Typical Application


SY6885B is a current limit switch with programmable input over voltage protection and output voltage clamping. Extremely low RDS(ON) of the integrated protection N-channel FET helps to reduce power loss during normal operation. Programmable soft-start time controls the slew rate of the output voltage during start-up. Independent enable control allows the complicated system sequencing control. The device also integrates thermal shutdown protection. This device along with small QFN3×3-16 footprint provides small PCB area application.
