PMIC - LED Drivers is a type of driver that controls the intensity of light-emitting diodes (LEDs). The MSL2024-INR is a type of PMIC - LED Drivers. It is typically used in applications where a range of LED currents and pulse widths must be accurately controlled in order to achieve the desired luminosity.

Introduction

The MSL2024-INR is a multi-channel LED driver IC from Toshiba. It is a type of PMIC - LED Drivers that can drive up to five LEDs at the same time. It is designed for applications where very accurate LED current and pulse width control is required in order to achieve the desired luminosity.

The MSL2024-INR has a wide input voltage range of 4V - 24V, and can control the brightness of LEDs from 0mA to 24mA with high accuracy. It also includes a wide range of protection functions including thermal protection, open-circuit protection, and over-voltage protection.

Application Field

The MSL2024-INR can be used in a wide range of applications, particularly those where high accuracy, controllability, and protection features are required. Some of the most common applications such as backlight illumination, displays, stage lighting and street illumination can benefit from this IC.

In backlight illumination, the MSL2024-INR can be used to accurately control the brightness of an LCD TV, monitor, or laptop display. This IC can also be used for automotive display illumination, where its wide input voltage range and over-voltage protection features are particularly useful.

The MSL2024-INR can also be used in stage lighting and street illumination. The 5-channel output of this IC allows the control over a wide range of colors, while the wide input voltage range ensures robustness and protection against voltage variations.

Working Principle

The MSL2024-INR works by controlling the pulse width and current of each LED channel. This is achieved by using pulse-width modulation (PWM), which sets a high state for a given amount of time, followed by a low state for another given amount of time. By making the pulse duration vary, a desired LED current and brightness can be achieved. The LED channels can also be programmed and dimmed until they are completely off.

The MSL2024-INR also includes a wide variety of protection features. It has a built-in thermal protection circuit that will shut off the channel if the temperature exceeds the specified limit. It also includes over-voltage protection, which will protect the LED from being damaged by excessive voltage. In addition, the MSL2024-INR also has a built-in open-circuit protection circuit that will stop the LED current if the LED is disconnected or shorted.

Conclusion

The MSL2024-INR is a type of PMIC - LED Drivers designed for applications where accuracy and protection are important. It can be used in a wide range of applications such as backlight illumination, displays, stage lighting, and street illumination. The MSL2024-INR works by controlling the pulse width and current of each LED channel, and includes a wide variety of protection features such as thermal protection and over-voltage protection.
