KTD2037EWE-TR Description

Short technical summary and product information.

The KTD2037EWE-TR is a fully programmable, constant current RGB LED driver designed for applications such as RGB indicator LEDs in mobile phones and digital cameras. It features an I2C compatible interface for programming LED settings, allowing individual channel control for on/off state and current level.

 

This device provides three independent constant current sinks without external components. It offers 191 current levels per channel, ranging from 0.125mA to 24mA with a step of 0.125mA, and ±5% current matching at maximum current. The driver supports features like On/Off Interval Time Control, Dimming Up/Down Time, and RGB LED Color Control, enabling unique color lighting patterns.

 

Key electrical specifications include an input voltage range of 2.7V to 5.5V and a low shutdown current of 0.1μA. The operating temperature range is -40°C to +85°C. The KTD2037EWE-TR is available in a compact 8-pin UTDFN package measuring 1.5x1.5mm, suitable for surface mounting.

 

An AutoBlinQ mode is included for LED1, which automatically turns the LED on and off every 2 seconds at 8mA after the EN pin goes high. This can be used to notify users of charging status on devices with discharged batteries. The device is Pb-free and RoHS compliant.
