Gate Drivers ICs

TC4429CPA Description

The TC4429CPA from Microchip Technology is a high-performance, low-side gate driver IC designed for robust switching applications. Housed in an 8-pin DIP (Through Hole) package, it offers a 4.5V to 18V supply voltage range, making it versatile for various power electronics designs. With a peak output current of 6A (source/sink), it efficiently drives MOSFETs and IGBTs, ensuring fast switching with 25ns rise/fall times. The device operates over a wide temperature range (0°C to 150°C junction temperature) and features an inverting input logic, compatible with TTL and CMOS levels (VIL = 0.8V, VIH = 2.4V). Its single-channel, non-inverting output simplifies integration into systems requiring precise gate control.
