The SY86809A/SY86809D is a programmable current limit switch with input voltage range selection and output voltage clamping. Extremely low RDS(ON) of the integrated protection Nchannel FET helps to reduce power loss during the normal operation. Programmable soft-start time controls the slew rate of the output voltage during the start-up time. Independent enable control allows the complicated system sequencing control. It integrates the over-temperature protection shutdown and auto-recovery with hysteresis. This IC along with small QFN2×2.5-10 footprint provides small PCB area application.
