*1 When a diode is used to protect the IC from destruction in case of reverse connection, the capacitor Cr must be inserted
to provide a regenerative current route. Similarly, a capacitor is needed in the power supply line, even if no diode is
used.
*2 The Hall element is supplied with a constant-voltage bias of approx. 1.27V from the HB pin. This ensures stable output
with good temperature characteristics from the Hall element. Because the LB1964M incorporates a Hall amplifier with
low offset, it provides coil output with a stable duty.
*3 The Hall amplifier does not have a hysteresis characteristic. The OUT1 and IN- pins are at the same phase, and by
arranging the two pins next to each other, chatter during phase switching is prevented. However, if the wiring leading
to the IN- pin is long, some noise interference may occur. In such a case, the following steps should be considered:
(1) Arrange parts layout with priority to proximity of Hall element and IC, to allow short Hall element output wiring.
(2) Insert a resistor of about 10 to 100 kW between OUT1 and IN- to create a hysteresis characteristic.
