What are the key features of TC4425AVMF?
- Dual 3 A peak source and sink gate drive current enables fast MOSFET switching transitions to minimize switching losses in DC/DC converters
- Schmitt-trigger inputs with hysteresis reject noise and slow edges from PWM controllers, preventing false triggering in noisy switching environments
- DFN-S-8 (small-outline no-lead) package with exposed pad improves thermal dissipation and reduces PCB footprint versus SOIC alternatives
What is TC4425AVMF used for?
TC4425AVMF is used to drive the gate of power MOSFETs in synchronous buck converters, half-bridge inverters, and brushed DC motor controllers where fast 3 A gate charging is needed to reduce MOSFET turn-on and turn-off times below 10 ns. Its dual-channel design allows one IC to drive both high-side and low-side switches in a half-bridge topology without a separate bootstrap driver. The Schmitt-trigger inputs make it robust in electrically noisy industrial and automotive power stages.

Frequently Asked Questions
What peak gate drive current does TC4425AVMF deliver and how does it reduce MOSFET switching losses?
TC4425AVMF delivers 3 A peak source and sink gate drive current, allowing it to charge and discharge a 10 nC gate charge MOSFET in approximately 3 ns. Faster gate transitions reduce the MOSFET's overlap time between high drain voltage and high drain current during switching, cutting switching losses by up to 50 % compared to a 1 A driver in a 500 kHz DC/DC converter.
How does the Schmitt-trigger input of TC4425AVMF protect the circuit from PWM noise glitches?
The Schmitt-trigger inputs of TC4425AVMF provide built-in input hysteresis, typically around 0.5 V, so the driver ignores noise spikes and slow ringing edges from the PWM controller output without external RC filtering. This prevents false gate pulses that could cause shoot-through in half-bridge topologies, improving reliability in motor drives and inverters with noisy ground planes.
Can TC4425AVMF drive both high-side and low-side MOSFETs in a synchronous buck converter?
Yes. TC4425AVMF has 2 independent channels, each rated at 3 A peak, allowing one device to drive both the high-side and low-side N-channel MOSFETs in a non-isolated synchronous buck converter. The buffer/inverter topology means one channel inverts the PWM signal for the complementary switch, simplifying gate drive logic and reducing the external component count by eliminating a separate low-side driver IC.
What are the package and procurement details for TC4425AVMF in a production design?
TC4425AVMF comes in a DFN-S-8 (R-PDSO-N8) surface-mount package, which is lead-free (JESD-609 e3) and RoHS compliant, with an 8-year YTEOL indicating continued production availability. Factory lead time is approximately 13 weeks, so placing a blanket purchase order with buffer stock is recommended for high-volume designs to avoid supply gaps in power management sub-assemblies.
