Hall-effect sensor IC promotes energy efficiency

Hall-effect sensor IC promotes energy efficiency

The SL353 series micropower omnipolar digital Hall-effect sensor IC uses a BiCMOS IC design technology, making it possible to add more performance and functionality while reducing the size of the IC (compared to bipolar technology). Its low supply voltage (as low as 2.2 Vdc) with a very low average current (1.8 µA typ for the SL353LT — the lowest in its class), reduces power consumption, extends battery life, and promotes energy efficiency.

The product is available in two duty-cycle configurations: the SL353HT offers a duty cycle of 13% typ and a drain current of 0.33 mA typ, and the SL353LT a duty cycle of 0.013% typ and a drain current 1.8 µA typ.

Features include built-in timing circuitry, push-pull output (that needs no pull-up resistor), and a non-chopper-stabilized design (means that no filter is needed to compensate for the noise generated by this technique). The series responds to either a north or south pole. The sensor ICs are available in SOT-23 packages. (Contact company for pricing — available now.)
