DESCRIPTION
The TPS2345 CompactPCIR Hot Swap Power
Manager
(HSPM)
provides
highly-integrated
supply control of three positive (3.3-V, 5-V, and
12-V) and one negative (–12-V) supply rails with
a minimum number of external components. A
linear current amplifier (LCA) in each of the four
device channels provides closed-loop control of
load current during insertion and extraction
events. This allows the designer to configure the
plug-in card’s maximum inrush slew rate and
magnitude according to the requirements of the
