General Description
Features
The MAX15090B/MAX15090C evaluation kits (EV kit)
provide a proven design to evaluate the MAX15090B/
MAX15090C hot-swap controllers with an integrated 12A
MOSFET. The EV kit is configured to pass 12A in a 2.7V
to 18V hot-swap application, thus providing a fully inte-
grated solution. The EV kit uses the MAX15090BEWI+/
MAX15090CEWI+ in a 3.5mm x 2mm, 28-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.

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.

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

Setting Timeout Delay for EN (CDLY)
Undervoltage Lockout
Capacitor C4 is used to set the timeout delay for EN to go
low to prevent internal MOSFET shutdown after power-
up. This is set at a rate of 1s/µF. The EV kit is configured
for a 47ms timeout delay.
The EV kit provides an option to configure the undervolt-
age-lockout threshold. The undervoltage-lockout thresh-
old for the device is configured by the IN voltage level
dividedꢀbyꢀR1ꢀandꢀ(R2ꢀ+ꢀR3)ꢀatꢀtheꢀUVꢀpin.ꢀByꢀdefault,ꢀtheꢀ
undervoltage-lockout threshold is set to 10.8V.
Delayed EN
Overvoltage Lockout
The IC’s EN pin must be pulled low before the timeout
delay set by capacitor C4 elapses. The EV kit provides a
simpleꢀtimerꢀcircuitꢀcomprisedꢀofꢀU2,ꢀR7,ꢀandꢀC5ꢀtoꢀpullꢀ
the EN pin low before the timeout delay. Once PG asserts
asꢀopen-drain,ꢀR7ꢀbeginsꢀtoꢀchargeꢀC5ꢀtoꢀtheꢀoutputꢀvolt-
ageꢀ(OUT).ꢀWhenꢀC5ꢀchargesꢀtoꢀ2/3ꢀxꢀOUT,ꢀU2ꢀpullsꢀtheꢀ
EN pin low. The EV kit is configured to have EN pulled
low after ~22ms.
The EV kit provides an option to configure the overvolt-
age-lockout threshold. The overvoltage-lockout thresh-
old for the device is configured by the IN voltage level
dividedꢀbyꢀ(R1ꢀ+ꢀR2)ꢀandꢀR3ꢀatꢀtheꢀOVꢀpin.ꢀByꢀdefault,ꢀtheꢀ
overvoltage-lockout threshold is set to 13.2V.
Current-Sense Output (ISENSE)
The IC’s ISENSE pin is the output of an accurate current-
sense amplifier and provides a source current propor-
tional to the load current flowing into the main switch. The
factory-trimmed current ratio is set to 220µA/A. On the
EV kit, this allows producing a scaled voltage by routing
resistorꢀR6ꢀfromꢀISENSEꢀtoꢀGND.
JumperꢀJU2ꢀisꢀalsoꢀprovidedꢀtoꢀbypassꢀtheꢀtimeoutꢀdelayꢀ
and force EN low, if installed. See Table 2ꢀforꢀJU2ꢀsettings.
