SY6882A/B integrates an extremely low RDS(ON) N-channel MOSFET with precise over-voltage protection to against high-voltage faults up to 25V. Linear mode is active to maintain the output voltage at 5.5V with the input voltage up to the input over-voltage threshold. SY6882A is available with internal fixed over-voltage protection point at 7.1V and SY6882B has the programmable over-voltage threshold by two external resistors. The internal NFET will be turned off to disconnect input and output when the VIN is higher than the over-voltage threshold. Low RDS(ON) of the integrated switch helps to reduce power loss during the normal operation.Control the /EN pin to enable or disable the device and /FLB indicates OVP and OTP.
