Exceeding the maximum allowable power dissipation will result in excessive die temperature. Note 1: Absolute Maximum Ratings are those values beyond w hich the life of a device may be impaired. Exposure to absolute maximum rating conditions for extended periods may aff ect device reliability. Note 2: The maximum continuous current rating should refer recommend operating conditions (VDD, TA, TJ) to guarantee reliability.

A .4 - O ct., 2015 A P X 2 8 4 www .anpec.com .tw7 Fun ctio n D escrip tio n Output Switch Principle The APX284 builts in a Hall-effect sensor plane to sense the vertical magnetic flux density (B). There are two out- put drivers in APX284 to drive two-phase DC brushless motor. When the South pole magnetic field is close to the IC marking surface and the magnetic flux density higher than operate point (Bop), the DO pin output will turn ON and the DOB pin output will turn OFF. When the South pole magnetic field far away the IC marking surface and North pole magnetic field close to the IC marking surface until the magnetic flux density higher than release point (Brp), the DO pin output will turn OFF and the DOB pin output will turn ON.

Thermal Protection The APX284 has a thermal protection. When the internal junction temperature reaches 165 oC, the output devices will be switched off. When the IC’ s junction temperature cools by 30 oC, the thermal sensor will turn the output devices on again, resulting in a pulsed output during con- tinuous thermal protection.
