Product Description
The APS13290 and APS13291 are three-wire, planar Hall-effect sensor ICs designed for operation over extended temperature ranges, up to 125C ambient and 175C junction temperatures. These precision Hall-effect latch ICs are ideal for industrial and consumer applications, offering enhanced performance for high-temperature environments. They feature reverse-polarity protection, output current limiter, overvoltage, and EMC protection for increased system robustness. The integrated silicon chip includes a voltage regulator, Hall plate, small signal amplifier, chopper stabilization, Schmitt trigger, and a short-circuit-protected open-drain output. Operation is triggered by a south pole to turn the output on and a north pole to turn it off. The devices are protected against transients and operate from supply voltages of 2.8 to 24 V. Available in through-hole (SIP) and surface-mount (SOT23W) packages.
