WSH41F
Unipolar Hall Switch IC with Complementary Outputs
Features:
Operate from 2.8V to 20V supply voltage.
On-chip Hall sensor.
Internal bandgap regulator allows temperature compensated operations and a
wide operating voltage range.
High output sinking capability up to 400mA for driving large load.
Lower current change rate reduces the peak output voltages during switching.
Built-in protection diode for reverse power supply fault.
General Description:
WSH41F is designed to integrate Hall sensor with complementary output drivers
and frequency generator together on the same chip, it is suitable for speed
measurement, revolution counting, positioning. It includes a temperature compensated
voltage regulator, a differential amplifier, a Hysteresis controller, two open-collector
output drivers capable of sinking 400mA current load. An on-chip protection diode 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.
WSH41F are rated for operation over temperature range from –20˚ C to 125˚C and
voltage ranges from 2.8V to 20V.
