2 / LX_SD3 | Switch node outputs | Connect to external inductor; routing must minimize loop area to reduce EMI and switching losses |
| FB_SD0 / FB_SD1 / FB_SD2 / FB_SD3 | Feedback inputs for output voltage regulation | Resistive divider sets output voltage; precision resistors (0.5% tolerance) required for DVS accuracy |
| PG_SD0 / PG_SD1 / PG_SD2_3 | Power-good status outputs | Open-drain signals indicate regulated output stability; used for sequenced enable of downstream rails |
| SDA / SCL / nIRQ | I²C data, clock, and interrupt output | nIRQ asserts low on fault or event (e.g., thermal shutdown, RTC alarm); requires external pull-up |
| nRST_IO | Bidirectional reset I/O | Can drive or monitor system reset line; internal weak pull-up enables master-initiated reset assertion |
| XIN / XOUT | Crystal oscillator connections | Supports 32.768kHz tuning-fork crystal; internal load caps eliminate need for external capacitors |
| GPIO0–GPIO7 | Programmable general-purpose I/O | Configurable as GPI, GPO, or ALT modes (e.g., 32k_OUT, FPS_OUT, ACOK_IN); software-controlled pull-up/down |
Key Features
| Feature | Design Value |
|---|---|
| Flexible Power Sequencer (FPS) | Four independently configurable FPS outputs with programmable delay (0–2.55s), enabling deterministic power-up/down/sleep transitions without firmware involvement |
| Dual Soft-Start for LDOs | Two selectable ramp rates per LDO - fast start for non-critical rails, slow start to limit inrush into large capacitive loads |
| Active Discharge on All LDOs | Programmable discharge path discharges output capacitors during shutdown - prevents floating voltages and ensures clean power-down sequencing |
| RTC with Dual Oscillator Options | Supports either external 32.768kHz crystal (±20ppm accuracy) or internal silicon oscillator (±5% accuracy) - balances precision vs. BOM count |
| Backup Battery Charger | Linear charger for coin-cell batteries (VBAT = 2.5–4.5V); provides RTC backup during main power loss with automatic switchover |
| Factory OTP Configuration | One-time programmable options include default FPS timing, GPIO power-on states, and LDO enable sequences - reduces boot-time initialization overhead |

FAQ
What is the maximum supported input voltage for the MAX77714EWC+T buck regulators?
The MAX77714EWC+T buck regulators accept an input voltage range of 2.5V to 5.5V on their respective IN_SDx pins. This range accommodates common single-cell Li-ion (3.0V–4.35V) and USB-powered (5V) systems. Exceeding 5.5V violates absolute maximum ratings and may cause permanent damage to the MAX77714EWC+T. Input voltage must be stabilized with appropriate bulk and high-frequency ceramic capacitors per the layout guidelines in the datasheet.
Does the MAX77714EWC+T support dynamic voltage scaling (DVS) on all buck regulators?
Yes, the MAX77714EWC+T supports DVS on SD0 and SD1 only, with programmable output voltages from 0.26V to 1.52V in 10mV steps. SD2 and SD3 have fixed or coarser programmability (SD2: 0.6V–2.194V in 6.25mV steps; SD3: 0.6V–3.78V in 12.5mV steps) and are not optimized for rapid DVS transitions. DVS on SD0/SD1 is controlled via I²C register writes and synchronized with FPS events to avoid race conditions during SoC frequency scaling.
How many GPIOs does the MAX77714EWC+T provide, and what alternate functions are available?
The MAX77714EWC+T provides eight fully programmable GPIOs (GPIO0–GPIO7). Each can be configured as GPI, GPO, or one of multiple alternate functions including FPS_OUT0–3, 32k_OUT0–2, ACOK_IN, and THERM input. Alternate mode selection is performed via I²C-accessible GPIO programming matrix registers (e.g., GPIO_ALT0–GPIO_ALT7), allowing flexible system-level signal routing without additional logic components.
What RTC backup options does the MAX77714EWC+T support?
The MAX77714EWC+T supports two RTC backup sources: an external 32.768kHz crystal connected to XIN/XOUT (enabling ±20ppm accuracy) or an internal silicon oscillator (±5% accuracy, no external components). A dedicated BBATT pin accepts 2.5V–4.5V backup battery input (e.g., CR1220), and the integrated linear charger maintains charge level during main power operation. The RTC retains time and alarms across main power loss using the selected backup source.
Is the MAX77714EWC+T pin-compatible with other devices in the MAX777xx family?
No, the MAX77714EWC+T is not pin-compatible with other MAX777xx devices such as MAX77757 or MAX77705. Its 70-bump WLP layout, bump assignment, and functional resource mapping (e.g., FPS outputs, GPIO ALT modes) are unique to the MAX77714EWC+T. Migration requires PCB redesign and firmware adaptation. Always verify bump configuration and register map compatibility before substituting any MAX777xx part.
