The MSL3086-IU is a Polymer Multi-Channel LED-Driver IC designed for driving a variety of light-emitting diodes used for general lighting applications, such as automotive and industrial lighting. This IC features a low-profile package and offers design flexibility in terms of switching frequency and current levels for different types of LED configurations. The MSL3086-IU belongs to the category of PMIC - LED Drivers.

MSL3086-IU is a robust IC suitable for current modes (constant current and pulsed current) LED lighting control. It provides a wide range of current options, from 10mA to the maximum PWM LED current of 50mA. The MSL3086-IU also supports up to 4-channel LED control with a wide array of brightness control methods, such as PWM or analog voltage control.

The MSL3086-IU integrates the constant-current regulator, the drive circuitry for current control, a temperature monitor, among other peripherals. The constant-current output is controlled by either a switching-mode PWM signal from an external source or an analog voltage applied to the current regulate pin (CR). The switching-mode PWM frequency is adjustable with a resistor, while the analog voltage is programmed with a voltage divider.

The MSL3086-IU provides protection features such as undervoltage lock-out (UVLO) and thermal shutdown (TSD). The UVLO prevents the device from operating outside its voltage ratings. The TSD prevents the device from being damaged due to excessive junction temperature. The MSL3086-IU also includes a lockup latch circuit that is activated when the junction temperature reaches the critical point, which can be useful for long on-time LED operation.

The MSL3086-IU is packaged in a 10-pin MSOP package and operates at supply voltages from 5V to 18V. It can provide a maximum output current of up to 50mA per channel and is compatible with various types of PWM and analog inputs. The MSL3086-IU is suitable for low-power LED lighting applications due to its integrated functions and features.

In conclusion, the MSL3086-IU is a PMIC - LED driver designed for driving a variety of light-emitting diodes used for general lighting applications. It integrates a constant-current regulator, LED driver circuitry, temperature monitor, undervoltage lock-out and thermal shutdown, among other peripherals. Its maximum output current is up to 50mA per channel and it can be used with either switching-mode PWM or analog voltage control. The MSL3086-IU is packaged in a 10-pin MSOP package and is suitable for low-power LED lighting applications.
