Frequently Asked Questions
What type of motor does the LM4570LQ control?
The LM4570LQ is a 3-phase brushless DC (BLDC) motor controller. It is designed to drive 3-phase BLDC motors commonly found in hard disk drive spindles, cooling fans, and small brushless motor applications, with a maximum output current of 192mA.
What is the package type for the LM4570LQ?
The LM4570LQ comes in an 8-pin Very Thin Profile Chip Carrier (VQCC-8) package with an integrated heat sink slug. The package body is square, measuring 0.08 inch per side, and is suitable for compact PCB designs requiring low-profile motor driver ICs.
What is the maximum output current of the LM4570LQ?
The LM4570LQ supports a maximum output current of 192mA (0.192A). This makes it appropriate for low-power 3-phase BLDC motor applications such as miniature fans, optical drives, and small spindle motors where precise low-current control is required.
Where can I buy the LM4570LQ and what is the price?
The LM4570LQ from Texas Instruments is available starting from $0.702 per unit. It is in stock and available for worldwide shipping through FindMyChip and authorized electronic component distributors. Submit a quote request for volume pricing and availability.
