LED1202JR

Overview

The LED1202JR is a 12-channel low quiescent current LED driver IC manufactured by STMicroelectronics. It utilizes a boost topology to drive LEDs with an output current of 20 mA per channel. The device operates within a supply voltage range of 2.6 V to 5 V and features a working frequency of 400 kHz, with a maximum output voltage of 5 V. It is housed in a flip-chip-20 package and supports an operating temperature range from -40 °C to +85 °C.

Feature Summary

Enables smoother and more natural interactions for smart-home devices through patented features that prevent distracting artifacts in color-chasing or deep breathing LED animation effects.
Supports independent adjustment of output current for each channel via 8-bit analog dimming control up to 20 mA per channel and 12-bit internal PWM dimming control.
Allows a single unit to drive four RGB LEDs running up to eight programmable patterns and stored sequences.
Features an innovative synchronization capability that allows connecting up to eight drivers to control larger LED arrays.

Applications

Smart-home devices
Wearable electronics
Small appliances

Procurement Notes

Verify the specific suffix 'JR' corresponds to the Flip-Chip-20 package configuration when sourcing. Confirm RoHS compliance status as indicated in official documentation. Ensure the selected variant matches the required operating temperature range of -40 °C to +85 °C for your application environment.

Selection Notes

Select this component for designs requiring precise multi-channel LED control with minimal external components. The integrated boost regulator simplifies circuit design for series LED configurations. Consider the 12-channel capacity for driving multiple RGB units without additional multiplexing hardware.

Part Context

This part belongs to the LED1202 series of LED illumination driver ICs. It is designed for energy-efficient DC/DC powered applications. The series includes variants like the LED1202QTR, which shares similar electrical characteristics but differs in packaging.
