Copyright ANPEC Electronics Corp. Rev. A.2 - Jul., 2005 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. If the package leads impedance is ignored (compare with RNF6 1Ω), that 10 www.anpec.com.tw APX6223 Function Descriptions (Cont.) Constant Current H-Bridge (Channel 6) (Cont.) current about 200mA=0.2V/1Ω is 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 is 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.
