CT8150PC-IS3 Crocus

CT81x Digital Unipolar TMR Latch for Consumer & Industrial Applications Product Description The CT811 and CT812 are integrated unipolar magnetic latches that are de- signed 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 unipolar magnetic latch features an industry leading low power consumption as low as 230 nA. It is capable of handling large air gap applications with low magnetic fields down to 1.5 mT with best in class high frequency performance. For design flexibility, the CT811 and CT812 are offered in active-low open drain and push-pull configurations respectively. These latches are available in a 3-lead TO-92S package and a low profile yet small form factor 3-lead SOT-23 package, providing cost effective and space-saving solutions for high volume manufactur- ing. TO-92S Package Application Examples Features and Benefits IoT devices High sensitivity, B as low as 1.5 mT OP Smartphones, tablets, and laptops Resistant to mechanical stress Door or lid closure detection Ultra-low power consumption as low as 230 nA Digital CMOS push-pull and open drain options Reed switch replacement Motor controllers Low profile and small form factor packaging Proximity detection RoHS Compliant Power switch or open-close detection Tamper-proofing for utility meters Fluid level detection 2018 Crocus Technology Page 1 Document Number CT81x Series Datasheet Rev 0.5 CT81x Digital Unipolar TMR Latch for Consumer & Industrial Applications Figure 1: CT81x Block Diagram CT81x (SOT23 Package) Block Diagram VDD 1 Open Analog State Drain/ 2 OUT MLU Front-End Machine Push-pull Output UVLO Biases Oscillator 3 GND 2018 Crocus Technology Page 2 Document Number CT81x Series Datasheet Rev 0.5
