IL1815 Description
The IL1815 is an adaptive sense amplifier and default gating circuit for motor control applications. The sense amplifier provides a one-shot pulse output whose leading edge coincides with the negative-going zero crossing of a ground referenced input signal such as from a variable reluctance magnetic pick-up coil. In normal operation, this timing reference signal is processed (delayed) externally and returned to the...
