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.
• 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 an internally set threshold:
– Binary state hardware pin.
– Binary state data bit(s), configurable as assert-high or assert-low, in an I2C accessible register.
3 Applications
• Electronic system wake-up: Detecting the proximity vs. lack of proximity to an included magnet when the
electronics are removed from its delivery packaging, to wake up the electronics.
• Laptop lid open / closed: Detecting the proximity vs. lack of proximity to a magnet mounted to laptop lid, to
trigger a status change, for example turn on / off the display.
• Door or window open / closed: Detecting the proximity vs. lack of proximity to a magnet mounted to a door,
lid, or window, to trigger a status change, for example an alarm.
