ADUM4221-1BRIZ-RL

Analog Devices · Gate Drive ICs · SOIC-16

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.
