WSH130
Operates from 2.4V to 26V supply voltage with reverse voltage protection
Operates with magnetic fields from DC to 15kHz
On-chip Hall Sensor
On-chip temperature compensation circuitry minimizes shifts in on and off points
and hysteresis over temperature and supply voltage
Ideal sensor for speed measurement, revolution counting, positioning, and DC
brushless motors
Specifications :
Switching type: latch or non-latch type (S pole)
Latch: On(L) with magnetic
South
pole and Off (H) with
North
pole
Non-Latch: On (L) with magnetic
South
pole and Off(H) without magnetic field
Functional Description :
WSH130 is designed to integrate Hall sensor with output driver together on the same
chip, it is suitable for speed measurement, revolution counting, positioning, and DC
brushless motors. It includes a temperature compensated voltage regulator, a
differential amplifier, a Hysteresis controller and a open-collector output driver
capable of sinking up to 20mA current load. An on-chip protection resistor is
implemented to prevent reverse power fault.
The temperature-dependent bias increases the supply voltage of the hall plates and
adjusts the switching points to the decreasing induction of magnets at higher
temperatures. Subsequently, the open collector output switches to the appropriate state.
WSH130 are rated for operation over temperature range from
–40˚
C to 125
˚C
and
voltage ranges from 2.4V to 26V.
