Gate Drivers ICs

TC4423COE Description

The TC4423COE from Microchip Technology is a high-performance, dual-channel low-side gate driver IC designed for robust switching applications. Packaged in a 16-SOIC surface-mount form factor, it operates over a 4.5V to 18V supply range, making it versatile for various power electronics designs. With a peak output current of 3A (source/sink), it efficiently drives MOSFETs and IGBTs, ensuring fast switching with typical rise/fall times of 23ns and 25ns, respectively. The device features inverting inputs and independent channels, providing flexibility in system integration. Its wide operating temperature range (0°C to 150°C TJ) and RoHS3 compliance make it suitable for demanding industrial environments.

TC4423COE Features

• Dual-Channel Design: Two independent drivers for enhanced system flexibility.
• High Current Output: 3A source/sink capability for driving large capacitive loads.
• Fast Switching: 23ns rise and 25ns fall times minimize power losses.
