MAX16814 Evaluation Kit
using the SYNC PCB pad and an external AC clock
signal. Test points are provided for easy access to IC’s
VCC and SGND.
To reconfigure the circuit for another current-sink
threshold, replace resistor R15 and use the following
equation to calculate a new value for the desired current:
Enable and UVLO
The EV kit features two jumpers to enable/disable U1
R15 =
1500
I LED
and configure the UVLO. Jumper JU1 enables the EV kit
when a shunt is installed and a shunt is also installed on
pins 1-2 of jumper JU2. Removing jumper JU1 disables
the EV kit. Configuring jumper JU2 to pins 2-3 allows
an external controller to enable the circuit and also dis-
ables UVLO resistors R1 and R2. Connect the external
controller to the ENABLE and SGND PCB pads. Refer to
the Enable section in the MAX16814 IC data sheet for
additional information. See Table 1 for jumper JU1 and
JU2 settings.
HB LED Current
The EV kit features a jumper to reconfigure the IC current
sinks on all 4 channels. When inserted, jumper JU3 con-
figures the current-sink limits to 150mA, and removing
where I LED is the desired HB LED current in amps and
R15 is the new resistor value for obtaining the desired
HB LED current. Remove jumper JU3 when configuring
for another current-sink level.
Channel 1–Channel 4 Current-Sink Disabling
The EV kit features jumpers to disable each channel’s
OUT_ current sink. When disabling a channel, install
a jumper in the channel’s respective OUT_ jumper.
Remove the shunt to use a channel’s OUT_ sink capabil-
ity. See Table 3 for jumper JU4–JU7 settings.
Table_3._Disabling_Channel_1–Channel_4_
(JU4–JU7)
the jumper configures the current-sink limits to 100mA.
See Table 2 for jumper JU3 settings.
