Output Isolation
The high current isolated outputs available through the ICM-20105 are configured for High Side
operation. The outputs are capable of 500 mA per output with a total of 3 A from the group of 8
outputs. The figure below shows the manner in which the load should be connected. The output
will be at the voltage that is supplied to the OUTSUP pin. Up to 30 VDC may be supplied to
OUTSUP.
The RPOUT resistor pack allows configuration of the active state of the outputs. For example
when you issue the SB1 command, the polarity of the resistor will determine whether the output is
turned on or off.
