A.2 - Jul., 2005 APX6223 www.anpec.com.tw10 Function Descriptions The APX6223 CMOS single chip builds driving capability for Digital Still Camera Exposure /Shutter/Focus/Zoom motor operation. The APX6223 can meet maximum various combinations of motor types inside of the DSC. The four groups of the independent inputs from host to control drive motor operations. The BRK selection pin can set 2 types of operations for channels 1~4 H bridge, which can set brake function for voltage control H bridge if BRK set “L”. Stepping Motor Control Refer the list below table for stepping motor control, which is defined as half-step and full-step motor control. 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.

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 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.
