.

Achieves linear speed control

.

Minimized speed fluctuations in the presence of line or load variations

.

Allows a minimum speed to be set

.

Soft start function

.

Settings using external capacitors and resistors

to support easier mass production of end products

.

Supports both PWM duty and analog voltage control inputs

.

[Added Function] : Supports origin shifting in the control function

.

[Added Function] : Adds a dedicated pin for setting the soft time.

This allows a longer start time to be set without reducing the response time when changeing speed.
