Product details
Overview
MAX77714EWC+ from Analog Devices is a highly integrated power-management IC (PMIC) 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 oscillator support, flexible power sequencer, and backup battery charger. Key confirmed specs: 2MHz switching frequency, 0.26V–1.52V DVS range on SD0/SD1, 85μA sleep-mode IQ, and 70-bump 0.4mm-pitch WLP package.
For engineers reviewing the MAX77714EWC+ datasheet, MAX77714EWC+ pinout, MAX77714EWC+ application, or MAX77714EWC+ equivalent, this page delivers verified regulator configurations, GPIO alternate-mode mapping, FPS timing control parameters, RTC alarm wake-up behavior, and factory-programmable OTP options - all critical for SoC power architecture validation and layout-sensitive PMIC integration.
Technical Context
The MAX77714EWC+ implements a hierarchical power architecture: four independent buck regulators operate at 2MHz with dynamic voltage scaling (DVS) and active discharge; nine LDOs include NMOS/PMOS variants with dual soft-start rates and programmable discharge. The flexible power sequencer (FPS) enables user-defined power-up/down/sleep entry/exit timing across up to four resources without host processor intervention.
Its real-time clock supports both external 32.768kHz crystal and internal silicon oscillator modes, with alarm interrupt and sudden momentary power loss (SMPL) detection. The I²C interface (7-bit slave address 0x48) provides full register-level control of all regulators, GPIOs, FPS, and RTC functions - essential for runtime power state orchestration in Android/Linux-based platforms.

Pinout & Package
MAX77714EWC+ uses a 70-bump wafer-level package (WLP) measuring 4.1mm × 3.25mm × 0.7mm with 0.4mm ball pitch. The bump configuration is defined in the official datasheet (Rev 4, p.37–39) and includes dedicated power inputs (IN, IN_LDO0_1, IN_LDO2, etc.), regulator outputs (VSD0–VSD3, OUT_LDO0–OUT_LDO8), GPIOs (GPIO0–GPIO7), and system control signals (nRST_IO, nIRQ, SCL, SDA, XIN/XOUT).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN | Main input supply (2.5V–5.5V) | Primary power source for all buck regulators and bias circuitry |
| VSD0–VSD3 | Buck regulator outputs | Deliver regulated voltages to SoC cores, GPU, memory, and peripherals per DVS settings |
| OUT_LDO0–OUT_LDO8 | LDO outputs | Provide low-noise, low-dropout supplies for sensors, audio codecs, RF front-ends, and camera modules |
| GPIO0–GPIO7 | Programmable I/O terminals | Configurable as GPI/GPO or ALT modes (e.g., 32kHz output, FPS control, ACOK input) |
| nRST_IO | Bidirectional reset I/O | Supports both system-initiated reset assertion and external reset monitoring with pull-up/pull-down control |
| XIN/XOUT | Crystal oscillator interface | Connects to 32.768kHz tuning-fork crystal for RTC timekeeping and alarm wake-up |
| nIRQ | Interrupt output | Open-drain signal indicating regulator faults, RTC alarms, thermal events, or GPIO-triggered interrupts |
Key Features
| Feature | Design Value |
|---|---|
| Flexible Power Sequencer (FPS) | Four independently configurable FPS outputs enable precise power-up/down/sleep timing sequences without CPU involvement - critical for SoC boot reliability |
| RTC with SMPL detection | Retains time/date during main power loss using backup battery; detects sub-100ms interruptions and triggers recovery actions |
| Factory OTP programming | Enables permanent configuration of default voltages, FPS timing, GPIO modes, and power-on behavior - eliminates runtime initialization overhead |
| Dual soft-start for LDOs | Selectable fast/slow ramp rates limit inrush current during startup - prevents input rail droop in multi-rail systems |
| Active discharge on all LDOs | Programmable discharge resistors ensure rapid output voltage decay during shutdown - avoids floating nodes and improves system safety |
| Backup battery charger | Linear charger supports 3V–4.2V Li-ion/Li-poly backup cells with thermal foldback and charge status reporting via I²C |

FAQ
What is the maximum supported input voltage for MAX77714EWC+?
The MAX77714EWC+ supports an absolute maximum input voltage of 5.5V on its main IN supply pin. Operation is specified over 2.5V to 5.5V, with optimal efficiency achieved at typical battery voltages (3.0V–4.5V). Exceeding 5.5V risks permanent damage to internal FETs and regulators.
Does MAX77714EWC+ support dynamic voltage scaling (DVS) on all buck regulators?
Yes, MAX77714EWC+ supports DVS on SD0 and SD1 (0.26V–1.52V in 10mV steps), enabling real-time voltage adjustment for CPU/GPU DVFS. SD2 and SD3 offer fixed-output or programmable-voltage operation but lack full DVS capability - their ranges are 0.6V–2.194V (6.25mV steps) and 0.6V–3.78V (12.5mV steps), respectively.
How many GPIOs does MAX77714EWC+ provide, and what alternate functions are supported?
The MAX77714EWC+ provides eight fully programmable GPIOs (GPIO0–GPIO7). Confirmed alternate functions include three 32kHz oscillator outputs, four FPS control signals, and one ACOK input - all configurable via I²C registers without hardware changes.
Can MAX77714EWC+ operate without an external crystal?
Yes, MAX77714EWC+ includes an internal silicon oscillator that can replace the external 32.768kHz crystal for RTC operation. While crystal mode offers higher accuracy (±20ppm), the internal oscillator supports ±5% accuracy - sufficient for non-precision timekeeping applications like system wake-up timers.
What thermal protection features are implemented in MAX77714EWC+?
MAX77714EWC+ integrates a thermal monitor with automatic shutdown at +125°C junction temperature and hysteresis-based recovery at +110°C. Thermal status is reported via dedicated interrupt flag and readable register bits, allowing host firmware to initiate throttling or graceful shutdown before critical overheating occurs.
