集成电路

General Description

This 3-phase Brushless Fan motor driver IC adopts

PrestoMOS™ as the output transistor, and put in a small

full  molding  package  with  the  180°  sinusoidal

commutation controller chip and the high voltage gate

driver chip. The protection circuits for overcurrent,

overheating, under voltage lock out and the high voltage

bootstrap diode with current regulation are built-in. It

provides downsizing the built-in PCB of the motor.

Features

 600V PrestoMOS™ Built-in

 Output Current 1.5A

 Bootstrap operation by floating high side driver

(including diode)

 180° Sinusoidal Commutation Logic

 PWM Control (Upper and lower arm switching)

 Phase control supported from 0° to +40° at 1° intervals

 Rotational Direction Switch

 FG signal output with pulse number switch (4 or 12)

 VREG Output (5V/30mA)

 Protection circuits provided: CL, OCP, TSD, UVLO,

MLP and the external fault input

 Fault Output (open drain)

Applications

 Air Conditioners; Air Purifiers; Water Pumps;

Dishwashers; Washing Machines
