A1220 Product details

Description

The A1220, A1221, A1222, and A1223 Hall-effect sensor ICs are extremely temperature-stable and stress-resistant devices especially suited for operation over extended temperature ranges to 150°C. Superior high-temperature performance is made possible through dynamic offset cancellation, which reduces the residual offset voltage normally caused by device overmolding, temperature dependencies, and thermal stress. Each device includes on a single silicon chip a voltage regulator, Hall voltage generator, small-signal amplifier, chopper stabilization, Schmitt trigger, and a short-circuit protected open-drain output to sink up to 25 mA. A south pole of sufficient strength turns

the output on. A north pole of sufficient strength is necessary to turn the output off.



Features and Benefits

▪ Symmetrical latch switchpoints

▪ Resistant to physical stress

▪ Superior temperature stability

▪ Output short-circuit protection

▪ Operation from unregulated supply down to 3 V

▪ Reverse battery protection

▪ Solid-state reliability

▪ Small package sizes
