Overview
This document assumes the reader is familiar with the hot
plug concept, and has a copy of the ISL6140/50, and
ISL6141/51datasheets referenced on the first page.
The ISL6140/41EVAL1 Board Set is made up of 3 boards
(see Figures 1, 2, and 5 for various representations):
• BUS board: Input -48V power bus
• CONTROL board: IC hot-plug functions
• LOAD board: Load resistors and capacitors
The 3 board set allows the user to simulate plugging a board
into a live edge connector OR simulate plugging a live load
into a motherboard.
• Most component values have been optimized for

changed at either voltage extreme for optimal (or even
acceptable) performance. For example, LED brightness is
determined by the supply voltage through a current
limiting resistor; the brightness at -10V is low, and high at -
80V. If the board is to be used at a single fixed voltage
level, some components might be changed to
accommodate.
share one power supply (connect -VINA and -VINB
together, either on the board, or externally), or they can
each have their own supply (even at different voltages);
there is no interaction between them (other than sharing
the common GND). No special power up or down
sequencing is required. The default board is shipped with
an ISL6140 in Channel A, and an ISL6141 in Channel B.
See Figure 7 for schematic. ISL6150 and ISL6151 devices
are also supplied with the evaluation kit.
GND is the most positive voltage, and -VINA and -VINB
are the most negative voltages. Note that GND is common
for both channels on all three boards. Since most IC
signals are referenced to the negative rail, the user may
want to reference the voltmeter and oscilloscope GNDs to
the negative supply. However, be careful of earth GND
