A1225 Hall-Effect Latch

A1225 Description

A1225, A1227, and A1229 Hall-Effect Latch for High Temperature Operation .
These Hall-effect latches are extremely temperature-stable and stress resistant sensor ICs especially suited for operation over extended temperature r.

A1225 Features

* ▪ Symmetrical switchpoints ▪ Superior temperature stability ▪ Operation from unregulated supply ▪ Open-drain 25 mA output ▪ Reverse battery protection ▪ Activate with small, commercially available permanent magnets ▪ Solid-state reliability ▪ Small size ▪ Resistant to physical stress ▪ Enhanced ESD

A1225 Applications

* where duty cycle is an important parameter. The three basic devices (A1225, A1227, and A1229) are identical except for magnetic switchpoints. Each device includes on a single silicon chip a voltage regulator, Hall-voltage generator, temperature compensation circuit, signal amplifier, Schmitt trigger
