The A1250 is a Hall-effect bipolar switch designed for ring-magnet sensing, featuring chopper stabilization for temperature stability and robust EMC performance. It operates from a supply voltage of 3.0 V to 24 V and is rated for an ambient temperature range of -40°C to 150°C. The A1250LUA-T variant is supplied in a 3-pin SIP through-hole package. It has a south-polarity operate point of -10 to 25 G and a north-polarity release point of -25 to -5 G, with hysteresis of 5 to 25 G. The device is AEC-Q100 automotive qualified and ASIL Ready, with an open-drain output that is short-circuit protected. Magnetic field strength requirements must be maintained for reliable switching.
The A1250 is a highly sensitive Hall-effect latch/bipolar switch optimized for ring magnet sensing. It features chopper stabilization for superior temperature stability and robust performance in demanding applications.
