DM633 LED Treiber IC für Displays, VMS , Lighting

DM633 is a 16-channel constant current sink LED driver. Each channel has adjustable 12-bits grayscale PWM control current outputs. 7-bit global brightness control is included in supporting user to adjust chip current easily. It incorporates shift registers, data latches, constant current circuitry with current value set by an external resistor, selectale oscillator source for PWM functioning, and built-in LED open/short detection circuit to detect error status. It supports thermal alarm and shutdown function, system retrieve the message to indicate when junction temperature over limitation of chip. It is specifically designed for LED display and lighting applications.
