7 / 12 page High-Voltage, 3-Channel Linear High-Brightness LED Driver with Open LED Detection _______________________________________________________________________________________ 7 Pulse-Dimming Inputs (DIM_) The MAX16823 features pulsed or chopped-current dimming inputs (DIM_) to chop the LED current and to adjust the brightness. DIM_ also serves as an active- high enable input. A logic-low at DIM_ turns off OUT_ and a logic-high turns on OUT_. If the signal at DIM stays low more than the programmed LEDGOOD delay time, LEDGOOD goes low (Figure 1). Two Brightness Levels for TAIL/STOP Lights Figure 2 shows the PWM dimming operation for the MAX16823 with an ICM7555 timer. The ICM7555 pro- vides an adjustable duty cycle using two external resis- tors and a capacitor. In TAIL operation, the output of the ICM7555 feeds into DIM and lights up the LEDs. The LED’s brightness depends on the duty cycle of the I_REG MAX16823 I_REG I_REG IN IN IN OUT1 CS1 OUT2 OUT3 UVLO THERMAL SHUTDOWN LGC LEDGGOOD DIM3 DIM2 DIM1 GND IN IN IN BANDGAP LEDGOOD DETECTOR CS2 CS3 REG Block Diagram |
