LED Drivers

We offer LED constant current driver controllers for control of keypad LEDs, fun lighting and status LEDs.

The LED constant current drivers off-load host processor with internal PWM dimming or blinking control including sequences like heart beat/breathing status indication. These LED drivers have I²C-Bus or SPI interfaces and are used for applications such as: RGB or RGBA LED, LED status information, LED displays, LCD backlights, keypad backlights for cellular phones or handheld devices.

Several are AEC-Q100 compliant (PCA9952/55TW and PCA9955BTW) for applications like Steering Wheel LED status indication.
