View| PIN | I/O | DESCRIPTION | |
|---|---|---|---|
| NAME | NO. | ||
| ADDR | 23 | I | Address detect pin. Resistor value at this pin selects the I2C address. See Section 8.3.1. |
| AVDD | 24 | P | Analog power input. Connect to 1.8-V supply and decouple to GND with a capacitor. |
| BST_N | 30 | P | Class-D negative bootstrap. Connect a capacitor between BST_N and OUT_N. |
| BST_P | 4 | P | Class-D positive bootstrap. Connect a capacitor between BST_P and OUT_P. |
| BYP_EN | 11 | O | Low voltage signaling pin with open drain output. It can be used to enable/disable an external DC-DC converter. |
| DGND | 25 | P | Device substrate ground. Connect to PCB ground plane. Avoid any common routing inductance between this pin and GND pin. |
| DREG | 10 | P | Digital core voltage regulator output. Bypass to GND with a capacitor. Do not connect to external load. |

| GND | 7 | P | Analog ground. Connect to PCB ground plane. |
| ICC | 6 | IO | Inter-chip communication pin. |
| IOVDD | 20 | P | Digital IO power supply. Connect to an 1.8-V or a 3.3-V supply and decouple with a capacitor to GND. |
| IRQZ | 21 | O | Open drain, active low, interrupt pin. Pull up to IOVDD with resistor if optional internal pull up is not used. |
| NC | 8, 9, 16, 17 | Not Connected. | |
| OUT_N | 29 | O | Class-D negative output. |
| OUT_P | 3 | O | Class-D positive output. |
| PGND | 2 | P | Class-D ground. Connect to PCB ground plane. |
