MITSUBISHI LINEAR ICs M51901P 12-POINT/23-MODE LED DRIVER DESCRIPTION The M51901 P is a semiconductor integrated circuit consisting of a driver circuit capable of driving 12 LEOs in 23 modes. When a DC voltage is applied to the input pin the. LEO driving outputs are activated either 1 or 2 at a time to provide 23 LEO drive modes in accordance with the applied voltage level. In addition, a blanking function is available when the reference voltage is made a low level. The M51901P consists of 12 differential amplifiers and the associated ladder circuit as well as a blanking circuit. FEATURES • 12 LEOs may be driven in accordance with the level of a DC voltage applied to the input, using a built-in A-O conversion capability.
