Hello,
we would like to use the current monitor output ISMON in order to save a dedicated OPamp circuitry or current sense monitor IC for an application where we use max. 2:1 analog dimming via ctrl input . This means the current sense amplifier will have a sense voltage between 50mV and 100mV. The datasheet specifies:
| ISMON Voltage | VISP - VISN = 100mV (100%), VISP = 12V VISP - VISN = 10mV (10%), VISP = 12V |
0.965 1.000 1.030 80 100 120 |
V mV |
So approx. +/-3.5% for 100mV and +/-20% for 10mV sense voltage across VISP and VISN for Ta = 25°C. What accuracy can we expect for 50mV sense voltage over full operating temperature range (-40°C to 85°C) ? If you can provide a graph or similar, this would also help. Thanks in advance!
Regards Andreas
