The A1128LUA-T is a programmable, unipolar Hall-effect switch in a 3-pin SIP through-hole package, designed for high-temperature automotive applications. It operates from 3 to 24 V with an onboard voltage regulator and features chopper stabilization for stable magnetic switchpoints across the -40°C to 150°C operating range. Programmable via the VCC pin, it allows adjustment of the operate point and output fall time to reduce EMI. The device includes protection against supply transients, reverse battery conditions, and output short circuits. Output polarity is field-programmable, and the maximum junction temperature is 165°C. It is AEC-Q100 automotive qualified.
The A1128 offers programmable switchpoints and hysteresis for design flexibility in high-temperature applications. Its chopper stabilization and integrated protection features ensure robust performance.
