Lowest power magnetic switch uses nanoamps

The company is introducing its CT832 Digital Magnetic Switch, in the CT83X series, a multi- function switching device with high sensitivity, reliability and new lows in power consumption, that it positions as the industry’s lowest power consuming switch.

The solid-state magnetic switches provide higher reliability, faster frequency response, and extremely low power consumption in small form factor for battery powered applications. The CT83X has both a digital and analogue (proportional to field strength) output that serves multiple applications from a single switch with lower power consumption; when configured solely with a digital output it becomes the industry’s lowest power consuming switch with only 200 nA. It will operate with large air gaps and with fields a low as 3 mT (milli-Tesla). Packaging is SOT-23 or low-profile LGA, 1.4 x 1.4 mm.

“…[A] magnetic switch that combines the lowest power consumption with multiple functionalities to bring intelligence sensing to wide a variety of applications and systems, …across consumer goods, industrial applications, and IoT.” states Zak Deiri, Chief Sales and Marketing Officer, Crocus Technologies.

Approximately the size of a typical shunt resistor, the CT83X not only replaces it but provides added intelligence with enhanced switching and current monitoring capability. The CT83X either detects the magnetic field as generated by a permanent magnet or induced by a current-carrying conductor.
