Table 2. Atmel LED Driver-MSL3082 Timing and LED Intensity Control Capability
LED INTENSITY CONTROL RESOLUTION
LED string current External resistors set maximum current for each LED string up to at least 500mA
Individual LED string current 6-bit ISTR registers reduce string current from maximum set by global resistor
Global LED string pulse width 6-bit GINT register or PWM input (accepts 20Hz To 50kHz, 0% to 100% duty cycle)
Individual LED string pulse width 8-bit PWM registers set individual string pulse width
Global temperature derating 6-bit temperature pulse width derating, individually applied to each string
Total LED string pulse width control 10-bit LED string pulse width, computed from global and individual pulse width settings
