SY76875

Programmable Current Limit Switch

General Description

SY76875 is a programmable current limit switch with input voltage range selection and output voltage clamping. Extremely low R DS(ON) of the integrated protection N-channel 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 hystersis. This IC along with small DFN3X3-10 footprint provides small PCB area application.
