CJC5248 is a DC-DC power management IC, which perfectly solves the transient power failure of the power supply and causes the system
Reset and other problems. This chip integrates power detection module, boost control management module, LDO module
Stream protection module. This chip solves the problem that when the power module outputs large current in a transient state, the power supply to the main control IC is not
Stable, causing problems such as reset of the master IC. It completely replaces the complex scheme of boosting IC+LDO in the current market.
Highly integrated, few peripheral components
Support input voltage 2.2V~5.2V
Support VCC transient power down to 1.5V, and output 3.3V stably at OUT terminal
Boost output circuit efficiency: above 90%
Sleep power consumption: 600uA
Maximum 400mA output
Chip undervoltage protection
Chip over-current and short circuit protection
Chip over temperature protection
5-pin SOT-23 package
