5CH Motor Driver
PT5660
DESCRIPTION
The PT5660 is a monolithic 5-Channnel CMOS H-bridge motor driver. It can drive one stepper motor,
one DC motor, and two coils. There also are several other flexible system solutions left to be utilized.
The current consumption can be hold at quite low level during standby or operation. And the active
power supply voltage range is from 2.5~5.5V. So the device is ideal for portable and battery powered
applications. The PT5660 is available in QFN40 Low Profile (0.75mm) small size (5mm × 5mm)
package. Performance is specified for -20℃ to +85℃ temperature range.
