The half-step is controlled by the following sequence (1)->(2)->(8)->(1) ->… , but for reverse side, sequence (1)->(8)->(7)->… . Moreover, the full-step is controlled by the following sequence (1)->(2)->(3)->(4)->(1)… , but for reverse side, sequence (1)->(4)->(3)->… . These channels are for DC motor Focus & Iris operation. Constant Current H-Bridge (Channel 6) Channel 6 is a fixed current drive for VCM motor Shutter operation. When set VREFCT to “L”, and voltage from VREF is 1.2V through voltage resistors divider 100KΩ & 20KΩ (refer Figure2), and that VC6 can be calculated 1.2V x 20/(100+20) = 0.2V.

Constant Current H-Bridge (Channel 6) (Cont.) current about 200mA=0.2V/1Ω i s limited by VC6 voltage. When the setup value of the weak excitation mode is changed, add a variable resistor between VC6 and VC6A pin to adjust the current limit (VREFCT set to “H”), for example, if VC6 & VC6A pin add a variable resistor and the value is 20KΩ , since this 20KΩ i s parallel with another 20KΩ, the equal resistor value is 10KΩ. So VC6 will be equal 1.2V x 10/(100+10) = 0.11V, the current limit is equal 0.11V/1Ω = 110mA. AD/A value direct connects to VC6 (VREFCT to “L”) is another method to control the current limit as well.
