**Chipanalog** · Digital Isolators · SOIC-6-300mil

CA-IS3211VCJ from Chipanalog, in a SOIC-6-300mil. 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 | ANODE | input | Driver input, the anode of the input LED-equivalent diode. Forward current sourced into ANODE (through a series limiting resistor) turns on the gate driver output. Max avg input current 25 mA; max reverse voltage 7 V. |
| 2 | NC | unconnected | No internal connection. Leave floating or tie to a convenient net; do not use to route signals. |
| 3 | CATHODE | input | Driver input, the cathode of the input LED-equivalent diode. Current returns through this pin from ANODE; typically pulled low (or to logic driver output) to complete the input current loop. |
| 4 | VEE | power_in | Negative power supply input for the output-side; the negative output supply rail. For bipolar operation, bypass VEE to output-side ground with 0.1 μF || 10 μF as close as possible to the device. For single-supply operation, connect VEE to output-side GND. VCC−VEE range: −0.3 V to 32 V absolute max. |
| 5 | VOUT | output | Gate driver output. Rail-to-rail output between VCC and VEE, capable of 6 A peak sink / 5 A peak source. Drives the gate of an external power MOSFET, IGBT or SiC transistor; pulled low when VCC is unpowered, open-circuit, or in UVLO. |
| 6 | VCC | power_in | Positive power supply input for the output-side; the positive output supply rail. Bypass VCC to output-side ground with 0.1 μF || 10 μF as close as possible to the device. VCC−VEE operating range 14 V to 30 V for the 12 V UVLO (VCJ) version. |
