one to make contact. It is used in some applications to
hold the IC’s in reset until all pins are have made good
contact. If this is desired, the user must also remove the
jumper caps on JP1A and JP1B (Control Board). When
this is done the A3 ground trace on the Control board is
disconnected from the main ground trace on the control
board (see figure 7).
make contact; connected to the UV/OV resistor divider on
both channels)
effectively eliminating the shorter pin if it has been
modified. If the SHORT GND function is desired simply
disconnect the jumpers and the UV/OV resistor divider will
only be connected to the short pin ground trace (A3).
signals are brought over to the LOAD board (TPPGA,
TPPGB) in the event the user needs them (for example, to
enable a brick regulator).

LOAD Board Labels
CAUTION HOT
The load resistors are mounted on the bottom of the LOAD
board, but the heat can be felt through the top of the board.
Be careful how you handle the board, especially while
gripping it for plugging or unplugging.
Edge Connector Pins (P2)
• Top pins B6, B5, B4 = -VOUTB
• Top pins B3, B2, B1 = -VOUTA
• Bottom pins A5, A4, A3, A2 = GND
• Bottom pins A1 = PWRGDA; A6 = PWRGDB
Over-Current latch by momentary shorting the UV pin to
the negative supply rail.
DIS pin low or high to control the GATE drive. Also used to
reset the Over-Current latch by toggling high to low.
Control board to main ground (A1, A2, A4-A5). Both
jumpers should be removed if the user wishes to simulate
last pin contact. In this case only the A3 trace will connect
to R4. Also note that the A3 trace on the Bus board must
be shortened by the user.
toggle switch. By removing the jumper cap, the user can
drive the disable pin externally with a signal generator or
external logic referenced to -V
to the red fault LED indicator (D5A/B). This jumper should
be removed for the ISL6152 (H version) because the LED
circuit is not valid; the LED would remain on for either
output state. Also the jumper should be removed if the
LED circuit interferes with the logic levels needed
externally (such as for a brick regulator). The present
board clamps the output to ~4.5V when the LED is on.
Note that this circuit may not be the most efficient or cost-
effective; it is just meant to be functional for the Eval
board.
LED comes on if the PWRGD pin on the ISL6142 goes
high; it represents some kind of fault, usually a shorted
output or an Over-Current shutdown. The LED will also
turn on if the FET is turned off due to a UV or OV fault. It
will turn back off when the supply is back within tolerance.
They turn on only when the Over-Current fault latch is set
due to a current limit time-out. The LED will turn off when
SW1A/B is pushed or SW2A/B is toggled high to low
