SDC11557 - Single-Phase Full-Wave Motor Driver

Description

The SDC11557 is a single phase full wave motor driver for DC fan motors, and can apply to three type speed control methods.

The output signals of this IC are the amplifications of hall input signals.

It is suitable for both game machine and CPU cooler that need silent fans.

Features

  • Silent driver.
  • Built-in lock protection and auto restart function.
  • Low standby current (PWM=0), supply current less than 200uA.
  • FG output.
  • Built-in thermal protection circuit(RoHS Compliant).
  • Low duty start up.

Single-Phase Full-Wave Motor Driver Datasheet SDC11557 General Description The SDC11557 is a single phase full wave motor driver for DC fan motors, and can apply to three type speed control methods. The output signals of this IC are the amplifications of hall input signals. It is suitable for both game machine and CPU cooler that need silent fans. The device is built-in lock protection. When the fan is locked, the device will enter the lockup protection mode. It is also with thermal shutdown function. In normal operation, the supply current is less than 5mA. The SDC11557 is available in MSOP-8 package.
