PWMsisäisen

PWMsisäinen is a Finnish term that translates to "internal PWM" or "on-chip PWM". It refers to a Pulse Width Modulation (PWM) controller integrated directly onto a semiconductor chip, such as a microcontroller or a dedicated PWM IC. Unlike external PWM circuits that require separate components like timers and logic gates, an internal PWM controller is a built-in peripheral.

These integrated PWM controllers offer several advantages. They reduce component count, simplify circuit design, and often provide higher precision and programmability. Internal PWMs typically have dedicated registers for controlling parameters like duty cycle, frequency, and dead time. They can generate multiple independent PWM signals, making them suitable for controlling motor speeds, dimming LEDs, generating analog voltage levels through filtering, or driving other power electronics.

The specific features and capabilities of an internal PWM controller vary significantly depending on the chip architecture and manufacturer. Some advanced PWM controllers may include features like complementary output channels, fault detection, or synchronization capabilities. The implementation allows for efficient and often high-speed generation of PWM signals, directly controlled by the chip's internal logic or firmware. This integration is a common feature in modern embedded systems where precise control of power and signals is essential.
