PW1555 is a programmable 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 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
autorecovery with hystersis.
This IC along with small DFN3X3-10 footprint provides small PCB area application.
