Applications
The TC4425AVOA is used in synchronous buck and boost converters, half-bridge and H-bridge motor drives, and DC-DC converter circuits where fast, high-current gate drive is needed to switch power MOSFETs at 100 kHz to 1 MHz frequencies. It is also applied in solenoid drivers, relay coil excitation circuits, and class-D audio amplifier output stages that require a robust buffer with Schmitt trigger noise immunity on the input. The dual-channel configuration in a single SOIC-8 package reduces PCB component count in multi-switch power stages.

Frequently Asked Questions
What peak gate drive current can TC4425AVOA deliver to switch a power MOSFET with 20 nC gate charge?
TC4425AVOA provides up to 1.5 A peak output current per channel, which can charge a 20 nC gate in approximately 13 ns, enabling switching rise times well under 50 ns at 12 V gate drive voltage in typical synchronous buck converter designs.
How does the Schmitt trigger input of TC4425AVOA help in PWM gate drive applications with long signal traces?
The Schmitt trigger input adds typically 0.5 V to 1 V of hysteresis on the input threshold, preventing false switching from ground bounce or capacitive coupling noise on PWM signal traces exceeding 10 cm in length between the controller IC and the gate driver.
What supply voltage range makes TC4425AVOA compatible with both 5 V logic-level and 12 V gate-drive bus systems?
The driver operates from 4.5 V to 18 V, spanning the standard 5 V and 12 V gate-drive bus voltages used in consumer and industrial power supplies, and supports the 15 V gate-drive level preferred for fully enhancing silicon IGBTs in motor-control inverters.
For procurement teams evaluating TC4425AVOA, what lead time and RoHS status apply?
Factory lead time is 6 weeks, and the part carries a Pb-free code of 'Yes' with JESD-609 code e3, confirming RoHS-compliant lead-free solder compatibility. The SOIC-8 package ships on standard 12-inch tape-and-reel, simplifying automated SMT kitting for production builds.
