ADUM4221-1ARIZ

Analog Devices · Gate Drive ICs · SOIC-16

ADUM4221-1ARIZ 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 PWM logic input for the ADuM4221-1 that sets the half-bridge output state, with the logic input rated up to 6.5 V when VDD1 is unpowered.
2 NC unconnected No connect pin; do not connect to this pin.
3 VDD1 power_in Input supply voltage, specified at 2.5 V to 6.5 V referenced to GND1; pins 3 and 8 are internally connected and connecting both is recommended.
4 GND1 power_in Ground reference for the input logic signals.
5 DISABLE input Input disable pin that disables the isolator inputs and refresh circuits when driven high.
6 DT input Dead time control input; the resistor from DT to ground sets the dead time, with a recommended resistor range of 10 kΩ to 500 kΩ.
7 NC unconnected No connect pin; do not connect to this pin.
8 VDD1 power_in Input supply voltage, specified at 2.5 V to 6.5 V referenced to GND1; internally connected to pin 3 and connecting both is recommended.
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, specified at 4.5 V to 35 V referenced to GNDB.
12 NC unconnected No connect pin; do not connect to this pin.
13 NC unconnected No connect pin; 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, specified at 4.5 V to 35 V referenced to GNDA.
