Toshiba America Electronic Components (TAEC) has declared the launch of a series of magnetic sensing units for on-off switch applications in notebook PCs, home appliances mobile phones and other solutions with open-close functionality. It uses hibernate, on-off or other system-enabled signals identified by the angle or distance of the sensing unit to a magnet.
Three ranges of sensors, TCS10, TCS11 and TCS20, devised by the company determine magnetic flux from the north magnetic pole or south or both. By linking all the three ranges, 13 devices have been developed with an option for three levels of sensitivity towards magnetic flux, magnetic pole determination and open-drain, push-pull or inverted digital output with open-drain and three modes of packages.
The four different types of TCS20 Series sensors supply two varied levels of magnetic flux density and two various packages for satisfying different demands and exhibits both north- and south-pole determination. The TCS20DPC and TCS20DPR deliver digital output with push-pull operation, in comparison with the TCS20DLC and TCS20DLR having an output system with open-drain functionality. The TCS20xxR systems show a maximum of 4.4mT magnetic flux sensitivity in the BON determination level and minimum 0.9mT for the BOFF discharge level. They are supplied in SOT-23F three-pin enclosures in the range of 2.4mm x 2.9mm x 0.8mm.
The TCS20xxC system has a thin package with a maximum magnetic flux sensitivity of 3.8mT for the BON identification level and a minimum of 0.3mT for the BOFF discharge level. They are provided in CST6C six-pin enclosures with 1.5mm x 1.15mm x 0.38mm. These sensors require less average energy consumption of 12.8 µA with a working voltage of 3.3V. They are operative in 2.3 V to 3.6V range.
Another nine sensors in the TCS10 and TCS11 series employs various levels of magnetic flux with a maximum sensitivity of 2.5mT for the BON determination level and with a minimum of 0.3mT for the BOFF discharge level, featuring a less average energy utility of 8.5 µA with 2.3 V to 3.6V operating range. The TCS10 and TCS11 series are available in UFV five-pin enclosures, measuring 2.0mm x 2.1mm x 0.7mm.
The TCS11 series involves three systems with open-drain, inverted output. The TCS11SLU identifies south polarity, while the TCS11NLU identifies north polarity and the TCS11DLU both the poles. The TCS10 range features three output sensors with push-pull function and three open-drain outputs.
TCS10SPU determines south polarity within the push-pull output series and the TCS10NPU tracks north polarity, TCS10DPU identifies both the poles. The TCS10SLU checks south polarity with open-drain digital output and the TCS10NLU tracks north polarity, while the TCS10DLU identifies both the poles.
