DESCRIPTION
When input (OVLO) is set lower than 0.2V. The overvoltage protection threshold is 5.9V. The overvoltage protection threshold can also be adjusted by external resistors when input (OVLO) is set higher than 0.3V. The WP3891 provide Over Temperature Protection and also provide Reverse Current Blocking when the WP3891’s switch is disabled. The WP3891 provide OTG function allows OUT voltage to supply IN. The device is packaged in advanced Full-Green compliant 2.1mmx1.6mm Wafer Level Chip Scale Packaging (WLCSP). FEATURES
