AH9485 and AH9486 - Single Phase, All-In-One, Low Noise Smart Motor Driver Family

PublishTime：2021-08-10

●AH9485/86 are single-chip motor- driver ICs with an integrated H-Bridge switch and high-sensitivity Hall sensors for driving of small low-profile, single-coil, brushless DC motors and cooling fans. The output stage “soft switching” minimizes acoustic switching noise and electromagnetic interference (EMI) providing a low noise solution.
●For system flexibility the family offers versatile DC Voltage- and PWM speed control options.
●AH9485/86 feature rotor lock detect, shutdown and automatic restart.
●AH9485 features an open-drain Frequency Generator tachometer (FG) output, while AH9486 has a Rotation Detect alarm (RD) output, both to interface externally to monitor speed and rotation status.
●AH9485/86 are packaged in the flat-pin TSOT26F package to help place the device in a PCB cut-out to minimize overall component height.
