Typical Application

Description

SY6883 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. SY6883 has programmable over-voltage threshold using two external resistors. The internal NFET is turned off to disconnect input and output when 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.
