L6924D013TR

Another key benefit of the L6924D is its programmability. Users have the ability to adjust various charging parameters, such as pre-charge current, fast-charge current, voltage thresholds, and charge timer settings. The device also features two open collector outputs for diagnostic purposes, allowing for easy integration with external indicator LEDs or communication with a host microcontroller
