AL3022MTR-G1

Diodes Incorporated · LED Drivers · SO-8

AL3022MTR-G1 from Diodes Incorporated, in a SO-8. 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 VIN power_in Supply input pin; a capacitor between VIN and GND keeps the DC input voltage constant, with VIN recommended operating range 4 V to 18 V and absolute maximum -0.3 to 20 V.
2 OUT output Gate driver pin connected to the external MOSFET gate to turn it on and off, with OUT pin voltage rated at 20 V maximum.
3 GND power_in Ground pin.
4 CS input Over-current protection pin connected to the current-sense resistor; if the CS voltage exceeds 0.33 V (typical threshold), the output is turned off immediately until the next cycle begins.
5 FB input Feedback pin connected to an external resistor divider that programs the system output voltage; the feedback voltage is 0.2 V typical (0.194 V to 0.206 V), with FB pin voltage absolute maximum -0.3 to +5.5 V.
6 COMP output Compensation pin, the output of the internal error amplifier, which is forced to low when VIN is below 3.6 V.
7 OVP input Overvoltage detection pin; the controller latches off the output when the OVP pin senses more than 1.55 V (typical), and MOSFET drive turns off if OVP is below 0.1 V to protect against VOUT short to GND.
8 EN input Enable and dimming pin; the IC is disabled below 0.3 V and enabled above 2.6 V, supports PWM dimming with an external signal above 100 Hz at 1% to 90% duty cycle, and supports analog dimming with a DC signal from 0.8 V to 2.4 V.
