SL353

Micropower Omnipolar Digital Hall-Effect Sensor ICs DESCRIPTION The SL353 Series sensor ICs (Integrated Circuits) are small, versatile, digital Hall-effect devices operated by the magnetic field from a permanent magnet or an electromagnet. These sensitive devices are designed to meet a wide range of potential applications with low power requirements. The SL353 Series responds to either a North or South pole, meaning that they do not require the magnet polarity to be identified, providing an easier installation and potentially reducing system cost. These low-power sensing devices use BiCMOS (Bipolar Complementary Metal Oxide Semiconductor) technology and a timing circuit that turns the power on for only a short time it is off for the rest of the period (duty cycle) significantly reducing the average current consumption. Both products can operate from a supply voltage as low as 2.2 V, promoting energy efficiency. VALUE PROPOSITIONS SL353LT For device manufacturers who need ultra low power sensing for battery-operated, mobile applications, Honeywell’s SL353LT Omnipolar Hall-Effect Sensor IC provides an ultra low power (1.8 μA, 2.8 Vdc) sensor IC and helps minimize PCB (Printed Circuit Board) space, part count and cost for the entire application. Unlike other low power Hall-effect sensors, the SL353LT offers ultra low power sensing with significantly lower noise emissions and the ability to minimize PCB space and cost for the entire application as demonstrated by a non-chopper s...
