Frequently Asked Questions
How much peak gate drive current can the TC4420EOA deliver to a power MOSFET?
The TC4420EOA delivers up to 6 A peak output current, enabling very fast charge and discharge of large MOSFET gate capacitances. This reduces switching transition times, lowering switching losses in high-frequency power conversion stages operating above 100 kHz.
Does the TC4420EOA support high-side MOSFET driving in a bootstrap topology?
Yes, the TC4420EOA is specifically a high-side driver with a Schmitt-trigger input interface, making it compatible with bootstrap gate drive topologies. Its 6 A output and inverting buffer architecture allow direct connection to PWM controllers driving N-channel MOSFETs in half-bridge or full-bridge converter designs.
What package and pin count does the TC4420EOA come in?
The TC4420EOA comes in an 8-pin SOIC (R-PDSO-G8) package, a widely available small-outline form factor with 1.27 mm pin pitch. This compact package fits easily on standard PCBs alongside gate resistors and bootstrap capacitors without requiring a large board area.
In which industrial power applications is the TC4420EOA a strong fit?
The TC4420EOA suits switch-mode power supplies, synchronous buck and boost converters, DC motor drives, and solenoid actuators. Its 6 A drive strength and Schmitt-trigger input make it reliable in noisy environments with switching frequencies up to several hundred kHz, covering a broad range of industrial power electronics designs.
