APS12235

APS12205, APS12215, and APS12235 High-Temperature Hall-Effect Latches for Low Voltage Applications FEATURES AND BENEFITS Optimized for applications with regulated power rails □□Operation from 2.8 to 5.5 V AEC-Q100 automotive qualified Operation up to 175°C junction temperature Dynamic offset cancellation □□Resistant to physical stress □□Superior temperature stability Symmetrical latch switchpoints Output short-circuit protection Solid-state reliability Industry-standard packages and pinouts PACKAGES: Not to scale 3-pin SOT23W (suffix LH) 3-pin SIP (suffix UA) DESCRIPTION The APS12205, APS12215, and APS12235 Hall-effect sensor ICs are extremely temperature-stable and stress-resistant devices especially suited for operation over extended junction temperature ranges up to 175°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. The single silicon chip includes: a Hall plate, small signal amplifier, chopper stabilization, Schmitt trigger, and a shortcircuit-protected open-drain output. A south pole of sufficient strength turns the output on; a north pole of sufficient strength is necessary to turn the output off. For applications requiring operation from greater than 5.5 V or operation directly from a battery, refer to the A1220, A1221, or A1223. Two package styles provide a choice of t...
