描述 Description

 
ET9632 integrated OVP switch1 and load switch2.
The OVP switch1 can disconnect the systems from its output pin (VOUT) in case wrong input operating
conditions are detected. The system is positive overvoltage protected up to 24V.
The load switch2 can disconnect the systems from its output pin(SYS) in case wrong input operating
conditions are detected, the system is positive overvoltage protected up to 24V. And this switch has Reverse Current Blocking(RCB) function blocking unwanted reverse current from SYS to VBUS.
