As companies integrate more features with LED status into their battery-operated products; long battery life has become an important design factor. Many IoT devices and wearables use primary batteries which are not rechargeable. For such products, improving the battery life by minimizing power consumption is a key differentiator and an important selling feature. Therefore, to ensure efficient and long battery life, circuits must support ultra-low power consumption. To address this low power market segment, Lumissil recently introduced four LED matrix drivers incorporating ultra-low power consumption and other advanced features. The new IS31FL3751/2/6 and IS31FL3242 drivers require less than 500µA (or 0.5mA) of operating current, 0.5uA (or 0.0005mA) of shutdown current, and support 12-bit PWM with dot correction; all in a small IC footprint.
