Description:
NVE AD8xx and AD9xx GMR Switches are designed specifically for use with an
external high current output transistor in industrial control environments. These parts
provide the same precise magnetic performance NVEs GMR Switch is known for, with
the additional functionality of short circuit protection (SCP) for the output stage of the
circuit. The protection circuit is designed to shut off the output stage when a short circuit
condition exists; after a time interval specified by the user, the circuit turns back on. If
the short circuit condition still exists, the output stage is again shut off and the cycle
repeats. The use of this sensor, along with external reverse battery protection and
overvoltage protection, results in a bulletproof sensor assembly. A functional block
