TDA5142T schematic block diagram and typical applications
Source: InternetPublisher:子丑寅卯 Keywords: BSP OTA timer oscillator Updated: 2021/05/27
The basic structure and working principle are shown in Figure 3-43.
The main include commutation logic, driver output stage, back electromotive force comparator, and independent operational
amplifier ( OTA ). There are also starting oscillators , adaptive commutation delay circuits, and timers ,
which can be set by external capacitors. In addition, there is a speed output stage and an
overheating protection circuit.
