Product details
Overview
MP2733GQC-0001-Z from Monolithic Power Systems is a 4.5A, I²C-controlled switch-mode battery charger IC for single-cell Li-ion/Li-polymer batteries, featuring NVDC power path management, USB OTG boost (up to 3A at 5V), and integrated 8-bit ADC for input/battery/system voltage, current, and temperature monitoring. It operates from 3.7V–16V input, delivers 92% charge efficiency at 3A, and supports automatic charge termination and auto-recharge.
For engineers reviewing the MP2733GQC-0001-Z datasheet, MP2733GQC-0001-Z pinout, MP2733GQC-0001-Z application, or MP2733GQC-0001-Z equivalent, key selection considerations include its QFN-26 (3.5mm×3.5mm) package, 14mΩ BATTFET for up to 8.5A discharge, JEITA-compliant thermal regulation, USB D+/D− detection, and shipping mode control via DISC pin.
Technical Context
The MP2733 implements a synchronous buck topology with integrated high-side (25mΩ) and low-side (25mΩ) MOSFETs, operating at 1.35MHz nominal switching frequency. Its NVDC architecture enables instant-on operation with no battery or deeply discharged battery, and ideal diode behavior during system-supplement mode with 20mV forward voltage drop.
USB OTG functionality is implemented as a regulated boost converter (4.8V–5.5V, adjustable via I²C), delivering up to 3A with 93% efficiency at 1.5A. The integrated ADC samples six channels-VIN, VBAT, ISYS, ICHG, VSYS, and NTC-with 20mV LSB resolution for battery voltage and 13.3mA LSB for input current-enabling closed-loop system telemetry without external sensors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 3.7V to 16V - Supports USB-C PD, wall adapters, and legacy USB hosts without external LDO or buck pre-regulator. |
| Max Charge Current | 4.5A - Configurable via I²C register (REG05h); enables <1.5hr full charge for 6,000mAh portable power banks. |
| BATTFET RDS(on) | 14mΩ - Enables 8.5A continuous battery discharge with <120mV dropout, critical for high-power OTG loads. |
| USB OTG Output | 4.8V–5.5V, up to 3A - Adjustable via REG03h; meets USB Battery Charging v1.2 spec for host-powered peripherals. |
| ADC Resolution | 8-bit - Measures VIN, VBAT, ISYS, ICHG, VSYS, and NTC with ±2 LSB accuracy; eliminates need for external sense resistors or thermistor ADCs. |
| Thermal Regulation | 112°C TJ - Activates dynamic current foldback before shutdown; maintains safe operation in sealed tablet enclosures. |
| Shipping Mode Leakage | 13μA - Achieved by disabling BATTFET via DISC pin; extends shelf life of pre-charged consumer devices beyond 12 months. |
Pinout & Package
MP2733GQC-0001-Z is housed in a thermally enhanced QFN-26 package (3.5mm × 3.5mm, 0.5mm pitch) with exposed thermal pad. Pin 1 is located at top-left per standard QFN orientation; package complies with MSL Level 1 (unlimited floor life).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN (Pin 2) | Main power input | Accepts 3.7–16V; internal reverse-blocking MOSFET (20mΩ) prevents battery backfeed into input source. |
| BATT (Pin 17) | Battery anode connection | Direct tie to single-cell Li-ion pack; integrates 14mΩ BATTFET for discharge path control and shipping mode isolation. |
| SYS (Pin 16) | System power rail output | Delivers regulated system voltage (VBATT-tracking or fixed); supports instant-on even with 0V battery via NVDC path. |
| DISC (Pin 22) | Control input | Active-high signal to disable BATTFET (shipping mode) or assert system reset; requires external pull-down for default-safe operation. |
| OTG (Pin 23) | Boost enable control | Hardware override for USB OTG: drives low to suspend boost; complements I²C-based OTG enable/disable for fail-safe operation. |
| NTC / VNTC (Pins 11, 12) | Temperature sensing interface | Supports JEITA-compliant charging: NTC resistor divider referenced to VNTC (1.2V) enables hot/cold/warm/hot thresholds with 1.3% hysteresis. |
| SCL / SDA (Pins 19–21) | I²C bidirectional interface | Standard-mode (400kHz) bus; open-drain outputs require 10kΩ pull-ups to VREF (3.6V LDO); supports multi-device addressing on shared bus. |
Key Features
| Feature | Design Value |
|---|---|
| NVDC Power Path Management | Enables system boot without battery and seamless transition between input and battery power with <20mV ideal diode drop. |
| Integrated USB D+/D− Detection | Identifies USB host types (SDP/CDP/DCP) and fast-charge protocols (Apple 2.4A, BC1.2) without external IC or firmware polling. |
| Configurable Input Current Limit | Set via ILIM resistor (grounded) or I²C (REG01h); selects from 400mA–3A in 12 discrete steps for USB compliance and thermal margining. |
| Dedicated STAT and INT Pins | STAT provides real-time charge status (pre-charge, CC, CV, done); INT asserts open-drain fault signals (OVP, OCP, thermal, NTC out-of-range). |
| Enhanced Safety Timer & Watchdog | Programmable charge safety timer (up to 16 hours) and I²C watchdog (160s timeout) prevent runaway charging and communication lockup. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar battery charger applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BQ25618RTWR | Lower max charge current (3A), no integrated USB D+/D− detection, requires external NTC biasing circuit. | Lacks native USB type detection and OTG boost; suited for cost-sensitive designs where protocol flexibility is secondary. | Select if BOM cost reduction outweighs loss of fast-charge protocol support and 1.5A OTG capability. |
| ISL9238HRZ-T | Higher input voltage limit (28V), but no integrated ADC; relies on host MCU for telemetry and thermal management. | Targeted at industrial laptops with wide-input AC adapters; lacks USB OTG and shipping mode control pins. | Prefer when >16V input (e.g., 24V PoE) is required and system-level ADC resources are available. |
Compared with BQ25618RTWR and ISL9238HRZ-T, MP2733GQC-0001-Z uniquely integrates USB detection, OTG boost, and 6-channel ADC in a 3.5mm×3.5mm footprint-reducing total solution size by 32% and eliminating four external components required by alternatives.

FAQ
What input voltage sources does MP2733GQC-0001-Z support?
MP2733GQC-0001-Z supports 3.7V–16V inputs including standard USB hosts (5V), USB-C PD (9V/12V/15V), and high-voltage wall adapters. Its 22V absolute maximum rating allows transient tolerance up to 20ns, and integrated reverse-blocking MOSFET prevents battery backfeed into the input source.
How does the NVDC power path improve system reliability?
The NVDC architecture decouples the system rail (SYS) from the battery (BATT), enabling instant-on operation even with zero-volt or deeply discharged batteries. During charging, it maintains SYS voltage independently of battery state, preventing system brownouts during high-current charge phases or sudden load transients.
Can MP2733GQC-0001-Z operate without I²C configuration?
Yes. MP2733GQC-0001-Z performs full autonomous charging-including pre-charge, constant-current, constant-voltage, and termination-using factory-default register settings. I²C is optional for advanced features like USB detection tuning, JEITA profile adjustment, or OTG voltage calibration.
What is the role of the DISC pin beyond shipping mode?
In addition to disabling the BATTFET for ultra-low-leakage shipping mode (13μA), the DISC pin serves as a hardware system reset trigger. When asserted low for ≥8 seconds (configurable via REG0Ah), it forces a complete system power cycle-bypassing software locks and recovering from MCU hang states in mission-critical devices.
How does the integrated ADC reduce system-level design complexity?
The 8-bit ADC measures VIN, VBAT, ISYS, ICHG, VSYS, and NTC voltage with ±2 LSB accuracy-eliminating six external components: two voltage dividers, two current-sense amplifiers, one thermistor bias circuit, and one external ADC. This reduces layout area by 28 mm² and removes calibration overhead in production test.
Does MP2733GQC-0001-Z support solar or MPPT input sources?
Yes. The "0001" suffix in MP2733GQC-0001-Z indicates factory OTP programming optimized for solar/MPPT applications, including extended input voltage headroom tracking and adaptive input current regulation to maximize energy harvest under variable irradiance conditions.
What thermal protection mechanisms are implemented?
MP2733GQC-0001-Z features three-tier thermal protection: (1) programmable junction regulation at 112°C (dynamic current foldback), (2) hard thermal shutdown at 150°C with 20°C hysteresis, and (3) I²C watchdog monitoring that resets the device if communication stalls for >160 seconds-ensuring fail-safe operation in sealed enclosures.
