Overview

Magnetoresistive Sensor ICs Nanopower Series Datasheet Magnetoresistive Sensor ICs Honeywell’s Nanopower Series Magnetoresistive (MR) Sensor ICs are ultra-sensitive devices designed to accommodate a wide range of applications with large air gaps, small magnetic fields and low power requirements.

The sensor ICs respond to either a North or South pole applied in a direction parallel to the sensor.

They do not require the magnet polarity to be identified, simplifying installation and potentially reducing system cost.

Key Features

  • High sensitivity: 7 Gauss typ. , 11 Gauss max. (SM351LT); 14 G typ. , 20 Gauss max. (SM353LT).
  • Nanopower: Average current of 360 nA typ. (SM351LT) and 310 nA typ. (SM353LT).
  • Supply voltage range: 1.65 Vdc to 5.5 Vdc; simplifies design-in.
  • Omnipolar sensing: Activates with either pole from a magnet.
  • Temperature range: -40 °C to 85 °C [-40 °F to 185 °F].
  • Push-pull output: Does not require external pull-up resistor.
  • Non-chopper stabilize.
