Pinning is shown viewed from branded side.

The A3240-- Hall-effect switch is an extremely temperature-stable

and stress-resistant sensor 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, tempera-

ture dependencies, and thermal stress.

The 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-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.

The first character of the part number suffix determines the device

operating temperature range; suffix ‘E–’ is for -40°C to +85°C and

‘L–’ is -40°C to +150°C. Three package styles provide a magnetically

optimized package for most applications. Suffix ‘–LH’ is a modified

SOT-23 surface-mount package, ‘–LT’ is a miniature SOT-89/TO-

243AA transistor package for surface-mount applications; while suffix

‘–UA’ is a three-lead ultra-mini-SIP for through-hole mounting.
