... RPM trip point that will fit the particular application. • Motor control • Power-up fault failure filter inertial delay time for output switching. The SS421L has an inverting in motor start-up output; the SS421H has a non-inverting output. circuits. Built-in temperature compensation is optimized to match the temperature coefficient of low-cost magnets and track their performance over temperature ...

... The open collector output can be used to drive external circuitry that applies a latching voltage to the program/oscillator pin to latch the IC output in the fail state. This latch mode used only on products with delay set times greater than five seconds and with inverted output version of the SS421L. 3. ...
