NMH1000 - Magnetic switch

Description

The NMH1000 is a hall effect magnetic field switch.

The switch is most sensitive to a vertical field passing through the top-to-bottom surfaces, orthogonal to the plane of the application printed circuit board.

Features

  • Threshold selection 3-state hardware pin.
  • Threshold selection data bit(s) in an I2C accessible register.
  • Sample rate selection 3-state hardware pin.
  • Sample rate selection data bit(s) in an I2C accessible register.
  • Mode selection hardware pin to select between standalone or I2C serial interface.
  • Mode selection data bit(s) in an I2C accessible register.
  • Two types of output indicate the absence of a magnetic field as compared to.

NMH1000 Magnetic switch Rev. 3 — 18 October 2023 Product data sheet 1 General description The NMH1000 is a hall effect magnetic field switch. The switch is most sensitive to a vertical field passing through the top-to-bottom surfaces, orthogonal to the plane of the application printed circuit board. The switch operates at low voltage, low current, low output data rate, and is a small physical size. Processing of input consists of functional blocks such as a configurable state machine, analog-to-voltage conversion of the input, and comparison to generate the bi-state output, arranged in linear succession. 2 Features and benefits • Threshold selection 3-state hardware pin. • Threshold selection data bit(s) in an I2C accessible register. • Sample rate selection 3-state hardware pin.
