MP2791DFP Integrated Circuit Chip High-Accuracy Battery Controller with Coulomb Counting for 7-14 Cell Systems and Dual ADC Architecture

Description

Part Number:

MP2791DFP

Package:

TQFP-48

Number Of Cells:

7 ~ 14

Operating Temperature:

-40°C ~ 85°C (TJ)

Highlight:

High-Accuracy Coulomb Counting Battery Controller

7-14 Cell Support Integrated Circuit Chip

Dual ADC Architecture AFE Monitoring Device

MP2791DFP Integrated Circuit Chip High-Accuracy Multi-Function Battery Controller With Coulomb Counting

The MP2791DFP is a robust battery management device that provides a complete analog front-end (AFE) monitoring and protection solution. Designed for multiple-cell series battery management systems (BMS), this device supports I2C or SPI communication and accommodates 7-cell to 14-cell series battery packs, with an absolute voltage exceeding 75V on particular pins.

MP2791DFP integrates two separate analog-to-digital converters (ADCs). The first ADC measures each channel's differential cell voltages (up to 14 channels), die temperature, and 4-channel temperatures via external negative temperature coefficient (NTC) thermistors. The second ADC measures the charge/discharge current via an external current-sense resistor. The dual ADC architecture enables synchronous voltage and current measurements for cell and pack impedance monitoring.

Key Features & Benefits

Dual Analog-to-Digital Converter (ADC) Architecture
<±2% State-of-Charge (SOC) Error with MPF4279x Fuel Gauge
Cell Voltage Measurement Error <5mV
Current/Coulomb Counter Error <±0.5%

N-Channel High-Side MOSFET (HS-FET) Drivers for Charge and Discharge Control
Supports MOSFET Soft-Start (SS) Discharge Control to Eliminate Pre-Charge Circuit
Drives Up to 100A DC with Parallel N-Channel MOSFETs
Hardware Configurable Protections including OCP, SCP, UVP, OVP, and Temperature Protection
Passive Cell-Balancing Up to 58mA per Cell
Integrated 3.3V and 5V Low-Dropout (LDO) Regulators
Reduced Current Standby Mode
Load and Charger Plug-In Detection
I2C or SPI Interface with 8-Bit Cyclical Redundancy Check (CRC)
Available in TQFP-48 (7mmx7mm) Package

Applications

Battery Backups and UPSs, E-Bikes, E-Scooters, Light Electric Vehicles (LEVs), Energy Storage Systems (ESS), Power and Gardening Tools
