Monolithic Power System (MPS) MP2651 Buck-Boost Charger ic is designed for battery packs of one to four cells in series. The MP2651 offers a wide input voltage (VIN) range of 4V to 22V to charge the battery. The device's step-boost topology authorized battery voltage is higher or lower than VIN. The MPS MP2651 Buck-Boost Charger ic operates in charge mode when input is present.
The device can measure the battery voltage and charge the battery in four stages. The four stages are constant trickle charging, constant pre-charging, constant fast charging and constant voltage charging. Other features include charge termination and automatic charging. Integrated input current (IIN) and VIN limits to avoid input power overload.
The MP2651 can also provide a wide voltage range (3V to 21V) at the input when power mode is convenient. The device also has high resolution output current (IOUT) limits in source mode. The MP2651 charger ic comes in a TQFN-30 (4mm x 5mm) package.
