Evaluating SIGN Output for
MAX9928/MAX9929
The MAX9928 and MAX9929 have a digital SIGN out-
put to indicate the direction of the load current flow
(charge vs. discharge current for a battery).
To evaluate current flowing in the opposite direction,
swap the position of the 12V supply and the electronic
load (connect the 12V supply to RS- and connect the
electronic load to RS+). Verify that the OUT voltmeter
still reads approximately 2.5V and the SIGN voltmeter
has changed to 0V.
Evaluating MAX9929 or MAX4372
The MAX9929 and MAX4372 are voltage output
devices with an internal 10kΩ R
OUT
resistor. When
evaluating these devices, leave the MAX9928 EV kit
R
OUT
open.
Refer to the MAX9928/MAX9929 IC data sheet and/or
the MAX4372 IC data sheet for more information.
