DESCRIPTION
A pull-down current output for external P-channel fault disconnect switch.
Input supply voltage for IC. Connect a 0.1μF decoupling capacitor close to this pin.
IC enable pin. Pull high to enable the IC. If EN is low for longer than 30.5ms, IC will be disabled.
Internal 5V regulator. Connect a 1μF decoupling capacitor on VDC.
PWM input pin for direct PWM dimming control.
/FLAG is latched low under any fault condition and resets after input power is recycled or part is re-enabled. This
pin is an open drain that needs pull-up.
