SL353HT (HONEYWELL)

The SL353HT is an omnipolar Sensor IC, small, versatile, digital hall-effect devices operated by the magnetic field from a permanent magnet or an electromagnet. This sensitive device is designed to meet a wide range of potential applications with low power requirements. The sensor IC 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. This low-power sensing devices use BiCMOS 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 2.2V, promoting energy efficiency. The push-pull output does not require a pull-up resistor and can operate with very low current levels, potentially helping to reduce cost and minimizing the total current consumption.
