3 EVM Test Points, Jumpers, and Connectors
This section describes the test points, jumpers, and connectors on the EVM as well as how to connect, set
up, and properly use the EVM. Each device has independent signal connections, but all devices have a
common VCC and ground.
3.1 EVM Test Points
Table 2 lists the test points and functional descriptions. All pins of the device are broken out to test points
on the EVM.

Function Description
TP1 ENBA Enable driver A Internally pulled up, can be disabled when input is low
TP2 ENBB Enable driver B Internally pulled up, can be disabled when input is low
TP3 VCC Power supply Power supply for the device
TP4 FET_VDD Power supply Power supply for MOSFET
TP5, TP8, TP13-15 GND Ground Connected with ground
TP6, TP9, TP11 FET_OUTA MOSFET drain Connected with MOSFET drain
TP7, TP10, TP12 FET_OUTB MOSFET drain Connected with MOSFET drain
3.2 EVM Jumpers
Table 3 lists the jumpers on the UCC27423-4-5-Q1 EVM. As ordered, the EVM will have two jumpers
installed.

Description
J7 All ENBA to GND
Connect ENBA to GND to disable OUTA. Otherwise, connect ENBA to
VCC or leave it floating.
J8 All ENBB to GND
Connect ENBB to GND to disable OUTB. Otherwise, connect ENBB to
VCC or leave it floating.
3.3 EVM Input/Output Connectors
Table 4 lists the following 2-pin headers that are input/output connecters for each device.
