This motor driver 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 wave current to deliver smooth and quiet motor operation. Additionally, it offers automatic lead angle control to improve drive efficiency. It is recognized 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.
