ETA9897
Ultra-Low Power PMU with 30V Linear Charger and 5V Boost Converter
DESCRIPTION
ETA9897 is an ultra-low power PMU with 2 modules: a 30V single cell Li+ battery linear charger and a 5V boost synchronous converter with true-shutoff function. The linear charger fully integrated constant current (CC) / constant voltage (CV) control module and charge FET, with minimal external devices. It also has pre-charge function for trickle charging deeply discharged battery and its fast charge current can be programmed by an external resistor. When CV charge stage is entered, charge will be terminated once the charge current drops to 1/10 of the programmed value. A “STAT” pin is also available to indicate the charge status. And the low power 5V boost converter is capable of delivering 0.
