NMH1000 Datasheet | NXP Semiconductors

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 parison 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 pared 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. 4 Ordering information Table 1. Ordering information Type number Package Name Description VSON Very thin small outline package, no leads, 6 terminals, 0.5 mm  pitch, 1.4 mm x 1.4 mm x...
