• Manufacturer Part Number: MIC2583
• Description: Single Channel Hot Swap Controllers
• Manufacturer: Micrel Semiconductor

Power MOSFET, timer(s), and feedback network connec-
tions. The feedback network resistor values are selected for
a 12V application. Many hot swap applications will require
load currents of several amperes. Therefore, the power (V
and Return) trace widths (W) need to be wide enough to allow
the current to flow while the rise in temperature for a given
copper plate (e.g., 1oz. or 2oz.) is kept to a maximum of
10 C~25 C. Also, these traces should be as short as possible
in order to minimize the IR drops between the input and the
load. For a starting point, there are many trace width calcu-
lation tools available on the web such as the following link:

* These devices are not limited to these conditions in many cases, but these conditions are provided as a helpful reference for customer applications.

Finally, the use of plated-through vias will be needed to make
circuit connections to power and ground planes when utilizing
multi-layer PC boards.
MOSFET and Sense Resistor Vendors
Device types and manufacturer contact information for power
MOSFETs and sense resistors is provided in Table 4. Some
of the recommended MOSFETs include a metal heat sink on
the bottom side of the package. The recommended trace for
the MOSFET Gate of Figure 11 must be redirected when
using MOSFETs packaged in this style. Contact the device
manufacturer for package information.
