MagnaChip Unveils New Voice Coil Motor Driver IC
MagnaChip Semiconductor Corp. announced that it has unveiled a Voice Coil Motor (VCM) driver IC (MAP1011) to support the autofocus function found in mobile phone and tablet PC cameras.
The MAP1011 model features a 10-bit resolution enabling 1,024-level precision control while utilizing the I2C high-speed controller methodology. The MAP1011 VCM driver also uses wafer level chip scale packaging (WLCSP) enhancing low-power operation and reducing standby power consumption. In addition, WLCSP provides user flexibility allowing mobile phone and tablet PC camera module developers a broad choice of product options based only on input and standby voltage criteria.
"We have continued to develop power semiconductor products specialized for mobile phones and tablet PC applications," said HK Kim, EVP and General Manager of MagnaChip’s Display and Power Solutions Division. "The MAP1011 VCM driver is the first of many future VCM driver IC designs that expands our power solutions product portfolio in order to meet the increasingly technical needs of our customers."
