J3
3-pin jumper header
Threshold Adjustment Option
Selection
•
Place a jumper between the
"ADJ" (pin 2) and "DAC"
(pin 1) positions to use the
DAC to set the B
OP
. Make
sure that resistor R7 is not
populated. See
for more details.
•
Place a jumper between the
"ADJ" (pin 2) and "APOT"
(pin 3) positions to use the
potentiometer to set the B
OP
.
Make sure that resistor R7
is not populated. See
for more details.
•
To set the B
OP
using a fixed
resistor, remove the jumper
on this pin so that no jumper
is populated. Add a resistor
to R7 based on the desired
B
OP.
This resistor should be
between 2 kΩ to 15 kΩ
See
for more
details.
•
To set the B
OP
using
an external voltage source,
remove the jumper on this
pin so that no jumper is
populated and also make
sure that resistor R7 is
not populated. The external
power supply should be
connected between the "ADJ"
(pin 2) pin and GND. The
applied voltage should be
between 0.16 V to 1.2 V. In
addition, the voltage source
must be able to sink 80 μA of
current within 4 μs for proper
operation.
J4
3-pin header
Probe here for TVCC and GND.
Probe here for TVCC (pin 1)
and GND (pin 3). If a jumper
is pressed on J2, TVCC is
connected to VCC on the board.
To power the TMAG5328 from
an external power supply that is
independent of VCC, remove the
jumper header on J2 and connect
the external bench power supply
between TVCC and GND.
