The Silan SA276 is a brushless DC fan driver with built‑in Hall sensor, wide 3.5‑20 V range and reverse‑voltage protection.
The SA276 driver integrates a Hall‑effect sensor, reference voltage, pre‑amplifier, Schmitt comparator and complementary open‑collector outputs (DO, DOB). It includes a reverse‑voltage protection diode for the IC and is offered in a compact TO‑94 package.
Typical applications include brushless DC fans, brushless DC motors, rotary counters and speed measurement circuits. The datasheet provides absolute‑maximum ratings, electrical parameters, pinout, and example test circuits. This manual is written in Chinese.
