TIMING IN CASE
τ1 (or τ2) IS LONGER THAN FORWARD ROTATION SENSING TIME
Fig. 5
Note: CW/CCW pin is used for a reverse break; therefore, it is imposibble to use as reverse operation.

Position sensing input circuit
The common mode voltage range of pins (14), (15), (16), (17), (18) and (19) in position sensing input circuit is 2
V to VCC 0.5 V. Therefore, in case of VCC = 5 V, the range is 2~4.5 V.
Hysteresis of 7 mV (Typ.) is provided at the input to make the operation accurate.
Take care not to allow the hall output exceed the max. voltage 500 mVpp of the position sensing input as
shown in maximum rating for caution.
Hb and Hc waveforms operate similar to Ha.

Output circuit
As shown in the block diagram, in the output circuit, the Darlington emitters of PNP and NPN are of open
type on the upper side, and the lower side NPN is the open collector type.
Connect the external transistor in the same manner as that of the application circuit.
