Part Number: SG3524
Other Parts Discussed in Thread: DRV8251,

hi ,

I want to design a compressor that conforms to two different architectures

item1 have 3pin input,The middle tap of the coil is connected to 12v

item2 have 2pin input,

I want to use DRV8251 to control item1,it's can't normal work,

Is there an ic solution that can be shared by both?

Or do you have any suggestions on how to package SG3524 and MOSFET together?

Hi Jacky,

1. DRV8251integrates gate drivers and FETs. The inputs are PWM controller signals. This device can provide up to 4.1A to drive a motor.

2. SG3524 is just a PWM controller. You need gate drivers and FETs to drive a motor.

Are you looking for an IC who integrates gate driver and FETs to drive a motor? If that is the case, you still need a PWM controller like SG3525 to drive control signal to the gate drivers. I recommend searching for motor driver applications in this webpage HERE from ti.com. Depending on what you are looking for (gate drivers, FETs, bias supplies), it provides different part numbers and reference designs.

If you have any further questions, please let me know replying to this thread.
