Monolithic Power Systems (MPS) MP2787 Battery Monitors
Monolithic Power Systems (MPS) MP2787 Battery Monitors are designed for multiple-cell series Battery Management Systems (BMS) and can support I2C or SPI communication. These devices are robust battery management devices that provide complete Analog Front-End (AFE) monitoring. This device is available in a TQFP-48 (7mm x 7mm) package.
Features
- Incorporates 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%
- Strictly synchronized current/voltage measurement for impedance sensing
- Hardware configurable alarms:
- Charge/discharge Over-Current (OC) interrupt
- Cell Under-Voltage (UV) and OverVoltage (OV) interrupt
- Pack UV and OV interrupt
- Cell Low-/high-temperature interrupt
- Die high-temperature interrupt
- Passive cell balancing up to 58mA per cell:
- Can drive external balancing transistors
- Automatic or manual control
- Additional features:
- Integrated 3.3V and 5V Low-Dropout (LDO) regulators
- High-voltage and low-voltage GPIOs
- Dedicated thermistor inputs
- Open wire detection
- Persistent dead battery flag
- Lockable Multiple-Time Programmable (MTP) memory for key thresholds
- I2C or SPI interface with 8-bit Cyclic Redundancy Check (CRC)
- Random cell connection tolerant
- Available in a TQFP-48 (7mm x 7mm) package
Applications
- Power and gardening tools
- E-bikes and e-scooters
