ATS276 COMPLEMENTARY OUTPUT HALL EFFECT LATCH ʳ General Descriptionʳ Features x x x x x x x x x On-Chip Hall Sensor with Two Different Sensitivity and Hysteresis Settings for ATS276 3.5V to 20V Operating Voltage 400mA (avg.) Output Sink Current Built-in Protecting Diode Only for Chip Reverse Power Connecting -20qC to 85qC Operating Temperature Low Profile 4 Pin SIP Package Lead Free package: SIP-4L SIP-4L: Available in “Green” Molding Compound (No Br, Sb) Lead Free Finish/RoHS Compliant (Note 1) ATS276 are integrated Hall sensors with output drivers, mainly designed for electronic commutation of brush-less DC Fan. This IC internally includes the regulator, protecting diode, Hall plate, amplifier, comparator, and a pair of complementary open-collector outputs (DO, DOB). While the magnetic flux density (B) is larger than operate point (Bop), DO will turn on (low), and meanwhile DOB will turn off (high). Each output is latched until B is lower than release point (Brp), and then DOᇬDOB transfer each state. For DC fan application, sometimes need to test power reverse connection condition. Internal diode only protects chip-side but not for coil-side. If necessary, add one external diode to block the reverse current from coil-side.
