E-L9823013TR Application Field and Working Principle

Power management integrated circuits (PMICs) are semiconductor devices that monitor, control, and manage electrical signals associated with the supply, delivery, and consumption of electrical power. They are designed to manage the flow of power among subsystems, system rails, and other components of an electronic device. PMICs are available in a wide range of packages and classes such as discrete, programmable integrated circuits (PICs), and integrated circuits (ICs). One type of PMIC is the Power Distribution Switches, Load Drivers, and E-L9823013TR are one of such product.

E-L9823013TR Application Field

E-L9823013TR is a switch with three channels, which can be used in a variety of applications, such as ON-OFF switching in power distributions, voltage switching, load controlling of batteries, and general ON/OFF switch control. It also has dedicated ESD protection built-in, making it suitable for use in battery powered and mobile devices as well as high-voltage applications. It is available in a small form factor and packages, making it suitable for use in space-constrained devices.

E-L9823013TR Working Principle

The E-L9823013TR operates on a simple but effective semi-conductor-based approach. To ensure reliable switching operations, it needs a voltage drop between the two terminals and must maintain a certain voltage threshold in order to operate. The control circuit includes two MOSFETs, and the MOSFETs are triggered via a logic signal when the upper (non-inverting) gate voltage is sufficiently high to actuate the paired lower (inverting) gate of the other. This inversion and actuation is dynamic and ensures reliable switching operations, irrespective of the operating temperatures, or the supply voltage or other environmental conditions.

The E-L9823013TR includes an internal charge pump to power the internal logic and the low RDS MOSFETs. These internal MOSFETs ensure no turn-on delay, no latch, and no thermal runaway, which is a common failure mode in regular PMICs. Moreover, the E-L9823013TR is designed for maximum frequency up to 1 MHz, class-leading low resistance, low standby current, and fast switching, making it suitable for applications with high switching frequencies, such as boost and buck converters.

The E-L9823013TR also includes integrated protection functions such as over-temperature protection, over-current protection, and thermal overload protection, which helps to protect external circuitry from damage if they draw too much current. In addition to these protection functions, the E-L9823013TR also includes an internal protection diode which helps to reduce switching losses and minimize switching losses due to negative going input voltage transients.

The E-L9823013TR offers a low turn-on voltage, fast settling time, and high surge current, making it an ideal choice for a wide range of applications, including lighting, industrial, automated home appliances, and automotive.

Conclusion

In summary, Power Distribution Switches, Load Drivers, and E-L9823013TR are PMICs that provide reliable, fast switching, low turn-on voltage, and high surge current, which makes them suitable for a variety of applications. E-L9823013TR also includes integrated protection functions to protect external circuitry, making it a reliable and efficient solution in a variety of power management applications.
