Monolithic Power Systems Inc. MP2770GL-0000-P

Overview

MP2770GL-0000-P from Monolithic Power Systems is a highly integrated I²C-controlled 6A single-cell Li-ion/Li-polymer switching charger with bidirectional power path management and 3.65A boost output. It delivers configurable charge regulation (4.3V–4.45V, ±0.5%), supports USB PD input current limiting (up to 3.5A), and provides system power via SYS/PMID during charging or boost mode. It is deployed in portable power banks requiring simultaneous charge and system supply with thermal and battery safety monitoring.

For engineers reviewing the MP2770GL-0000-P datasheet, MP2770GL-0000-P pinout, MP2770GL-0000-P application, or MP2770GL-0000-P equivalent, key selection considerations include its dual-mode operation (charge + boost), real-time I²C parameter reconfiguration (VBST, IBST, IIN_LIMIT, VBATT_REG), integrated 8-bit ADC for VIN/VBATT/VSYS/NTC monitoring, and JEITA-compliant battery temperature supervision across charge and boost modes.

Technical Context

The MP2770 implements a four-MOSFET power path architecture with independent control of Q1 (IN→PMID), Q2 (PMID→SYS), Q3 (HS-FET), and Q4 (LS-FET), enabling seamless transition between charge, pass-through, and boost modes. Its I²C interface configures all critical operating parameters-including VBST (4.3V–16V, 20mV/step), IBST (0.5A–3.65A, 50mA/step), and IIN_LIMIT (0.5A–3.5A)-without external resistor networks.

It integrates an 8-bit ADC measuring seven analog signals (VIN, VBATT, VSYS, VPMID, IQ1, IBATT, ISYS, NTC) and supports customizable JEITA profiles for battery temperature monitoring in both charge and boost modes, with programmable cold/warm/hot thresholds referenced to VNTC (1.28V).

FAQ

What is the factory-default I²C configuration for MP2770GL-0000-P?

The "0000" suffix indicates the factory-default register configuration: VBST = 5.0V, IBST = 0.5A, IIN_LIMIT = 0.5A, VBATT_REG = 4.20V, and JEITA temperature thresholds set to default cold/warm/hot windows. These values can be modified in-system via I²C write commands without reflashing firmware.

Does MP2770GL-0000-P support USB PD communication directly?

No-it does not implement USB PD protocol negotiation. It supports USB PD *power delivery* by accepting standardized PD voltages (5V/9V/12V/15V) and enforcing configured IIN_LIMIT settings. A separate USB PD controller (e.g., CYPD3177) is required for CC communication and voltage negotiation.

Can MP2770GL-0000-P operate without an NTC thermistor?

Yes-NTC monitoring is optional and disableable via I²C register. When disabled, thermal regulation and shutdown remain active using die temperature sensing. However, JEITA-compliant battery temperature profiling requires the NTC network connected to NTC/VNTC pins.

What is the maximum continuous boost output power achievable?

At 3.65A and 12V VBST, MP2770GL-0000-P delivers up to 43.8W peak, but continuous output is limited by thermal design. With proper PCB layout (2 oz copper, thermal vias to inner layers), sustained 22.5W (e.g., [email protected]) is achievable at TA = 50°C per typical efficiency curves in the datasheet.

How does the MP2770 handle input disconnection during system operation?

Upon VIN removal, it automatically transitions from charge mode to boost mode within <100µs, sourcing power from BATT to PMID and SYS. The IN→SYS pass-through path disables, and Q2 turns on to route battery power to SYS-ensuring zero-interruption operation for connected loads.

Is the 12µA standby current measured with ADC enabled or disabled?

The 12µA quiescent current is measured with ADC disabled, SYS plug-in detection disabled, and boost/suspend modes inactive. Enabling ADC increases current to ~2mA; enabling SYS plug-in detection adds ~1µA. All low-power states are I²C-configurable.

What package variants are available besides QFN-18?

MP2770GL-0000-P is exclusively offered in the QFN-18 (3mm×4mm) package. MPS does not offer SOIC, TSSOP, or WLCSP variants for this part number. The thermal pad and pinout are optimized for compact, high-density portable designs.
