Description
The FAN5610 generates matched current source drives for a
maximum of four LEDs. Since each LED current source has
its own self-regulating loop, precise current matching is
maintained even if there is a substantial forward voltage
spread among the LEDs. LED pre-selection therefore is not
required. In order to minimize voltage drop, and maximize
efficiency, the value of the internal current sense resistors
connected in series with the LEDs is very low (10
an important consideration for direct DC-driven white LEDs
in battery-powered systems.
). This is
The LEDs’ current can be set to 0mA (OFF Mode), 7mA,
14mA, and 21mA with a built-in two-bit digital-to-analog
converter. Customized current settings can also be used.
When the control bits are set to zero, the internal circuitry is
disabled and the quiescent current drops below 1μA.
Both digital input lines (A, B) can be pulse-width-modulated
(PWM).
Using PWM, any value of average LED current can
be obtained within the 1 to 20 mA range. The FAN5610 is
available in an 8-lead 3X3 MLP package.
