ADUM4221-1BRIZ-RL from Analog Devices, 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 | PWM | input | Logic input for the PWM control of the ADuM4221-1; sets the dead-time-controlled outputs. |
| 2 | NC | unconnected | No connect; do not connect to this pin. |
| 3 | VDD1 | power_in | Input supply voltage, 2.5 V to 6.5 V referenced to GND1; pin 3 and pin 8 are internally connected and both should be connected to the VDD1 supply. |
| 4 | GND1 | power_in | Ground reference for input logic signals. |
| 5 | DISABLE | input | Input disable; a high level disables the isolator inputs and refresh circuits. |
| 6 | DT | input | Dead time control input; the resistor connected from DT to ground sets the dead time, with a resistor range of 10 kΩ to 500 kΩ. |
| 7 | NC | unconnected | No connect; do not connect to this pin. |
| 8 | VDD1 | power_in | Input supply voltage, 2.5 V to 6.5 V referenced to GND1; internally connected to pin 3. |
| 9 | GNDB | power_in | Ground reference for output B. |
| 10 | VOB | output | Inverting output B of the half bridge driver. |
| 11 | VDDB | power_in | Output B supply voltage, 4.5 V to 35 V referenced to GNDB; grade B UVLO positive-going threshold is 7.5 V maximum. |
| 12 | NC | unconnected | No connect; do not connect to this pin. |
| 13 | NC | unconnected | No connect; do not connect to this pin. |
| 14 | GNDA | power_in | Ground reference for output A. |
| 15 | VOA | output | Noninverting output A of the half bridge driver. |
| 16 | VDDA | power_in | Output A supply voltage, 4.5 V to 35 V referenced to GNDA; grade B UVLO positive-going threshold is 7.5 V maximum. |
