Glossary
flyback
A voltage spike seen across an inductive load when its supply voltage is suddenly
reduced or removed.
frequency input
An input that allows a frequency value to be read from an oscillating input signal.
gain
To increase the voltage level of an input signal to maximize the resolution of an
input.
general purpose input
An input that can be used as an analog, digital, or frequency input.
ground level shift
An undesirable condition in which the ground level elevates. This condition can
cause inputs to activate when they shouldn't.
half-bridge
The simultaneous use of a high-side switch and a low-side switch in order to
provide a load having both a battery voltage and a ground.
harness address pins
The pins a product uses to identify itself within a system.
H-bridge
A combination of two half-bridge circuits used together to form one circuit. H-
bridges provide current flow in both directions on a load, allowing the direction of
a load to be reversed.
high-side output
An output that provides switched battery voltage to an external load.
hysteresis
The tendency, either by nature or design, for a device or system to remain
temporarily (lag) in one state before switching to another. Hysteresis might be
intentionally added to electronic circuits prevent unwanted rapid switching. A
furnace, for example, is designed to remain on or off for some time after the room
temperature reaches the thermostat's set point.
