TPS3700 Window UV & OV Test Point Expected Measurement Range Calculator
Inputs:
Input Voltage:
Series Divider Resistors:
Note that the resistors can, with very low probability, be ouside of their tolerance values. It is recommended to double the rated tolerance for a 2x safety margin.
Multimeter Specifications:
MM Input Resistance on mV range.
MM DC accuracy on mV range.
Intermediate Calculations & Check Values:
MM Input resistance accuracy (rule of thumb).
Test Point Calculations & Check Values:
Exected Multimeter Test Point Voltages:
TP: UV Testpoint Range:
to
UV threshold is 394.5 mV nominal
TP: OV Testpoint Range:
to
OV threshold is 400 mV nominal
Note: the expected values changes with +Vin and multimeter specifications (entered at top of sheet)
Measurements outside of the expected range mean that the resistive divider circuit will need to be repaired to bring it back into specification
