General Description

The SY20819E is an 18V, 5A protection switch

with output voltage clamping. Extremely low

RDS(ON) of the integrated protection N-channel

MOSFETs helps to reduce the power loss during

normal operation. The programmable soft-start

time controls the slew rate of the output voltage

during the start-up time.

The SY20819E can withstand a negative input

voltage as low as -6V, protecting the load from

being damaged by negative voltages.

Over-current and thermal limit protections are

provided to enable reliable operation of the

system.

The SY20819E is available in a compact QFN

2mm×2mm-9pin package.
