IS31FL3193-DLS2-TR from ISSI Integrated Silicon Solution, in a DFN-10-EP(3x3). Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | SDB | input | Shutdown input. Pull low to shut down the chip; pull high (via pull-up, typically 100kΩ) to enable normal operation. |
| 2 | VCC | power_in | Power supply input, 2.7V to 5.5V. Decouple with 1µF and 0.1µF capacitors to GND. |
| 3 | OUT1 | output | Constant-current sink output for LED channel 1. Sinks up to 42mA with 256-step PWM control; current-sink headroom voltage typ. 500mV at 42mA. |
| 4 | OUT2 | output | Constant-current sink output for LED channel 2. Sinks up to 42mA with 256-step PWM control; current-sink headroom voltage typ. 500mV at 42mA. |
| 5 | OUT3 | output | Constant-current sink output for LED channel 3. Sinks up to 42mA with 256-step PWM control; current-sink headroom voltage typ. 500mV at 42mA. |
| 6 | GND | power_in | Ground reference. Thermal pad must also be connected to GND. |
| 7 | AD | input | I2C slave address select input. Tie to GND or VCC to select one of two I2C addresses. |
| 8 | SCL | input | I2C serial clock input, up to 400kHz. Requires external pull-up resistor (typ. 4.7kΩ) to VDD. |
| 9 | SDA | bidirectional | I2C serial data line. Open-drain bidirectional; requires external pull-up resistor (typ. 4.7kΩ) to VDD. |
| 10 | V_BM | output | Breathing mark signal output. Indicates the breathing state of the LED driver. |
| 11 | EP | power_in | Exposed thermal pad on the bottom of the DFN-10 package. Must be connected to GND for proper thermal and electrical operation. |
