Mingjiada Electronics Supply TI TCA6507RUER Low Voltage 7-Bit I²C And SMBus LED Driver IC

[Shenzhen Mingjiada Electronics Co., Ltd.] Supplies the Texas Instruments (TI) TCA6507RUER, a high-performance low-voltage 7-bit I²C and SMBus LED driver designed for modern electronic equipment requiring precise LED control. By integrating robust control functions, this TCA6507RUER chip significantly reduces the microprocessor's burden in LED management, providing an efficient solution for consumer electronics, automotive electronics, and industrial equipment.

Product Description Details
The TCA6507RUER is a 7-channel LED dimmer for two-wire bidirectional bus (I²C), designed to control (or dim) LEDs via the I²C interface. Without this device, the microcontroller must be actively involved in turning on and off the LEDs (per the required dimming rate), which uses valuable processor time. The TCA6507RUER alleviates this issue by limiting the number of operations required by the processor in blinking LEDs and helps to create a more efficient system.
Output Drive Capability: This device provides seven open-drain outputs capable of directly driving LEDs, with a maximum output current of 40mA per channel.
Control Interface: The TCA6507RUER is programmed via an I²C bus interface and is SMBus-compatible. It handles all internal PWM logic, allowing the processor to allocate resources to more critical tasks.
Package: The TCA6507RUER utilises a compact 12-pin X2QFN package (dimensions 2.0mm x 1.4mm), suitable for space-constrained applications.

TCA6507RUER Specifications:
Supply Voltage: 1.65V to 3.6V
Output Voltage: 5.5V

Product Features
Extensive LED Effect Control: The TCA6507RUER supports LED on/off, flashing, and programmable fade-in/fade-out effects, enabling smooth visual transitions.
Independent Dual Memory Regions: The device incorporates two independent LED driver groups, allowing separate control of two LED sets for enhanced design flexibility.
Precise Intensity Control: The TCA6507RUER offers 16-level maximum intensity control, enabling precise adjustment of LED brightness from fully off to fully on.
High-Reliability Design: The TCA6507RUER incorporates robust ESD protection with latch-up performance exceeding 100mA, ensuring reliability and durability in demanding environments.
Low power consumption and high tolerance: The device features low standby current and a shutdown function, contributing to system energy efficiency. Its open-drain output can withstand 5.5V voltage, permitting direct connection to higher-voltage LEDs or other loads.

Application Areas
Consumer Electronics: The TCA6507RUER is ideally suited for LED status indicators, keyboard backlighting and decorative lighting in smartphones, tablets and wearable devices, where its rich effects enhance the user experience.
Automotive Electronics: Within automotive instrument clusters, centre console button backlighting, and interior ambient lighting systems, the TCA6507RUER's wide operating temperature range (-40°C to +125°C) and reliable performance meet the demands of automotive applications.
Industrial Control: For indicator lights, alarm indicators, and equipment status displays in industrial control panels, the TCA6507RUER adapts to the wide temperature range of industrial environments while ensuring stable operation.
Home Appliances and IoT Devices: In display panels for household appliances (such as smart speakers and washing machines) and IoT end devices, the TCA6507RUER's low-power characteristics help extend battery life while providing essential LED status indications and dynamic effects.

In summary, the TCA6507RUER represents a comprehensive, reliable LED driver solution. Its flexible control methods and compact packaging design make it an ideal choice for numerous electronic products.
