High speed rotation is achieved with a 150-degree commutation system. Rotation is faster and more stable than with a sine-wave commutation system, and vibration is lower than in a conventional 120-degree commutation system. Adoption of low on-resistance (upper + lower: 0.24Ω (typ.)) ensures suppression of heat generated from increased motor current by a high frequency drive, realizing support of a large current drive of up to 3A.
Main Features of New Products
-
Small package
WQFN 36 (5mm x 5mm x 0.8mm) package that can be mounted on the limited board space of small fans. -
Space saving for boards
One-sensor drive and current detection resistor-less system save space previously required for mounting external components. -
High speed rotation
A 150-degree commutation system realizes faster and more stable rotation than a sine-wave commutation system and lower vibration than a 120-degree commutation system. -
Low loss
IC loss during motor operation can be suppressed by low on-resistance of 0.24 Ω (typ.).
