Diodes Incorporated · LED Drivers · MSOP-8-EP

AL5817MP-13 from Diodes Incorporated, in a MSOP-8-EP. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VCC power_in Supply input, operating range 4.5V to 60V relative to GND.
2 REF power_out Internal reference voltage output (0.4V typ); maximum recommended output current 50µA and capacitance to GND below 100pF, used with a divider to VSET to set LED current.
3 VSET input LED current setting threshold that sets the FB reference voltage (0 to 0.6V); pulled down internally if floating, recommended capacitance to GND below 1nF.
4 GND power_in Ground.
5 FB input Feedback input regulated to the level set by VSET in linear mode; pulled up internally if floating, optional capacitor to GND limited to 100pF or less.
6 OUT output Driving output for the external BJT or MOSFET, up to 15mA, 0 to 4V range.
7 ENB input Chip enable: an input voltage above 2V disables the device and external transistor drive; usable for low frequency PWM dimming.
8 VFAULT input LED-open detection input: if brought below approximately 2.5V the output turns off and auto-retries; open collector/drain PWM signal on this pin enables PWM dimming.
9 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
