高灵敏度霍尔开关ST58L
Description
This Hall-effect switch is monolithic integrated circuits with tighter magneticspecifications, designed to operate continuously over extended temperatures
to +150°, and are more stable with both temperature and supply voltage
changes. The negative compensation slope is optimized to match the negative
temperature coefficient of low cost magnets.
Band gap regulation provides extremely stable operation over 3.8 to 40 VDC
supply voltage range. ST58L is capable of continuous 20 mA sinking output,
and may be cycled as high as 50 mA maximum.
FEATURES and BENEFITS
■ Superior Temp stability over -40 to +150 ℃ for Automotive or Industrial
applications
■ 3.8V to 40V supply voltage
■ High output current capability -50 mA absolute maximum
■ Quad-Hall design virtually eliminates mechanical stress effects
■ Temperature compensated magnetic
■ Digital current sinking output
■ SIP-3 pin in-line PCB terminals
POTENTIAL APPLICATIONS
■ Speed and RPM (revolutions per minute) sensing
■ Motor and fan control
■ Flow-rate sensing
■ Brushless dc motor commutation
■ Auto-motive transmission position
■ Robotics control
ABSOLUTE MAXIMUM RATINGS
Parameter Minimum Typical Maximum Unit
Supply voltage -40 - 40 V
Applied output voltage -0.5 28 V
Output current - - 50 mA

Note:
Absolute maximum ratings are the extreme limits the device will momentarily
withstand without damage to the device. Electrical and magnetic
characteristics are not guaranteed if the rated voltage and/or currents are
exceeded nor will the device necessarily operated at absolute maximum
ratings.
