Evaluation Kit
General Description
Features
The MAX15095A evaluation kit (EV kit) provides a proven
design to evaluate the MAX15095A hot-swap controller
with an integrated 6.6A MOSFET. The EV kit is configured
to pass 6.6A in a 2.7V to 18V hot-swap application, thus
providing a fully integrated solution. The EV kit uses the
MAX15095AGFC+ in a 2.5mm X 2.5mm, 12-pin, 0.5mm
pitch FC2QFN package with a proven four-layer PCB
design. As configured, the EV kit is optimized to operate
at 12V.
● 2.7V to 18V Operating Voltage Range
● Up to 6.6A Configurable Load Current Capability
● Banana Jacks for Input and Output Voltage
● Programmable Slew-Rate Control
● Selectable/Configurable Circuit-Breaker Threshold
● Configurable Overvoltage/Undervoltage Lockout
● Programmable Fast Comparator Response
● PG Output
The EV kit can be used to evaluate all MAX15095 and
MAX15095D variants.
● Defined Safe Operation Area
● Proven PCB Layout
Ordering Information appears at end of data sheet.
● Fully Assembled and Tested

Evaluating the MAX15095A
Quick Start
The EV kit can be used to evaluate the MAX15095A,
with the MAX15095AGFC+ installed. The MAX15095/
MAX15095D are pin-to-pin compatible with the
MAX15095A. Refer to the device data sheet for details
on the MAX15095/MAX15095D.

Circuit Breaker (CB)
Procedure
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.
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.
The circuit-breaker threshold can be set according to the
following formula:
I
= (R
/ 5920) - (V / 33)

2) Turn on the power supply and set the supply to 12V,
then disable the power supply.

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.
Setting the Output Slew Rate
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:
4) Enable the power supply.
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.

The MAX15095A EV kit provides a proven design to
evaluate the MAX15095A. The EV kit can be conveniently
connected between the system power and the load using
the banana jacks provided for the input and output. PCB
pads are provided to monitor and control the device sig-
nals. The EV kit operates between 2.7V and 18V up to
6.6A load current capability.

Enable/Present-Detect Inputs
TIMER
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.
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

Use the following formula to set the fast-trip comparator’s

The EV kit provides an option to configure the under-
voltage/overvoltage-lockout threshold using a resistive
divider, R1 and R2 from IN to ground with the center tap
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.
