General Description
The MAX15096/A/D evaluation kit (EV kit) provides a
proven design to evaluate the MAX15096 hot-swap
controller with an integrated 6A MOSFET. The EV kit
is configured to pass 6A in a 2.7V to 18V hot-swap
application, thus providing a fully integrated solution.
The EV kit uses the MAX15096GWE+ in a 2mm x 2mm,
16-bump, 0.5mm pitch wafer-level package (WLP) with a
proven four-layer PCB design. As configured, the EV kit
is optimized to operate at 12V.
The EV kit can be used to evaluate all MAX15096A and
MAX15096D variants

Quick Start
Required Equipment
the banana jacks provided for the input and output. PCB
pads are provided to monitor and control the device signals. The EV kit operates between 2.7V and 18V up to 6A
load current capability.
● 12V, 6A DC power supply
Evaluating the MAX15096
● MAX15096 EV kit
● Voltmeter
Procedure
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 a shunt is installed across pins 1-2 on
jumper JU1. Also ensure that jumpers JU2 and JU4
are opened and jumpers JU3 and JU5 are closed.
2) Turn on the power supply and set the supply to 12V,
then disable the power supply.
The EV kit can be used to evaluate the MAX15096,
with the MAX15096GWE+ installed. The MAX15096A/
MAX15096D are pin-to-pin compatible with the
MAX15096. Refer to the device data sheet for details on
the MAX15096A and MAX15096D.
Circuit Breaker (CB)
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 (R5) or a potentiometer (R11) to set the
current limit. See Table 1 for shunt positions.
3) Connect the positive terminal of the power supply to
the IN banana jack on the EV kit. Connect the negative
terminal of the power supply to the GND banana jack.
The circuit-breaker threshold can be set according to the
following formula:
4) Enable the power supply.
where ICB is in A and RCB (the resistor between CB and
ground) is in Ω.
5) Verify that the voltage between the OUT and GND
banana jacks is 12V.
6) Verify that the internal regulator voltage (REG) is 3.3V.
7) The EV kit is now ready for additional evaluation.
Detailed Description of Hardware
The MAX15096 EV kit provides a proven design to
evaluate the MAX15096. The EV kit can be conveniently
connected between the system power and the load using

Evaluation Kits

Setting the Output Slew Rate
connected to UVOV. The EV kit’s undervoltage-lockout
threshold is set to 7.1V (typ) and the overvoltage-lockout
threshold is set to 15.8V (typ). Refer to the device data
sheet for mor details.
An external capacitor (C3) is connected from GATE to
GND on the IC to reduce the output slew rate during
startup. During startup, a 5.9µA (typ) current is sourced to
enhance the internal MOSFET with 10V/ms (typ). C3 can
be calculated according to the following formula:
TIMER
Jumper JU5 connects TIMER to REG, which sets the
total response time of the fast-trip comparator to less than
200ns (typ). For adjustable response time, open JU5 and
close JU4. JU4 connects TIMER to a 500kΩ potentiometer (R6).See Table 3 for shunt positions.
C3 = (IGATE x ∆t)/∆VGATE
where IGATE is 5.9µA (typ), ∆t is the desired slew rate,
and ∆VGATE is the voltage at the gate of the internal
MOSFET at turn-on.
Use the following formula to set the fast-trip comparator’s
response time:
Enable/Present-Detect Inputs
The EV kit features jumpers JU2 and JU3 to enable/
disable the output. JU3 allows simulation of PC Express
card being plugged in. OUT is enabled when PRSNT is
pulled low and EN is pulled high . If PRSNT is high, OUT
is not enabled, regardless of EN logic state See Table 2
for jumper positions.
tFCD = 0.2 + R6 x 22.9 x 10-3
where tFCD is the fast-trip comparator response time in µs
and R6 is the total resistance from TIMER to ground in kΩ
set by the 500kΩ potentiometer. Refer to the device data
sheet for more details.
Undervoltage/Overvoltage Lockout
The EV kit provides an option to configure the undervoltage/overvoltage-lockout threshold using a resistive
divider, R1 and R2 from IN to ground with the center tap
