The SY20845A 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 MOSFET helps to reduce power loss during normal operation. The programmable soft-start time controls the slew rate of the output voltage during the start-up time.
The SY20845A uses an enable control for system sequencing. The programmable current limit can be configured using an external resistor. The device integrates short-circuit and overtemperature protections.
The SY20845A is available in a compact DFN 3mmx3mm-10pin package.
