MH251 Hall-effect sensor is a temperature stable, stress
-resistant, Low Tolerance of Sensitivity
micro-power switch. Superior high-temperature performance is made possible through a dynamic
offset cancellation that utilizes chopper-stabilization. This method reduces the offset voltage
normally caused by device over molding, temperature dependencies, and thermal stress.
MH251 is special made for low operation voltage, 1.8V, to active the chip which is includes the
following on a single silicon chip: voltage regulator, Hall voltage generator, small-signal amplifier,
chopper stabilization, Schmitt trigger, CMOS output driver. Advanced CMOS wafer fabrication
processing is used to take advantage of low-voltage requirements, component matching, very low
input-offset errors, and small component geometries. This device requires the presence of
omni-polar magnetic fields for operation.
The package type is in a Halogen Free version has been verified by third party Lab.

2 双节升压充电 远翔FP6291
The FP6291 is a current mode boost DC-DC converter. Its PWM circuitry with built-in 0. 2Q power
MOSFET make this regulator highly power efficient. The intemal compens ation network also minimizes
as much as 6 external component counts. The non-inverting input of error amplifier connects to a 0.6V
precision reference voltage and intemal sof-start function can reduce the inrush current.
The FP6291 is available in the SOT23-6L package and provides space-saving PCB for the
application fields.
