onsemi · LED Drivers · SOIC-16

CAV4109V-GT2 from onsemi, in a SOIC-16. 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 PGND power_in Power ground reference pin that must be connected to the GND pin and to the ground plane on the PCB.
2 GND power_in Ground reference pin for the entire device that must be connected to the ground plane on the PCB.
3 PWM3 input PWM control input for LED3; high turns the channel on if OE is high, low turns it off, and the pin must not be left open.
4 PWM2 input PWM control input for LED2; high turns the channel on if OE is high, low turns it off, and the pin must not be left open.
5 PWM1 input PWM control input for LED1; high turns the channel on if OE is high, low turns it off, and the pin must not be left open.
6 RSET3 passive LED current set pin for LED3; the current pulled out of this pin is mirrored in the LED3 channel with a gain of 400 (regulated to 1.2 V).
7 RSET2 passive LED current set pin for LED2; the current pulled out of this pin is mirrored in the LED2 channel with a gain of 400 (regulated to 1.2 V).
8 RSET1 passive LED current set pin for LED1; the current pulled out of this pin is mirrored in the LED1 channel with a gain of 400 (regulated to 1.2 V).
9 LED3 passive LED channel 3 cathode current-sink terminal, needing more than 0.4 V to operate correctly and withstanding up to 25 V.
10 LED2 passive LED channel 2 cathode current-sink terminal, needing more than 0.4 V to operate correctly and withstanding up to 25 V.
11 LED1 passive LED channel 1 cathode current-sink terminal, needing more than 0.4 V to operate correctly and withstanding up to 25 V.
12 NC unconnected Not connected inside package.
13 NC unconnected Not connected inside package.
14 NC unconnected Not connected inside package.
15 OE input Output enable input; when low all LED channels are off and the device enters shutdown if low longer than tPWRDWN (4 to 8 ms).
16 VDD power_in Positive supply pin for the entire device (3.0 V to 5.5 V), with a 1 µF ceramic bypass capacitor recommended to ground.
