| the A3361x and a3362x hall-effect switches are extremely temperature-stable and stress-resistant sensors. superior performance over temperature is made possible through dynamic offset cancellation, which reduces the residual offset voltage normally caused by device overmolding, temperature dependencies, and thermal stress. the two devices differ only in output polarity; the A3361x output current goes low in the presence of a south pole of sufficient strength; the a3362x output current goes high. each device includes on a single silicon chip a voltage regulator, hall-voltage generator, small-signal amplifier, chopper stabilization, schmitt trigger, and a constant-current open-collector output. an on-board regulator permits operation with supply voltages of 3.5 to 24 volts. noise radiation is limited by control of the output current slew rate. three package styles provide a magnetically optimized package for most applications. suffix xlh is a miniature sot23w low-profile surface-mount package, and suffix 'xua' is a three-lead ultra-mini sip for through-hole mounting. features internal current regulator for 2-wire operation resistant to physical stress superior temperature stability operation from unregulated supply solid-state reliability small size always order by complete part number: the prefix 'a' + the basic four-digit part number + a suffix to indicate operating temperature range (e) + a two-letter suffix to indicate package style, e.g., A3361elh . 2-wire, chopper-stabilized, hall-effect switches suffix code 'lh' pinning (sot23w) absolute maximum ratings at t a =+25 c nc x supply ground 12 3 dwg. ph-003-5 no (internal) connection pinning is shown viewed from branded side. 3361 and 3362 supply voltage, v cc ........................ 26.5 v reverse battery voltage, v rcc .......... -16 v magnetic flux density, b ........... unlimited package power dissipation, p d . see graph junction temperature, t j ............... +170 c operating temperature range, t a ............................... -40 c to +85 c storage temperature range, t s .............................. -65 c to +170 c data sheet 27621.50
