VM147

Application Notes

The VM147 is a constant current driving IC for applications in Auto-Focus. The

supply voltage range VDD of VM147 is from 2.4V to 5.5V. The input range of

digital control pin PS, and digital I/O pins SCL and SDA, are defined such that

logic “High” is from 0.6*VDD to VDD+0.4V and logic “Low” is from –0.4V to

0.1*VDD. Therefore, the three digital pins are suitable controlled by 1.8V ISP.

the range of 0.1~0.22uF to match different VCMs.
