DESCRIPTION

The PT5111 is a semiconductor integrated circuit that

incorporates driver circuits suitable for the motors of

digital cameras. The current consumption can be hold

at quite low level during standby or operation. And the

active power supply voltage range is from 2.7~5.5V.

So the device is ideal for portable and battery powered

applications.

The PT5111 is available in QFN40 (5mm × 5mm)

package. Performance is specified for -20℃ to +85℃

temperature range.
