PIN FUNCTIONS

Pin #

Name

Description

1

GND

Ground.

2

VCC

Input voltage supply.

3

FG/RD Speed indication or rotor lock fault indication output.

4

PWM

Rotational speed control PWM input pin. A PWM 12kHz to 48kHz is recommended in

normal operation. PWM is an internal pull-

up with 100kΩ of resistance to the internal LDO.

5

OUT2

Motor driver output 2. OUT2 is connected to the mid-point of the internal N-channel MOSFET

half-bridge.

6

OUT1

Motor driver output 1. OUT2 is connected to the mid-point of the internal N-channel MOSFET

half-bridge.
