Functional description
Figure 1
shows the block diagram of the PIP401, which contains the following
functional blocks:
High-speed comparator with remote sense input
Power switch driver stage
Series power switch with very low on-state resistance
Overtemperature detection circuit with open collector output.
Figure 2
shows the basic application circuit for the PIP401. The protected supply is
connected to VI. The output (VO) is connected to the system bus. An auxiliary supply
biases V
CC
. The remote sense input (VRS) is joined to VO at the load point.
