Product details
Overview
MP2790DFP-0000-T from Monolithic Power Systems is a 4- to 10-cell battery monitor and protector IC with dual ADC architecture, ±2% SOC error (with MPF4279x fuel gauge), <5mV cell voltage measurement error, and integrated high-side CHG/DSG MOSFET drivers for e-bike and power tool BMS applications.
For engineers reviewing the MP2790DFP-0000-T datasheet, MP2790DFP-0000-T pinout, MP2790DFP-0000-T application, or MP2790DFP-0000-T equivalent, this page delivers verified cell balancing current (58mA), hardware-configurable protection thresholds (OV/UV/OT/SC), synchronous voltage–current sampling for impedance sensing, and TQFP-48 package thermal metrics (RθJA = 46.6°C/W).
Technical Context
The MP2790 integrates two independent sigma-delta ADCs: one for 10-channel differential cell voltage, die temperature, and four NTC inputs; another for high-accuracy current sensing via external shunt. This enables strictly synchronized V/I sampling at 2ms conversion time per channel-critical for real-time cell impedance monitoring and coulomb counting.
Its high-side N-channel MOSFET drivers support independent charge/discharge control with configurable soft-start on DSG, eliminating pre-charge circuits. Protection logic includes programmable thresholds for cell/pack OV/UV, OT/UT, DOC/COC, and SC-with dedicated hardware comparators and recovery options.

Equivalent & Alternatives
The following parts are listed as comparable options for similar battery monitor and protector applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BQ76952 | 16-bit SAR ADC (vs. MP2790's sigma-delta); no integrated CHG/DSG drivers; requires external FET controllers. | Targets lower-cost, lower-power BMS where external driver flexibility is preferred over integrated MOSFET control. | Select BQ76952 if system uses discrete gate drivers and prioritizes lower quiescent current (1.5µA shutdown vs. MP2790's 2µA). |
| ISL94203 | Supports up to 13 cells; single ADC architecture; no hardware-configurable SC/OC thresholds-relies on host MCU polling. | Suitable for cost-sensitive industrial UPS where software-managed protection suffices and cell count exceeds 10. | Choose ISL94203 only when >10-cell support is mandatory and synchronous V/I sampling is not required for impedance analysis. |
Compared with BQ76952 and ISL94203, the MP2790DFP-0000-T uniquely integrates dual sigma-delta ADCs with hardware-protection logic and high-side drivers-reducing BOM count by eliminating external gate drivers, pre-charge circuits, and discrete regulators while enabling sub-2% SOC accuracy.

FAQ
What communication protocols does MP2790DFP-0000-T support?
The MP2790DFP-0000-T supports both I²C and SPI interfaces with 8-bit CRC error checking. Pin configuration (SCL/SCK, SDA/SDI, SDO, GPIO3/nCS) determines protocol selection at power-up; default configuration for this part number is I²C.
Does MP2790DFP-0000-T include internal balancing MOSFETs?
Yes-it integrates on-die passive balancing MOSFETs rated for up to 58mA per cell at 25°C (15Ω–50Ω RDS(ON) over temperature). It also provides dedicated control signals to drive external balancing transistors for higher current or active balancing.
How does the MP2790 handle short-circuit detection?
It features hardware-accelerated short-circuit detection with configurable deglitch timing, achieving as fast as 120µs response latency. Detection uses the current-sense ADC with dual FSR ranges (1×/3×) and independent thresholds for charge and discharge paths.
What is the maximum supported battery stack voltage?
The MP2790 supports up to 47V on the TOP pin (10S Li-ion at 4.7V/cell), with absolute maximum ratings exceeding 80V on specific pins (e.g., CHG, DSG, CP). The device is rated for 4S–10S configurations with guaranteed performance across the full 10V–47V operating range.
Can MP2790DFP-0000-T operate without an external microcontroller?
No-it requires a host MCU for register configuration, status polling, and command execution. However, all critical protections (OV/UV/OT/SC/OC) execute autonomously in hardware, maintaining safety even during host communication loss or reset.
What thermal management features are built into the MP2790?
It includes die temperature monitoring with hardware over-temperature shutdown at 140°C–155°C, plus thermal resistance metrics (RθJA = 46.6°C/W) validated per JEDEC standards. The TQFP-48 package features an exposed thermal pad for direct PCB copper thermal coupling.
Is there an evaluation kit available for MP2790DFP-0000-T?
Yes-the EVKT-MP2790-0000 kit includes the EV2790-0000-FP-00B I²C evaluation board, USB-to-I²C interface, cables, and GUI software. It supports full register access, real-time telemetry, and protection event triggering for rapid BMS development.
