1-A Li-ion and LiFePO4 I²C programmable linear charger with regulated power path, WCSP package

BQ25180YBGR General Description

To enhance user experience and reduce overall system footprint, the BQ25180YBGR integrates a single push-button input and reset circuitry. This simplifies the user interface and reduces the need for additional components, making it an ideal choice for space-constrained applications

Got the goods, threw it in my mailbox. The delivery was not quite fast, but nevertheless it did not cause discontent. Packed was good, the quantity exceeded by 11 pieces. In the work did not test, but i think everything will be fine.
