About This Product

■Summary

The MP2796 is a rugged battery management device that provides a complete analog front end (AFE) monitoring and protection solution. It is designed for multi-cell series battery management systems (BMS). The device can support serial interface or SPI communication. The MP2797 supports series connection of 7-cell to 16-cell battery packs with absolute voltages greater than 80V on certain pins. The MP2796 integrates two independent analog-to-digital converters (ADCs). The first ADC measures the differential cell voltage of each channel (up to 16 channels), die temperature, and temperature of four channels through external NTC thermistors. The second ADC measures the charging and discharging current through an external current sensing resistor. When combined with the MPF4279x battery fuel gauge, the MP2796 achieves a state of charge (SOC) error within 2%. The MP2796 includes a high-side MOSFET (HS-FET) driver for charge/discharge control. The discharge (DSG) MOSFET driver includes a programmable soft-start (SS) to provide controlled turn-on, eliminating the need for external precharge circuitry. The MOSFET driver also incorporates overcurrent protection (OCP), short circuit protection (SCP), battery undervoltage protection (UVP), battery overvoltage protection (OVP), and high/low temperature protection. All protections have configurable thresholds. Internal passive balancing MOSFETs can be used to equalize mismatched cells and support up to 58mA. There is also an option to drive external balancing transistors (MOSFETs or BJTs). The MP2796 is available in a TQFP-48 (7mm x 7mm) package.

■Built-in dual analog-to-digital converter (ADC) architecture

・State of Charge (SOC) error of less than ±2% due to MPF4279x fuel gauge ・Cell voltage measurement error less than 10mV ・Current error <±0.5%
