Arc Fault-Detection Input. When the peak voltage on OLF rises above the internal threshold of 1.2V (typ), an
internal current source starts charging the TFLT capacitor. The MAX8785A sets the fault latch and disables the
gate drivers after the TFLT voltage reaches 3V. For details, see Setting the Arc Protection Threshold section.
Brightness Control Select Input. Brightness can be adjusted with an analog voltage on CNTL or with an
external signal at LSYNC. Connect SEL to GND to enable analog control. Connect SEL to V
external synchronization control.
5.35V/20mA Linear-Regulator Output. Supply voltage for the device. Bypass V
capacitor to GND.
System Ground
Supply Input. Input to the internal 5.35V linear regulator that powers the device. Bypass BATT to ground
with a 0.22μF ceramic capacitor.
Backside Exposed Pad. PAD is internally connected to GND. Connect the exposed pad to a ground plane
through a thermally enhanced via.
