PT5100 auto focus motor driver ic tel: 886-66296288 ? fax: 886-29174598 ? http://www.princeton.com.tw ? 2f, 233-1, baociao road, si ndian, taipei 23145, taiwan description the PT5100 is a single 10-bit dac with 102.3ma output current sink capability. it features an internal reference and operates from a single 2.3v to 5.5v supply. the dac is controlled via a 2-wire (i p p 2 p p c compatible) serial interface that operates at clock rates up to 400khz. the PT5100?s unique and proprietary slope control modes allow the user to cu stomize the output transient response thereby overcoming mechanical ringing associated with reduced form factor voice coil motors (vcms). the PT5100 incorporates a power-on reset circuit, which ensures that dac output powers up to 0v and remains there until a valid write takes place. it has a power-down feature that reduces the curr ent consumption of the device to 1 a maximum. the PT5100 is designed for autofocus, image stabilization, and optical zoom applications in camera phones, digital still cameras, and camcorders. the PT5100 also has many industrial applications, such as controlling temperature, light, and movement, over the range -40 to +85 without derating. the i p p 2 p p c address for the PT5100 is 0x18h. PT5100 has two versions ic about xshutdown pin: ver a: xshutdown pin is active low. (hard shutdown mode at v b b xshutdiwn b b =0v) ver b: xshutdown pin is active high.
