IS31FL3235-QFLS2-TR is a LED driver integrated circuit (IC). It is a Type-3 LED driver family consisting of a Smart Matrix Keypad controller and sixteen scan LED Drivers. It is a “keypad plus LED” driver and is ideal for use in any product that requires a key operates and LED indications.This IC works on the principle of Pulse Width Modulation (PWM). The PWM is used to control the quantity of electric power that is delivered to the LEDs. It enables a dimming control over the brightness of the LEDs.

The IS31FL3235-QFLS2-TR offers 16 scan outputs providing up to 4 current levels per channel per scan and the output of this IC can be adjusted to 32 brightness levels for each individual LED by the user.The driver comprises two independent bidirectional ports, a serial (S0.S1) port and an I2C port control. This makes it easier to control sixteen LEDs through a serial port and also to share the same port with other peripheral devices. This IC offers excellent scanning capabilities to create smooth, fade-in and fade-out effects.

The IS31FL3235-QFLS2-TR is a high efficiency device, with a typical operating voltage of 1.8V to 5.5V and a power draw of 200 µA in active mode. It has a light sensing feature to automatically adjust the brightness of the LEDs according to the ambient light conditions. It is also capable of detecting incoming light and can respond with various levels of dimming to achieve the desired lighting effect. The IS31FL3235-QFLS2-TR is particularly suitable for applications like consumer electronic products such as smartphones, tablets, remote controllers, gaming controllers, and wearable electronic products.

In addition it is widely used in automotive electronics such as lighting controls, backlit LCDs, vehicle multimedia systems and navigation systems. This IC is also highly suitable for industrial LED lighting applications such as LED strip lighting and LED panel lighting. You can also use it for other LED applications such as LED lighting for indoor or outdoor displays, LED message boards and LED signs.

The IS31FL3235-QFLS2-TR is a feature-rich LED driver IC and is an ideal solution for an array of LED lighting applications. It is capable of providing efficient and smooth dimming control, accurate brightness control and excellent scanning capabilities with up to 32 brightness levels per LED. As a result, it is widely used in both automotive and consumer electronic applications, as well as many industrial lighting systems.
