MAX16141 Evaluation Kit
Evaluates: MAX16141
General Description
The MAX16141 evaluation kit (EV kit) evaluates the
MAX16141 IC family. The MAX16141 is a diode controller
and protection device that protects systems against fault
conditions, such as reverse-current, overcurrent, input over-
voltage/undervoltage, short-circuit, and overtemperature.
The MAX16141 EV kit comes with the MAX16141AAF/V+
IC installed. The MAX16141 EV kit undervoltage/overvoltage
thresholds are set to 8.6V/36.2V, respectively.

One digital multimeter (DMM)
Procedure
Features
The EV kit is fully assembled and tested. Follow the steps
below to verify board operation.
Caution: Do not turn on power supply until all connections
are completed.
1)
Verify that shunts are installed onto their respective
default positions for jumpers JU1–JU3 (Table
1,
Table 2,
and
Table 3).
2) Connect the power supply between the IN and
SYSGND terminal posts.
3) Connect the DMM between the OUT and SYSGND
terminal posts.
4) Turn on the power supply.
5) Manually sweep the power supply from 8.6V
to 36.2V. Verify that the output voltage at OUT
approximately follows the input voltage at IN.
6) Increase the input voltage to 37V.
7) Verify that the output voltage is 0V (overvoltage
protection)
8) Set the input voltage to 12V and verify that OUT is
also about 12V.
9) Using an insulated shorting cable, take caution to
hold the insulated parts of the shorting cable while
shorting OUT to SYSGND, and verify that the output
voltage is 0V (Short circuit protection).
10) Remove the shorting cable between OUT and
SYSGND and verify that the output voltage is 12V.
11) Decrease the input voltage to 7V.
12) Verify that the output voltage is approximately 0V
(undervoltage protection).

MAX16141 Evaluation Kit
Evaluates: MAX16141
Detailed Description of Hardware
Overvoltage Protection
The MAX16141 EV kit evaluates the MAX16141 IC. The
MAX16141 is a diode controller and protection device that
protects systems against fault conditions such as reverse
current, overcurrent, input overvoltage/undervoltage,
short circuit and over temperature. The MAX16141
EV kit’s undervoltage and overvoltage thresholds are
configured to 8.6V and 36.2V, respectively.
The MAX16141 EV kit comes with the MAX16141ATE+
(16-TQFN) installed and is configured to operate normally
between 8.6V and 36.2V. Under normal operation, the
output follows the input. The output will shut down (0V)
when the input is risen above 36.2V (i.e., 37V or higher),
or drop below 8.6V (i.e., 7V or lower). The output will also
shut down when the load at the output goes above 5A, or
in an event of a short circuit at the output.
The MAX16141 EV kit shuts down the output when the
input voltage exceeds the upper input voltage limit set
by resistors R11 and R9 between the TERM and OVSET
pins of the MAX16141. Refer to the equation below to set
the overvoltage limit for the MAX16141 EV kit.
R11 = ((VOV_TH x R9)/VTH) - (R9 + 700Ω)
where,
VOV_TH is the desired overvoltage threshold.
R9 = 10kΩ
V
TH
= 0.5V (typ) threshold for OVSET and 700Ω is the
TERM switch typical resistance.
Undervoltage Protection
SHDN
The MAX16141 EV kit provides a jumper (JU1) to enable
or disable the MAX16141. Refer to
Table 1
for JU1 jumper
settings.
The MAX16141 EV kit shuts down the output when the
input voltage drops below the lower input voltage limit set
by resistors R10 and R8 between the TERM and UVSET
pins of the MAX16141. Refer to the equation below to set
the undervoltage limit for the MAX16141 EV kit.
R10 = ((V
UV_TH
x R8)/V
TH
) - (R8 + 700Ω)
where,
V
UV_TH
is the desired undervoltage threshold.
R8 = 10kΩ
V
TH
= 0.5V (typ) threshold for UVSET and 700Ω is the
TERM switch typical resistance.
SLEEP
The MAX16141 EV kit provides a jumper (JU2) to pullup
the active-low sleep mode input of the MAX16141. Refer
to
Table 2
for JU2 jumper settings.
GATE Snubber
For applications that require slower gate rise time than
what is achieved using a resistor from GRC to GND, an
external resistor and capacitor (snubber) network can be
added from GATE to GND. However, the recommended
value is 1kΩ resistor in series with a 10nF cap.
The MAX16141 EV Kit provides a jumper (JU3) to add or
remove the snubber at the power MOSFET gates. Refer
to
Table 3
for jumper settings.

Overcurrent Protection
The MAX16141 EV kit shuts down the output when
the load current exceeds the current limit set by the
OC_THRESHOLD (See MAX16141 IC data sheet) and
the sense resistor R1 between the RS and OUT pins of
the MAX16141. Refer to the equation below to set the
overcurrent limit for the MAX16141 EV kit.
RSENSE = V(RS-OUT)/IOCTH
where,
RSENSE is the sense resistor between RS and OUT in
Ω,
V(RS-OUT) is the overcurrent threshold in V (refer to the
IC data sheet for the proper value)
IOCTH is the desired overcurrent threshold in A.
Short-Circuit Protection
The MAX16141 EV kit shuts down the output in event
the output is shorted to ground. The output will resume
normal level, same as the input, when the short at the
output is removed.
Evaluating other ICs in the MAX16141 Family
The MAX16141 EV kit comes with the MAX16141AAF/
V+ installed. To evaluate other ICs in the MAX16141 IC
family, replace U1 with the desired IC and refer to the
MAX16141 IC data sheet for additional detail.
