7.2.4.2 Detailed Design Procedure
First, choose a target range of hysteresis vlaue to achieve. For this design example, 50mV of hysteresis is chosen as the target. Since the TLV7032 already has 10mV (typ) of internal hysteresis, the voltage output from the TMR Rotation Sensor must be scaled down by a factor of 5. This way, the 10mV of internal hysteresis gets scaled up by a factor of 5, resulting in 50mV of hysteresis. The minimum output HIGH level for the TMR Rotation Sensor used in Figure 47 is 5.25V. Since 5.25V is the minimum output high value, this can be used to substitute VIN from the Voltage Divider Equation in Figure 48. Since the voltage from the TMR rotation sensor needs to be scaled down by a factor of 5, the equation in Figure 48 can be rewritten as:
The above equation can be
solved for using standard resistor values, where
R1 = 100kΩ, and R2 = 24.9kΩ.
The minimum voltage seen at the noninverting pins
of the comparator when the output is HIGH is
1.05V. To make the device transition at 50% output
high level, the inverting pins of the TLV7032 must
be tied to a 0.525V reference.
