Fault disconnect switch
Input voltage for the device and LED power
Dual Functions: Enable pin and PWM brightness control pin or DPST control
input. The device needs 4ms for initial power-up Enable, then this pin can
be applied with a PWM signal with off time no longer than 28ms.
De-couple capacitor for internally generated supply rail.
Mode select pin 1
When SEL1 is high, this pin is configured as the SMBus/I
input/output.
When SEL1 is low or floating, this pin is configured as the fault flag output
and will be pulled low when a fault condition occurs. An external pull-up is
required.
When SEL1 is high, this pin is configured as the SMBus/I
input.
When SEL1 is low or floating, this pins is configured as mode select pin 2,
and operates in conjunction with SEL1 to determine the operating mode.
See Table 1 for details.
