ETA6915
Description
Features
ETA6915 is a PMU, which integrates a 28V single cell Li+ battery Switching charger, and a 5V/1A Boost synchronous converter with true-shutoff function.
ETA6915 has two versions: non-I2C and I2C serial interface versions. For the Switching Charger Module, the pre-charge current, constant current (CC) and the terminal Charge Current can be programmed through the I2C serial interface and the charging status can be read from the register.
For the Boost synchronous converter module, the output voltage can be programmed through the I2C serial interface.
ETA6915 also has NTC Protection for battery safety, which is effective during charge and discharge mode. ETA6915 is available in a QFN3x3-16L package (I2C version) and DFN3x3-10 package (non-I2C version).
