High sensitivity of 7 Gauss typ., 11 Gauss max. (SM351LT); 14 G typ., 20 Gauss max. (SM353LT) suitable for a wide range of applications with large air gaps, small magnetic fields and low power requirements. Average current of 360 nA typ. (SM351LT) and 310 nA typ. (SM353LT) allows for use in battery operated equipment. Responds to either a North or South Pole, eliminating the need for the magnet polarity to be identified. Push-pull output eliminates the need for external resistors and helps reduce production costs. Non-chopper stabilized design eliminates external noise generated by the sensor. SOT-23 package on tape and reel (3000 units per reel). Designed for potential use in a wide range of battery-operated applications including water and gas meters, electricity meters, industrial smoke detectors, exercise equipment, security systems, hand-held computers and scanners; white goods such as dishwashers, microwaves, washing machines, refrigerators and coffee machines; medical equipment such as hospital beds, medication dispensing cabinets, infusion pumps; consumer electronics such as notebook computers, tablets, and cordless speakers.
