1.5 ESD Rating

1.6 Magnetic Characteristics

Over operating voltage and temperature range unless otherwise specified.

Notes: 1. As used here, negative flux densities are defined as less than zero (algebraic convention); -50G<+10G.

2. B

= 3V.

2 Circuit Description

The MX887P mPower Hall-Effect Switch consists of a

Hall element, small-signal amplifier, latch, and CMOS

push-pull output. Offset cancellation circuitry 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,

produces 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.
