MAX5976B Evaluation Kit
Note: Indicate that you are using the MAX5976B when contacting these component suppliers.
• MAX5976B EV kit
• 12V, 10A DC power supply
• Voltmeter
The EV kit is fully assembled and tested. Follow the
steps below to verify board operation. Caution: Do not
turn on the power supply until all connections are
completed.
1) Verify that shunts are installed in their default position
2) Verify that slide switches SW1, SW2, and SW3 are set
3) Turn on the power supply and set the supply to 12V,
4) Connect the positive terminal of the power supply to the
5) Enable the power supply.
6) Verify that the voltage between the OUT and GND
7) Verify that the voltage at the internal regulator voltage
8) The EV kit is now ready for additional evaluation.
The MAX5976B EV kit provides a proven design to
evaluate the MAX5976B hot-swap controller with an
integrated 7A MOSFET. The EV kit can be conveniently
connected between the system power and the load
using the banana jacks provided for the input and output
voltage. PCB pads are provided to monitor and control
the device signals. The EV kit operates between 2.7V
and 18V with up to 7A load-current capability.
The EV kit can also be used to evaluate the MAX5976A
after IC replacement of U1 with the MAX5976AETE+. The
MAX5976A is pin-to-pin compatible with the MAX5976B.
Refer to the MAX5976A/MAX5976B IC data sheet for
details on the MAX5976A.

(SW1, SW2, SW3)
Jumper JU1 sets the current limit for the internal circuit
breaker (CB) of the device. The CB pin can be connected
to a fixed resistor (R8) or a potentiometer (R9) to set the
current limit. See Table 3 for shunt positions.
The EV kit provides an option to configure the undervolt-
age-lockout threshold. The undervoltage-lockout threshold
for the device is configured by the VIN voltage level divided
by R1 and R10 at the ON1 pin. Set slide switch SW1 to
position 1-2 before configuring the undervoltage-lockout
threshold. See Table 4 for JU2 shunt positions.
Slide switch SW1 controls the active-high enable pin
(ON1) on the device. See Table 5 for switch positions.
