General DescriptionLDB嘉泰姆

The APX7343 is a single-phase full-wave motor driver forLDB嘉泰姆

DC fan motor. The output signal of this IC is the amplifiedLDB嘉泰姆

hall input signal. It is suitable for both game machineLDB嘉泰姆

and CPU cooler that need silent drivers. The device isLDB嘉泰姆

equipped with built-in lock protection. When fan is locked,LDB嘉泰姆

the device will enter the lockup protection mode. It is alsoLDB嘉泰姆

with thermal protection function. In normal operation, sup-LDB嘉泰姆

ply current is less than 5mA; however, in lock mode, it isLDB嘉泰姆

just around 150µA, moreover, this feature will shutdownLDB嘉泰姆
