Product details
Overview
MP2770GL-0000-Z from Monolithic Power Systems is a highly integrated I²C-controlled 6A switching battery charger with power path management and 3.65A boost output for single-cell Li-ion/Li-polymer systems. It delivers up to 22.5W boost power, supports USB PD input current limiting (up to 3.5A), regulates charge voltage with ±0.5% accuracy across 3.65V–4.45V, and operates from 4V–16V input. It enables dual-role power delivery in portable power banks and USB-C PD accessories.
For engineers reviewing the MP2770GL-0000-Z datasheet, MP2770GL-0000-Z pinout, MP2770GL-0000-Z application, or MP2770GL-0000-Z equivalent, key selection criteria include its integrated IN→SYS pass-through path, configurable 3-phase charging (pre-charge/CC/CV), real-time I²C parameter tuning (VBST, IBST, IIN_LIMIT, VBATT_REG), and comprehensive JEITA-compliant thermal monitoring with 8-bit ADC telemetry.
Technical Context
The MP2770 implements a dual-path power architecture: during charge mode, it manages VIN-to-BATT charging while dynamically routing power to SYS via internal Q1 (5mΩ LS-FET) and Q2 (20mΩ PMID→SYS MOSFET); in boost mode, it converts BATT to programmable VBST (4.3V–16V) and powers SYS or IN using Q3 (10mΩ HS-FET) and Q4 (5mΩ LS-FET). Its I²C interface controls all critical parameters-including charge termination current (50–150mA), recharge threshold (4.7% below VBATT_REG), and input regulation clamp (4.44V/8.04V/11.04V).
It integrates a full safety stack: cycle-by-cycle overcurrent protection on all FETs, thermal regulation at 120°C with shutdown at 140°C, battery UVLO (2.5V/2.7V selectable), and dual-mode NTC monitoring-separate cold/hot thresholds for charge and boost modes-with 1.4% hysteresis per window. The 8-bit ADC monitors nine analog signals (VIN, VBATT, VSYS, VPMID, IQ1, IBATT, ISYS, VNTC, and NTC voltage) with 20–80mV LSB resolution.

Applications
| USB-C Power Banks | Smartphone/Tablet Docking Stations |
|---|---|
Use Scenario: Portable multi-port power bank supporting USB-C PD input and dual-output (USB-A + USB-C) with display charging. IC Role / Device Role / Timing Role: Manages bidirectional power flow: charges internal 3.7V Li-ion cell from 5–20V PD input while simultaneously boosting to 5V/9V/15V for downstream ports. Use Value: Enables 22.5W boost output at 9V/2.5A and 15V/1.5A with <95% efficiency; eliminates need for discrete boost controller + charger IC pair. | Use Scenario: Desktop dock providing video, data, and up to 60W power delivery to laptop while recharging its own internal battery. IC Role / Device Role / Timing Role: Acts as system PMIC: routes wall adapter power to laptop via USB-C PD contract negotiation while trickle-charging dock's backup battery. Use Value: Supports seamless transition between AC-powered and battery-powered operation with zero SYS interruption; reduces BOM count by integrating power path + ADC + thermal monitoring. |
| Industrial Handheld Terminals | Medical Wearables with Backup Power |
Use Scenario: Rugged handheld scanner with hot-swappable battery and always-on Ethernet/WiFi connectivity requiring >8hr runtime. IC Role / Device Role / Timing Role: Provides low-quiescent (12µA) standby mode, pre-charge for deeply discharged cells, and real-time battery health telemetry via I²C. Use Value: Extends field operational time via adaptive charge termination and temperature-aware JEITA profiles; enables predictive maintenance through ADC-monitored IBATT/VBATT trends. | Use Scenario: Patch-style ECG monitor with primary coin cell and secondary Li-ion backup, requiring fail-safe power switchover during clinical use. IC Role / Device Role / Timing Role: Serves as intelligent power arbitrator: powers system from coin cell during normal operation, switches to Li-ion only upon low-voltage detection or high-load demand. Use Value: Guarantees uninterrupted sensor operation during battery swap; prevents data loss via sub-100ms switchover and 200ms deglitch timers on recharge/termination events. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar switching battery charger with boost applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BQ25792RTWR | 4.5V–24V input; 5A max charge; no integrated boost converter; relies on external buck-boost for SYS power. | Lacks native boost output-requires additional IC and magnetics for dual-role power delivery. | Select when higher input voltage (>16V) or standalone charger functionality suffices without integrated boost. |
| IP2326 | 6A charge + 3.5A boost; no I²C interface; fixed register settings programmed at factory; no ADC telemetry. | Minimal firmware integration needed but lacks real-time parameter adjustment or health monitoring. | Select for cost-sensitive, high-volume consumer power banks where configurability and diagnostics are secondary. |
Compared with BQ25792RTWR and IP2326, MP2770GL-0000-Z uniquely combines 6A charging, 3.65A programmable boost, full I²C configurability, and integrated 8-channel ADC-enabling single-chip power management for complex USB PD accessories without external support ICs.

FAQ
What is the default I²C address of MP2770GL-0000-Z?
The default I²C slave address is 0x6B (7-bit), with SCL/SDA pins pulled up to 1.8V logic. Address can be changed via hardware strapping only on non-production variants; MP2770GL-0000-Z uses fixed 0x6B and supports standard-mode (100kHz) and fast-mode (400kHz) communication.
Does MP2770GL-0000-Z support USB PD 3.0 programmable power supply (PPS)?
No-it does not implement PPS negotiation. It supports USB PD input current limiting (IIN_LIMIT) and voltage clamping (VIN_MIN), but PPS handshake and dynamic voltage adjustment require an external PD controller (e.g., CYPD3177) communicating with MP2770 via I²C to update VBST and IBST registers.
Can MP2770GL-0000-Z operate without an external NTC thermistor?
Yes-NTC monitoring is optional. Pins NTC and VNTC may be left unconnected or tied to AGND to disable thermal protection. However, battery UVLO, OVP, OCP, and thermal shutdown remain active; JEITA profiles are bypassed but basic safety functions persist.
What is the maximum supported inductor value for MP2770GL-0000-Z in boost mode?
The recommended inductor range is 1µH–2.2µH (typical DCR ≤6mΩ). At 3.65A boost load, inductance >2.2µH increases conduction loss and reduces efficiency above 12V VBST; 1µH provides optimal transient response and 94%+ efficiency at 5V/3.65A with 3V battery input.
How does MP2770GL-0000-Z handle simultaneous charge and boost operation?
It does not support true simultaneous operation. When boost is enabled, charging halts automatically. The device enforces exclusive mode: either charge mode (IN→BATT+SYS) or boost mode (BATT→SYS/IN), controlled by I²C register bit BOOST_EN and monitored via STATUS register.
Is the 12µA standby current measured with ADC and I²C disabled?
Yes-the 12µA quiescent current is specified with VIN absent, SYS unplugged, ADC disabled, and I²C interface inactive. Enabling ADC or maintaining I²C bus activity increases current draw to ~2mA in boost-suspended state.
What PCB layout guidance applies to the PGND and AGND connections?
PGND and AGND must connect at a single point near the IC's thermal pad. PGND carries high-switching currents (IN, BATT, SYS, PMID); AGND is reserved for analog circuits (ADC, VNTC, SCL/SDA). A 0.3mm-wide isolation gap separates the planes until the star point, preventing noise coupling into sensitive measurements.
