Motor Driver IC for Sine-Wave Current Control: TB9080FG [Under development]

Brushless DC motor predriver IC designed to allow silent motor operation, which is increasingly required to offer a quiet cabin fro HEVs and EVs and during idling stop

The TB9080FG drives a motor with a sine current to deliver smooth and quiet motor operation. Additionally, the TB9080FG offers automatic lead angle control to improve drive efficiency.

The TB9080FG recognizes the target rpm of a motor from either the PWM duty signal or dc voltage. It then provides feedback control to match the actual rpm calculated from the motor’s Hall signals to the target rpm.

Its applications include air-conditioner blower motors, battery cooling fans and so on.
