Notes:

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

2. BOPX = operating point (output turns ON); BRPX = release point (output turns OFF).

3. Typical data is at 25°C and VSUPPLY = 3V.

2 Circuit Description

The MX887P Power 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.
