UIM243XXB Wiring Terminal

For users want to use an external voltage to control the speed to facilitate the needs such
as microprocessor D/A control, UIM24302B provides a speed control voltage input port.
The external control voltage must share the common ground with the UIM24302B controller.

UIM243XXB With External Control Voltage.

The external control range must between -0.3V and 5.3V.
