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.
