Product details
Overview
MP2733GQC-0001-P 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), integrated 8-bit ADC, and JEITA-compliant temperature monitoring. It operates from 3.7V–16V input, delivers 92% charge efficiency at 3A, and supports instant-on operation with deeply discharged or absent batteries - deployed in smartphones, tablets, and wireless cameras.
For engineers reviewing the MP2733GQC-0001-P datasheet, MP2733GQC-0001-P pinout, MP2733GQC-0001-P application, or MP2733GQC-0001-P equivalent, key selection considerations include its QFN-26 (3.5mm×3.5mm) package, 14mΩ BATTFET, 1.35MHz buck switching frequency, I²C-configurable charge voltage (3.4V–4.67V), and dual-role USB DP/DM interface for fast-charge protocol detection and OTG control.
Technical Context
The MP2733 implements a synchronous buck topology with fully integrated high-side (25mΩ) and low-side (25mΩ) MOSFETs, reverse-blocking FET (20mΩ), and BATTFET (14mΩ), enabling efficient charging and system power path arbitration. Its NVDC architecture decouples battery and system rails, allowing SYS to remain powered during battery charging or absence.
USB OTG is implemented via an internal boost converter controlled by I²C registers and the OTG pin, delivering 4.8V–5.5V output with up to 3A current limit. The integrated 8-bit ADC monitors six analog signals - VIN, IIN, VBATT, ICHG, VSYS, and NTC voltage - with ±2 LSB accuracy and configurable sampling.

Pinout & Package
MP2733GQC-0001-P is housed in a thermally enhanced QFN-26 package (3.5mm × 3.5mm, 0.5mm pitch) with exposed thermal pad. Pin numbering follows standard top-view orientation per MPS datasheet Rev. 1.1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 26 (DP) | USB D+ data line | Configurable I/O for USB detection, fast-charge negotiation (BC1.2, DCP, CDP), and OTG host signaling. |
| 2 (IN) | Main power input | Accepts 3.7V–16V input; connects to 1µF ceramic bypass capacitor for noise suppression and transient response. |
| 3 (PMID) | Internal power rail | Drain node of reverse-blocking FET and HS-FET; requires 10µF local bypass to stabilize gate drive and reduce ripple. |
| 4 (SW) | Switching node | Connects to inductor and BST capacitor; critical for buck converter operation and EMI layout integrity. |
| 5–7 (PGND) | Power ground | Low-impedance return path for high-current switching loops; must be tied directly to thermal pad and external GND plane. |
| 8 (BST) | Bootstrap supply | Forms floating gate drive for HS-FET via 47nF capacitor to SW; enables 100% duty cycle capability. |
| 9 (STAT) | Open-drain status indicator | Signals charge state (trickle/pre-charge/CC/CV/complete/fault) with external 10kΩ pull-up to VREF. |
| 10 (INT) | Open-drain interrupt | Asserts on fault events (OVP, OCP, thermal shutdown, JEITA violation) for host processor notification. |
| 11 (NTC) | Temperature sense input | Analog input for NTC thermistor divider; used with VNTC to implement JEITA-compliant hot/cold/warm thresholds. |
| 12 (VNTC) | NTC bias reference | Provides stable 1.2V reference (derived from VREF) for NTC comparator; sets temperature window boundaries. |
| 13–14 (VREF) | Internal LDO output | 3.6V, 40mA LDO powering internal circuitry and external bias networks; requires 10µF ceramic decoupling. |
| 15 (AGND) | Analog ground | Separate ground for ADC, comparators, and reference circuits; must be star-connected to PGND at single point. |
| 16 (SYS) | System power output | Regulated system rail (VBATT-tracking or fixed); supplies SoC, display, and peripherals with ideal diode support. |
| 17 (BATT) | Battery positive terminal | Direct connection to single-cell Li-ion pack; bypassed with 22µF ceramic capacitor for low-ESR filtering. |
| 18 (CE) | Charge enable (active-low) | Hardware override for I²C-controlled charge enable/disable; low = charge enabled if register permits. |
| 19–20 (SCL) | I²C clock input | Standard-mode (100kHz) or fast-mode (400kHz) clock; requires 10kΩ pull-up to logic rail (1.8V/3.3V). |
| 21 (SDA) | I²C bidirectional data | Open-drain I/O; shares same 10kΩ pull-up as SCL; supports read/write of 48 registers including OTP map. |
| 22 (DISC) | Disconnection control | Enables shipping mode (BATTFET off, 13µA leakage) and system reset; debounced via I²C register REG0Ah. |
| 23 (OTG) | OTG boost enable | Hardware suspend control for boost mode; low = disables OTG output while preserving I²C configuration. |
| 24 (ILIM) | Input current limit set | Analog pin setting max input current (400mA–3A) via resistor-to-ground; overrides I²C value if lower. |
| 25 (DM) | USB D− data line | Complementary to DP; enables USB enumeration, BC1.2 detection, and OTG host negotiation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar switch-mode battery charger applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BQ25618RTWR (TI) | 3A max charge current; 1.2MHz switching; no integrated USB DP/DM detection; separate NTC bias required. | Lacks native USB type detection and fast-charge negotiation - requires external BC1.2 IC or MCU firmware handling. | Select when lower cost and simpler USB integration are prioritized over 4.5A capacity and autonomous protocol detection. |

FAQ
What input voltage range does MP2733GQC-0001-P support, and how does it handle overvoltage?
MP2733GQC-0001-P supports 3.7V to 16V input with sustained 22V absolute maximum rating. Input overvoltage protection triggers at 5.8V–6.3V (for 5V sources) or 16.2V–17.2V (for >5V sources), with 380mV hysteresis. This dual-threshold OVP prevents damage from transient surges or misconnected adapters while maintaining compatibility with USB PD and high-voltage wall chargers.
How does the NVDC power path enable instant-on functionality with a dead battery?
NVDC separates the system (SYS) rail from the battery (BATT) rail using internal ideal diode control. When the battery is absent or deeply discharged (<2.6V), SYS is powered directly from IN via the BATTFET in supplement mode, enabling immediate system boot. The 20mV forward voltage drop and automatic entry/exit hysteresis ensure seamless transitions without brownouts.
Can MP2733GQC-0001-P operate in shipping mode, and what is the battery leakage current?
Yes - asserting the DISC pin low (or configuring REG0Ah) disables the BATTFET and places the IC in shipping mode, reducing battery leakage to 13µA typical at 4.2V. This is achieved via internal bias shutdown and gate isolation, extending shelf life beyond 12 months without requiring external switches or PCB modifications.
What level of USB fast-charge protocol support does MP2733GQC-0001-P provide natively?
MP2733GQC-0001-P natively detects USB BC1.2 SDP/CDP/DCP and supports proprietary fast-charge negotiation via configurable D+/D− voltage thresholds (1.7V, 2.2V, 2.4V, 2.9V). It does not implement QC/AFC/PD PHY layers but provides the analog foundation for MCU-based protocol handshaking - eliminating need for discrete BC1.2 ICs.
How accurate is the integrated ADC, and which parameters does it measure?
The 8-bit ADC measures six parameters: VIN (±2 LSB, 60mV LSB), VBATT (±2 LSB, 20mV LSB), ICHG (±3 LSB, 17.5mA LSB), VSYS (±2 LSB, 20mV LSB), IIN (±4 LSB, 13.3mA LSB), and VNTC (±2 LSB, 0.392% LSB). All conversions occur internally without host polling overhead, enabling real-time telemetry for battery health algorithms.
Does MP2733GQC-0001-P require external MOSFETs, and what is its thermal performance?
No external MOSFETs are required - MP2733GQC-0001-P integrates all power switches: 20mΩ reverse-blocking FET, 25mΩ HS-FET, 25mΩ LS-FET, and 14mΩ BATTFET. With θJA = 48°C/W on a 4-layer board, it sustains 4.5A charging at TA = 25°C without thermal derating; junction temperature remains below 112°C under full load before regulation engages.
What safety protections are implemented, and how are faults reported?
Protections include input/system OVP, battery OVP (103.5% of VBATT_REG), thermal regulation (112°C) and shutdown (150°C), JEITA temperature windows, charging safety timer, and watchdog-monitored I²C. Faults assert the open-drain INT pin, and status is readable via I²C register REG0Bh - enabling host-driven recovery without hard reset.
