The SY28815B is a current limit switch with input voltage range selection and output voltage clamping. Extremely low RDS(ON) of the integrated protection N-channel FET helps to reduce the power loss during the 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. It integrates the over-temperature protection shutdown and the auto-recovery with hysteresis. This IC along with small DFN3×3-10 footprint provides small PCB area application.
