CT831BV-HS3 Crocus

CT83x Series Omnipolar Digital TMR Latch/Sensor for Consumer & Industrial Applications Product Description The CT83x Series of integrated omnipolar magnetic latches and analog sensor are designed for consumer and industrial switching applications. It is based on Crocus Technologys patented Magnetic Logic Unit (MLU) technology with integrated CMOS process to provide a monolithic solution for superior sensing performance. SOT-23 Package This series of magnetic latches feature an industry leading low power consump- tion as low as 200 nA. They are capable of handling large air gap applications with low magnetic fields down to 0.9 mT with best in class high frequency perfor- mance. The CT83x is offered in active-low push-pull CMOS and open drain con- figuration for design flexibility. The latches are available in a low profile and small form factor 4-lead LGA and 3-lead SOT-23 packages, providing cost effective and space-saving solutions for high volume manufacturing.
