DESCRIPTION
Not used
MFR_READ_VMON returns voltage on VMON pin in Volts. External 16:1
voltage divider needed on VMON/TMON pin (pin 6) to voltage being
monitored.
READ_TEMPERATURE_3 returns TMON in °C. External 2:1 voltage divider
needed on VMON/TMON pin (pin 6) to SPS TMON pin.
Not used
Output 0 uses VSEN0, Output 1 uses VSEN1
Both outputs use VSEN0
