Introduction to MAX809JTRG Application and Working Principle

Pulse Width Modulation (PWM) is a type of technology used in Pulse Width Modulated (PMW) integrated circuits (ICs), such as the MAX809JTRG. By controlling the width of the output pulse, the voltage or current of the output can be regulated. The MAX809JTRG PWM IC is a pulse width modulator that can be applied in various power supplies and circuits, such as those in the fields of industrial, automotive and consumer electronics, to provide adjustable electrical currents. The following sections will discuss the application fields, the general working principle of the MAX809JTRG as well as explain the details of how it works.

The Application Field of MAX809JTRG

The MAX809JTRG is a dual-channel PWM IC, specifically designed for applications in portable, adjustable power supplies. The MAX809JTRG achieves this by providing two independent control channels that can be independently set via a single resistor. It provides a quick, simple and cost-effective solution for applications that require adjustable output currents, such as motor drives and other high power devices.The IC can be used in a wide range of applications such as, battery powered portable devices, solar powered street lamps, industrial drives, automotive electronics and other industrial power supplies. The MAX809JTRG also integrates two drivers, so it can be used as a direct interface with FETL (Field Effect Transistor Logic) drivers, BC balanced modulators and other external control hardware.

Working Principle of MAX809JTRG

The MAX809JTRG is a two-channel PWM controller and this two-channel is designed for generating adjustable DC power for both LED and DC motor applications. The IC works by controlling the amount of power delivered to a load by using the pulse width modulation technique.The controller takes the input power supply and reduces it to the desired voltage level. The pulse width modulation technique is used to generate the output current. The modulation process utilizes a timer (typically an internal oscillator or an external clock) to determine the frequency of the modulation signal. The output current is determined by the pulse width of the modulation signal.The MAX809JTRG has two low side driver outputs, each of which has adjustable gates that can be used to control the current delivered to the load. The adjustable gates control the amount of power delivered to the load. The adjustment is done by connecting the adjustable gate to the PWM controller.The current flows from the output to the load through the low side driver and this current is regulated by the PWM controller. This regulation is done by switching the low side driver between the high and low states. The PWM controller will continuously adjust the width of the output pulse, allowing for optimal power delivery to the load.

Conclusion

The MAX809JTRG is an IC designed as a pulse width modulated IC for a wide range of applications in battery powered portable devices, industrial drives, automotive electronics and other industrial power supplies. It can generate an adjustable DC power output by utilizing a timer based signal with an adjustable gate to determine the output current. The MAX809JTRG is a low cost, simple solution for a wide range of applications, making it a great choice for any application that requires adjustable output currents.
