Abstract
A biasing and transient protection circuit 10 which is used in combination with a field effect transistor 14 which selectively communicates a voltage signal which emanates from a battery 12 to a component or load 18. The circuit 10 selectively generates a substantially constant electrical voltage to bias the gate terminal 50 of the field effect transistor 14, effective to allow the field effect transistor 14 to allow the component or load 18 to operatively receive the battery voltage signal while concomitantly protecting the field effect transistor 14 from transient voltage damage.
