MITSUBISHI MITSUBISHI 〈DIGITAL 〈DIGITAL ASSP ASSP 〉 〉 M66503ASP/AGP M66503ASP/AGP 16-BIT CONSTANT CURRENT LED DRIVER with SHIFT REGISTER AND LATCH 16-BIT CONSTANT CURRENT LED DRIVER with SHIFT REGISTER AND LATCH DESCRIPTION The M66503A is a constant current LED driver IC, whose output current is variable. The IC’s functions include 16-bit serial input/parallel output shift register with output latch. The product uses Bi-CMOS process for highly accurate constant current driving, permitting high-efficiency LED driving without using a resistor that limits LED current. Settings for the LED drive current are made by an external resister, thereby ensuring a maximum output current of 30 mA, enough for anode-common LED driving. Furthermore, the pin configuration of the IC permits easier wiring on a printed board. FEATURES Anode-common LED driving Constant current output: Set to a value within a range between 0 and 30mA with an external resistor only. Simultaneous lighting available. Pins (OEA, OEB) provided for forced ON/OFF of LED drive current. Greater noise margin: Total-input Schmitt circuit is employed to deal with longer wire lengths. Input/output CMOS compatible Serial data output provided (SQ15) 5V single power supply Pin configuration for easier wiring on printed board APPLICATION LED array drivers for display panel and printer. Other various LED modules. FUNCTION The M66503A is a constant current LED driver for anodecommon LEDs. To set the LED driving curr...
