It targets portable consumer and industrial equipment where the host microcontroller manages the charging profile rather than relying on fixed resistor straps. The device charges a single cell (Number of Cells: 1) with a maximum charge current of 1.5A and supports a battery pack voltage up to 4.44V. The supply voltage range goes up to 9V, which covers standard 5V USB or 5V wall-adapter inputs with margin for cable drops. Fault protection includes over-temperature and over-voltage shutdown.
Design-in: supply rail and thermal budget
The 9V maximum supply (Voltage - Supply (Max): 9V) means this part works from a standard 5V USB VBUS or a 5V regulated rail, but a 12V input requires a pre-regulator. At 1.5A charge current the DSBGA package (30-DSBGA) relies on the PCB copper for heat spreading — the datasheet layout recommendation for the thermal vias under the package should be followed closely to keep junction temperature within limits. The I²C interface (Interface: I²C) allows the host to set the charge current and timer values on the fly, which is useful for charging different battery capacities in the same hardware design or for implementing a safety timeout. No external programming resistors are needed.
The part is sourced to order against an RFQ — no stock or price figures are published here, but a quote request will return real-time supply position.
