ADUM3223ARZ-RL7

Analog Devices · Isolators - Gate Drivers · SOIC-16

ADUM3223ARZ-RL7 from Analog Devices, in a SOIC-16. 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 VIA input Logic Input A. CMOS logic input (0.7 x VDD1 high, 0.3 x VDD1 low) that drives isolated Output A.
2 VIB input Logic Input B. CMOS logic input that drives isolated Output B.
3 VDD1 power_in Input Supply Voltage (3.0 V to 5.5 V). Pin 3 and Pin 8 are internally connected; connecting both pins to VDD1 is recommended.
4 GND1 power_in Ground Reference for Input Logic Signals.
5 DISABLE input Input Disable. When high, it disables the isolator inputs, setting outputs to a low state. Reaction time is approximately equal to the normal propagation delay.
6 NC unconnected No Connect. Do not connect to this pin.
7 NC unconnected No Connect. Do not connect to this pin.
8 VDD1 power_in Input Supply Voltage (3.0 V to 5.5 V). Internally connected to Pin 3; connecting both pins to VDD1 is recommended.
9 GNDB power_in Ground Reference for Output B (isolated from input GND1).
10 VOB output Output B. Gate driver output, 4 A peak, driven from VDDB. Rail-to-rail CMOS output with typical 1.1 ohm source/0.6 ohm sink pulsed resistance.
11 VDDB power_in Output B Supply Voltage (4.5 V to 18 V). Powers the Output B gate driver stage referenced to GNDB.
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 (isolated from input GND1 and independent from GNDB).
15 VOA output Output A. Gate driver output, 4 A peak, driven from VDDA. Rail-to-rail CMOS output with typical 1.1 ohm source/0.6 ohm sink pulsed resistance.
16 VDDA power_in Output A Supply Voltage (4.5 V to 18 V). Powers the Output A gate driver stage referenced to GNDA.
