Toshiba Offers Digital Output Magnetic Sensor Lineup With North, South or Both Pole Detection for On-Off Switches

Toshiba America Electronic Components has announced a lineup of magnetic sensors for use in applications such as on-off switches in mobile phones, notebook PCs, home appliances, and other products with open-close mechanisms that use on-off, hibernate or other system-based signals determined by the distance or angle of the sensor to a magnet. Three series of sensors, TCS20, TCS11 and TCS10, developed by Toshiba Corp. (Toshiba), detect magnetic flux from north or south magnetic poles, or both. Combined, the three series include 13 devices with a choice of three levels of magnetic flux sensitivity, magnetic pole detection and push-pull, open-drain or inverted open-drain digital output, and three types of packages.

Four sensors in the TCS20 Series provide two different levels of magnetic flux density and two different packages which meet different application requirements and feature both north- and south-pole detection. The TCS20DPR and TCS20DPC provide push-pull digital output, while the TCS20DLR and TCS20DLC feature an open-drain output system. TCS20xxR devices feature high magnetic flux sensitivity of 4.4mT (max.) for the BON detection level and 0.9mT (min.) for the BOFF release level. They are offered in three-pin SOT-23F packages measuring 2.4mm x 2.9mm x 0.8mm. TCS20xxC devices feature an ultra thin package with high magnetic flux sensitivity of 3.8mT (max.) for the BON detection level and 0.3mT (min.) for the BOFF release level. They are offered in six-pin CST6C packages measuring 1.5mm x 1.15mm x 0.38mm. The sensors utilize a very low average power consumption current of 12.8 microamperes (ave.), with an operating voltage of 3.3V. They can operate over a wide operating voltage range from 2.3 to 3.6V.
