MP2672AGD-0000-P

MP2672A is a highly integrated, flexible switch mode battery charger IC for lithium-ion batteries with two cells in series. This makes it applicable for a wide range of portable applications. When an input power supply is present, the MP2672A operates in boost mode to charge battery with two cells in series. When charging is enabled, the MP2672A automatically detects battery voltage and charges battery in three phases: pre-charge, constant current charge and constant voltage charge. Other features include charge termination and auto-recharge. It can monitor voltage across each cell, then equalize the cell’s voltages if the difference between the two cells exceeds the mismatch threshold. The device has two configuration modes: standalone mode and host-control mode. safety features include input over-voltage protection, battery OVP, thermal shutdown, battery temperature monitoring, a watchdog timer and a configurable backup timer to prevent prolonged charging of a dead battery.

• 4V to 5.75V operating voltage, up to 14V sustainable voltage, narrow voltage DC power structure
• Up to 2A configurable charge current for battery with 2 cells in series, cell balance function
• Configurable input voltage limit, configurable charge voltage with 0.5% accuracy
• No external sense resistor required, integrated cell balancing circuit for mismatched cells
• Charging operation indicator in standalone mode, missing battery detection in host control mode
• I2C port for flexible system parameter, setting and status reporting in host control mode
• Negative temperature coefficient pin for temperature monitoring compliant with JEITA standards
• Highly integrated without sense resistor, cost effective solution
• One time programmable (OTP) memory, I2C programmable charging parameters
• MOSFET cycle-by-cycle overcurrent protection (OCP)
