DESCRIPTION

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
