This video will focus on the motor analog driver portion, reviewing the H-Bridge architecture, on-chip protection circuitry, decay modes, thermal performance, on-chip control logic, and the overall performance and reliability of today's integrated motor driver ICs. This section will also briefly introduce the rest of the motor analog signal chain, including isolation devices, sense amplifiers, and high-performance ADCs.
1. AD8138 can be used to achieve
The single-ended to differential conversion circuit uses AD8138 from AD. This amplifier has a wide analog bandwidth (320MHz, -3dB, gain 1) and can realize the function
This is a typical "three-no" Bluetooth speaker with a unique shape. It supports Bluetooth, FM, audio input, and TF. It has multiple functions and a loud volume.The knockoff speaker is naturally not co
The following is the circuit diagram of my main control chip. I originally thought that the low-speed crystal oscillator would not be used, so I deleted the low-speed crystal oscillator and only kept
