Product Overview

Return to TOP

CXEP33121 is a dual-channel PMU: It integrates independent 7v withstand voltage linear charger and 28v asynchronous boost converter. The linear charger has a full-function constant current/constant voltage charging module, charging power tube and very few peripherals. It also contains trickle charging and full-speed charging current which can be set by external resistor. When constant voltage charging is entered and the charging current is less than 1/10 of the preset value, the charging is completed. CHRG and DONE are used to indicate the charging status. Its low-power 5v boost converter can support up to 5V-2A output capability, and can completely shut down the output by setting the ENBST pin low.
