Product Overview
The SL1254-5 is a micro-power, high-sensitivity S-pole unipolar Hall effect switch sensor. It integrates a Hall element, voltage regulator, signal amplification and processing module, dynamic offset cancellation module, and a CMOS output stage. Utilizing advanced Bi-CMOS technology and an optimized circuit structure, the SL1254-5 achieves very low input error feedback. Its dynamic offset cancellation technology effectively eliminates offset voltages caused by packaging stress, thermal stress, and temperature gradients, enhancing device consistency. Packaged in a miniaturized SOT-553 surface-mount package, this device offers high performance and market advantages. It operates within a temperature range of -20C to 85C and is suitable for applications such as brushless motors, instrumentation, PDAs, and laptop computers.
