ETA9697二合一藍(lán)牙充電倉(cāng)充放電芯片

ETA9897 isan ultra-low power PMU with 2 modules: a 30V single cell Li+battery linear charger and a 5V boost synchronous converter withtrue-shutoff function. The linear charger fully integrated constantcurrent (CC) / constant voltage (CV) control module and charge FET,with minimal external devices. It also has pre-charge function fortrickle charging deeply discharged battery and its fast chargecurrent can be programmed by an external resistor. When CV chargestage is entered, charge will be terminated once the charge currentdrops to 1/10 of the programmed value. A “STAT” pin is alsoavailable to indicate the charge status. And the low power 5V boostconverter is capable of delivering 0.4A current at 5V output. Itcan be shut down by pulling ENBST low, it will disconnect theoutput from the BAT to further decrease the system standby power.Its 1.4MHz switching frequency enable a very small externalinductor with inductance as low as 2.2uH. The ETA9897, as a whole,is an ideal for the system solution that requires very low standbypower and compact PCB board size.

ETA9897 is housed in a ESOP8 package.
