Vishay Siliconix SI9978DW-T1-E3 is a four-channel, half-bridge gate driver IC designed for efficient power management applications. This non-inverting driver features an N-channel MOSFET gate type and operates with a supply voltage range of 14.5V to 17.5V. The high-side voltage capability reaches up to 40V (bootstrap), facilitating robust operation in demanding environments. Key specifications include typical rise and fall times of 110ns and 50ns respectively, and logic voltage thresholds of 1V (VIL) and 4V (VIH). Packaged in a 24-SOIC (0.295", 7.50mm Width) format, it is supplied on tape and reel. The Vishay Siliconix SI9978DW-T1-E3 is well-suited for use in industrial power supplies, motor control, and automotive electronics where precise and reliable power switching is critical. Its operating temperature range is -40°C to 150°C (TJ).
