Logic pin description

7.1

CSEL pin

This input pin allows the setting of two different levels of current. When the voltage on this

pin is low, the internal multiplexer switches the feedback to the FB1 pin, which is the

dedicated feedback pin for low current operation. When the voltage on the CSEL pin is high,

the internal multiplexer switches the feedback to the FB2s pin, and enables the shorting

transistor connected between the FB1 and FB2 pins. The feedback voltage is sensed

current operation.

7.2

FAULT pin

When the STCF07 is in ON mode (EN is high), the device is able to detect disconnection or

failure of the LED. This information can be used by the system to signal that a problem has

occurred in the LEDs.

7.3

ENABLE pin

This pin functions as an enable input. No internal pull-up or pull-down is provided.
