Typical Applications (continued)

8.2.4 Quadrature Rotary Encoder

A quadrature encoder for rotary motors/shafts utilizing a Tunneling Magnetoresitance (TMR) Rotation Sensor can

track the position of the motor shaft even when power is turned off, while the TLV7032 provides additional

hysteresis to prevent unwanted output toggling between quadrants. The TLV7032 can be used with other

sensing techniques as well, such as optical, capacitive, or inductive.

8.2.4.1 Design Requirements

TMR Rotation Sensors general have two digital, binary outputs that are 90 degrees out of phase. The TLV7032

can be used to provide additional hysteresis to ensure there isn't any unwanted toggling of the output when the

sensors are between the transition points of two quadrants. The TLV7032 already provides 10mV of typical

internal hysteresis. By dividing down the output voltage from the rotation sensor using a voltage divider, the

internal hysteresis will be scaled up by the same voltage divider ratio.
