CONTROL BOARD
The ISL6142/52 EVAL1 Board Set is made up of 3 boards to
simulate live plug-ins (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
• Two independent channels for comparison measurements
• Channel B configured with socketed through-hole
This evaluation platform 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
components to facilitate device analysis
performance at -48V and some components will need to
be changed to evaluate the device at the extremes of the
operating voltage range. For example, the OV threshold is
set to 56V to safely manage the temperature of the load
board and accommodate the power dissipation rating of
the load resistors. The Over-Current threshold is set to
185mA with a 0.270Ω sense resistor (R1) for the same
reason. The lower threshold also allows the evaluation of
the current limit and hard fault response with more
standard/available supplies. Note that the board is
capable of operating at much higher voltages (-80V), and
currents (17A) with the appropriate application
components. When evaluating the device at lower
voltages, the user should keep in mind that the UV (turn
on) threshold is set at -44.5 volts. The device will shut
down the FET when the supply falls below 39.7V (135mV
hysteresis). Also, the brightness of the power good LED
fault indicators (D5A/B) is determined by the supply
voltage through a current limiting resistor. Operating the
