Product Details

The A3240-- Hall-effect switch is an extremely temperature-stable and stress-resistant sensor especially suited for operation over extended tem per a ture ranges to +150Â°C. Superior high-temperature per for mance is made possible through dynamic offset cancellation, which reduces the residual offset voltage normally caused by device overmolding, tem per a ture de pen den cies, and thermal stress.

The device includes on a single silicon chip a voltage regulator, Hall voltage generator, small-signal amplifier, chopper sta bi li za tion, Schmitt trigger, and a short-circuit protected open-collector output to sink up to 25 mA. A south pole of sufficient strength will turn the output on. An on-board regulator permits operation with supply voltages of 4.2 to 24 volts.
Three package styles provide a magnetically op ti mized pack age for most ap pli ca tions. Package type LH is a modified SOT23W surface mount package, LT is a miniature SOT89/TO-243AA transistor package for surface-mount applications; while UA is a three-lead ultra-mini-SIP for through-hole mounting. The LH and UA packages are also available in a lead (Pb) free version (suffix, â€“T) , with a 100% matte tin plated leadframe.
