PRODUCTION DATA.
PIN | TYPE(1) | DESCRIPTION | |
---|---|---|---|
NAME | NO. | ||
ADDR | 20 | I | I2C slave-address selection pin. See I2C Slave Addressing for more details. This pin must not be left floating. |
AGND | 4 | G | Analog and digital ground. Connect to PGND, exposed thermal pad, and common ground plane. |
C1– | 24 | A | Negative pin of charge-pump flying capacitor 1. If charge pump is not used, this pin must be left floating. |
C1+ | 2 | A | Positive pin of charge-pump flying capacitor 1. If charge pump is not used, this pin must be left floating. |
C2– | 23 | A | Negative pin of charge-pump flying capacitor 2. If charge pump is not used, this pin must be left floating. |
C2+ | 1 | A | Positive pin of charge-pump flying capacitor 2. If charge pump is not used, this pin must be left floating. |
CLK | 6 | I, OD | Clock input/output. By default this pin is a clock input. If not used, this pin must be connected to GND or VIN. |
EN/PWM | 5 | I | Chip enable and PWM input pin. |
GPIO/TRIG/INT | 7 | I, OD | General-purpose input or open-drain output, or trigger input or open-drain output, or interrupt open-drain output. This pin function is configured in the I2C registers. By default this pin is a general-purpose output (open-drain) and can be left floating if not used. |
LED0 | 19 | A | LED current sink 0. If not used, this pin can be left floating. |
LED1 | 18 | A | LED current sink 1. If not used, this pin can be left floating. |
LED2 | 17 | A | LED current sink 2. If not used, this pin can be left floating. |
LED3 | 16 | A | LED current sink 3. If not used, this pin can be left floating. |
LED4 | 15 | A | LED current sink 4. If not used, this pin can be left floating. |
LED5 | 14 | A | LED current sink 5. If not used, this pin can be left floating. |
LED6 | 13 | A | LED current sink 6. If not used, this pin can be left floating. |
LED7 | 12 | A | LED current sink 7. If not used, this pin can be left floating. |
LED8 | 11 | A | LED current sink 8. If not used, this pin can be left floating. |
PGND | 21 | G | Charge-pump power ground. Connect to AGND, exposed thermal pad, and common ground plane. |
SCL | 9 | I | I2C bus clock line. If not used, this pin must be connected to GND or VIN. |
SDA | 8 | I, OD | I2C bus data line. If not used, this pin must be connected to GND or VIN. |
V1P8 | 10 | P | Input power for digital circuitry. |
VIN | 3 | P | Input power, a 1-µF capacitor must be connected between PGND and this pin. |
VOUT | 22 | A | Charge-pump output voltage. If charge pump is used, a 1-µF capacitor must be connected between PGND and this pin. If charge pump is not used or is used in 1× mode only, the capacitor can be omitted. |
Exposed thermal pad | — | — | Must be connected to AGND (pin 4), PGND (pin 21), and common ground plane. See Layout Example. Must be soldered to achieve appropriate power dissipation and mechanical reliability. |
