With the development of technology, power management IC (PMIC) have become increasingly important in the field of electronics. PMIC products include Motor Drivers, Controllers, and EL Applications. Among these, TB62262FTG is a voltage-controlled type Motor Driver controller which belongs to PMIC. In this article, we will discuss the application field and working principle of EL applications and TB62262FTG.

EL Application Field and Working Principle

EL applications are mainly used in the field of electrical devices, such as digital cameras and mobile phones. This kind of application includes EL lamp components and printed circuits, and works as a backlight for electrical components. EL applications usually have low power consumption with high efficiency, and contain no mercury or halogen. The working principle of EL application is that when a voltage is applied to the thin film layers of electrodes of the lamp component, electrons and holes will be injected from the electrodes into the semiconductor layers, and then recombine with each other. This induced behavior will release light energy which is visible to the human eye.

TB62262FTG Introduction and Working Principle

TB62262FTG is a voltage-controlled type Motor Driver controller manufactured by Toshiba, mainly used in the field of automotive LED lighting and other related products. The output current can be up to 4A and the product has two configurable input terminals, allowing the user to adjust the current output dynamically. This product also has an integrated start-up circuit which can detect open lamp circuit and shorted lamp circuit, protecting the system from any potential damage. The working principle of this PMIC is that when a voltage is applied on the field-effect transistor (FET) gate of the integrated circuit, the channel of FET will be opened and allow current flowing. The voltage on the gate will affect the resistance of the channel and thus adjust the output current which working through the load.

Conclusion

In conclusion, EL applications and TB62262FTG are two important PMIC products, both of which are widely used in the field of electronics. EL applications use high efficiency and low power consumption structure while the TB62262FTG can provide up to 4A output current. Both of them will be used in further development of products in the coming years.
