BM6258FS-E2

BM6258FS is a 3-phase brushless fan motor driver IC that adopts PrestoMOS™ as the output transistor and put in a small full moulding 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. Typical applications include air conditioners, air purifiers, water pumps, dishwashers and washing machines.

• 600V PrestoMOS™ built-in and output current is 1.5A
• Bootstrap operation by floating high side driver (including diode)
• 180° sinusoidal commutation logic
• PWM control (upper, lower arm switching) and phase control supported from 0° to 40° at 1° intervals
• Rotational direction switch and VREG output (5V/30mA)
• FG signal output with pulse number switch (4 or 12 compatible with 8-poles motor interface)
• Protection circuits provided: CL, OCP, TSD, UVLO, MLP and the external fault input
• Fault output (open drain) and 600V output MOSFET voltage
• Duty control voltage range from 2.1V to 5.4V
• ±1.5A (max) driver output current (DC) and ±2.5A (max) driver output current (pulse)
