Microcontroller | Option 1 | Option 2 | Option 3 |
|---|---|---|---|
Name | STSPIN32F0 | STM32L431 | STM32F051 |
Price/unit | $4.34 | $5.20 | $5.59 |
Pros | Integrated MCU with STM32F031, DC-DC, LDO, and gate driver for BLDC applications. Price can’t really be compared to other options. Physical design size of ESC would be very more compact since gate driver is integrated. | Existing design part of WARG, cheaper option | Used in previous ESC design from WARG, might be overkillrated as “overkill” by others |
Cons |
FET Selection
Main things to keep in consideration are the 20A max continuous current requirement, and any peak/transient current draw requirements from the motor.
