Chassis Mount Resistors -- L50J5K0E Application Field and Working Principle

The L50J5K0E model of chassis mount resistors is an intelligent device that provides a variety of capabilities depending on the application. It can serve as an adjustable voltage divider, a wave shaper, an energy storage device, and a high-resolution digital-to-analog converter (DAC).

Application Field

The L50J5K0E is used in a wide variety of applications including power supplies, voltage regulators, current sources, and pulse control circuits. It is especially suited for high-resolution, low-power applications. It can be used as a voltage divider for developing the reference voltage in voltage references, as a switch for controlling the power supply voltage, or for current limiting. It is commonly used in power management units, motor controllers, and audio products. It is also useful for controlling battery charging and providing voltage control in other applications.

Working Principle

The working principle of the L50J5K0E is based on the principle of adjustable summing resistance. The resistor is controlled by an external signal that is converted to a logic-level voltage that is applied to the control terminal. The control voltage is then converted to a digital representation in the DAC, which controls the summing resistance (SA). This summing resistance acts as a voltage-divider network that adjusts the reference voltage for the power supply. The summing resistance value can also be changed by changing the resistance in the voltage divider network.

The L50J5K0E can also be used as a wave shaper. By changing the summing resistance, the wave shape can be modified. This feature makes it an ideal solution for current-limiting applications, as the voltage across the resistor can be adjusted to ensure proper protection and safe operation. Additionally, the L50J5K0E can be used as an energy-storage device, as it can store energy when the control voltage is higher than the reference voltage, and release it when the control voltage is lower than the reference voltage. The high-resolution DAC output of the L50J5K0E allows for precise current control when used as a current shaper.

Conclusion

The L50J5K0E is a versatile chassis mount resistor that can be used for a variety of applications. It has an adjustable summing resistance (SA), high power rating, low thermal resistance, excellent stability, high-resolution DAC output, and TTL controlled parallel switching. It can be used as a voltage divider, a wave shaper, an energy storage device, and a high-resolution digital-to-analog converter. With its wide range of capabilities, the L50J5K0E is an indispensable component in many electronics applications.
