The S6AL211A94MV20000 is a PMIC - LED Drivers that is widely used in varieties of applications.

The product is a high-efficiency current driver for multi-LED white backlight, featuring low power dissipation. It includes on-chip multiple current adjustment registers and built-in remote sensing capability, which provides versatile functions and a high level of current accuracy. The S6AL211A94MV20000 also features a low operating current. In order for the product to reach its full performance potential, users should pay attention to properly manage thermal by using the heatsink.

The device operates at 8V to 15V or 8V to 17V, depending on the application. It has comprehensive protection features including LED over current protection, line over voltage protection, input under voltage protection and output short circuit protection. The S6AL211A94MV20000 has also an adjustable average output current to provide excellent dimming range of 40% to max current.

The S6AL211A94MV20000 works based on the concept that LEDs can be driven by a constant current. To achieve that, the device regulates the output current against the changing forward LED voltage. The LED current is regulated via a reference voltage set by a voltage divider made of external resistor, and the LED output current does not vary, even when the output voltage varies over a wide range.

The device uses two types of input pins. The first one is the PVM pin, which receives the reference voltage from the voltage divider to provide a precise output current regulation. The second pin is the EN pin that is used for external control of the device. It will directly shut the module off once a low voltage is applied on the EN pin.

In order to control the output current, the S6AL211A94MV20000 employs a current control register(CCR), which allows eight steps of current adjustment. The CCR is programmable and allows users to adjust the output current by controlling the output voltage. It also provides additional features such as remote sensing capability, which enables users to adjust the current voltage to compensate the voltage drop due to long cable length.

The S6AL211A94MV20000 is an ideal solution for driving LEDs with low power dissipation and comprehensive regulatory features. It is an ideal choice for applications like displays backlighting, indicator lighting, automotive, and industrial lighting. This device also features a wide operating temperature range from -40°C to 125°C, making it highly reliable for industrial applications.
