MXMM11X70GH2a3ll2s0witch
The MXM1170 is an integrated Hall effect magnetic switch with dynamic offset cancellation, low power
consumption, and temperature stability of the magnetic thresholds for highly accurate applications. This
sensor is comprised of a Hall element, an offset cancellation circuitry, a low noise gain amplifier, a
comparator, and control logic in a single chip.
The MXM1170 supports for programmable function via single wired interface in order to provide more
flexible design by changing operation mode (omni-polar/bi-polar/uni-polar), operation threshold level, and
output port type. The MXM1170 has very thin DFN package and is suitable for mobile phones, consumer
electronics and industry applications
