Texas Instruments BQ24780SRUYT

BQ24780SRUYT Description The BQ24780SRUYT is a high-efficiency, synchronous battery charger with a low component count for multi-chemistry battery charging applications that are space-constrained. The hybrid power boost mode is supported by the BQ24780SRUYT (previously called "turbo boost mode"). When the system's power demand is temporarily higher than the adapter's maximum power level, it allows the battery to discharge energy to the system. As a result, the adapter does not crash. For autonomous system power source selection, the BQ24780SRUYT uses two charge pumps to operate N-channel MOSFETs (ACFET, RBFET, and BATFET) individually.
Texas Instruments is a brand that offers a PMIC - Battery Chargers chip, specifically belonging to the PMIC - Battery Chargers category. The chip is surface mountable with a total of 28 pins and terminations. It is classified under the JESD-609 Code e4 and has an ECCN Code of EAR99. The terminal form does not include any leads, and it has a pin count of 28. The chip operates with a single channel and has a thickness of 750μm. Moreover, it complies with the ROHS3 standards.
