General Description
The ET9531 is a OVP switch can disconnect the systems from its output pin (OUT) in case wrong input operating conditions are detected. The system is positive over-voltage protected up to 28V.
When input (OVLO) is set lower than 0.2V, the over-voltage protection threshold is 5.9V. The over-voltage protection threshold can also be adjusted by external resistors when input (OVLO) is set higher than 0.3V.
The ET9531 provide over temperature protection and also provide reverse current blocking when the ET9531’s switch is disabled.
The ET9531 provide OTG function allows OUT voltage to supply IN.
