AH8231 Datasheet | AiT Semiconductor

Ai T Semiconductor Inc. .ait-ic. HALL SWITCH OMNIPOLAR HALL EFFECT SWITCH IC DESCRIPTION Features The AH8231 is designed to integrate pole independent Hall sensor with output driver together on the same chip. Either North or South magnetic field with sufficient strength will turn the output on (low). In the absence of a magnetic field, output is off (high). The polarity independence allow AH8231 to easily replace reed switches for superior reliability and case of manufacturing. To improve stability, it includes a temperature pensated voltage regulator, a differential amplifier, a Hysteresis controller, and an open collector output driver capable of sinking up to 20m A current load. The temperature dependent bias increases the supply voltage of the hall plates and adjusts the switching points to the decreasing induction of magnets at higher temperatures. Subsequently, the output can keep switching on/off on more precise switch point regardless to the ambient temperature. AH8231 are rated for operation over temperature range from -20℃ to +85 ℃ and voltage ranges from 2.4 V to 26 V. - Operates from 2.4 V to 26 V supply voltage - Operation with North or South Pole - On chip Hall Sensor and driver - On chip temperature pensation circuitry minimizes shifts in on and off points and hysteresis over temperature and supply voltage - On chip voltage regulator to stabilize On/Off switch point - Wide range operating temperature -20 ~ +85℃ - On (L) with South or North magnetic field and Off (H) with No magnetic field TYPICAL APPLICATION AH8231 is available in a SOT-23 and TO-92S packages.
