MX887D
Circuit Description
The MX887D µPower Hall-Effect Switch consists of a Hall element, small signal amplifier, latch, and n-
channel open drain MOSFET driver. Offset cancellation rejects errors in signal stages and the influence
of mechanical stress on the Hall element. This technique together with a precision threshold generator
and comparator produce highly accurate magnetic switch points. The Hall element is activated for a small
fraction of an operating cycle, then latched in that sample state for the remainder of the period. By using
this technique, very low power consumption is achieved.
Electrical Characteristics
Over operating voltage and temperature range unless otherwise noted.
Notes: 1. Operating and release points will vary with supply voltage.
Magnetic Characteristics
Over operating voltage and temperature range unless otherwise noted.
Notes: 1. As use here, negative flux densities are defined as less than zero (algebraic convention) and -50G is less than +10G.
