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