The TC4421AVAT from Microchip Technology is an improved single-output MOSFET driver. It is designed to provide high-current buffering for driving large MOSFETs and Insulated Gate Bipolar Transistors (IGBTs). This device offers matched output rise and fall times, as well as matched leading and falling-edge propagation delay times, ensuring consistent performance.
Key electrical specifications include a high peak output current of 10A (typical) and a high continuous output current of 2A (maximum). The operating supply voltage range is wide, from 4.5V to 18V. Matched fast rise and fall times are achieved, with 15 ns for a 4,700 pF load and 135 ns for a 47,000 pF load. Propagation delays are typically 42 ns.
The TC4421AVAT features low shoot-through/cross-conduction current in its output stage, which reduces overall power dissipation. It is latch-up protected and can withstand 1.5A of output reverse current. The input can withstand negative inputs up to 5V and includes 300 mV of hysteresis for noise immunity.
Available in space-saving, thermally-enhanced 8-Pin DFN, 5-Pin TO-220, and PDIP/SOIC packages, the TC4421AVAT is suitable for applications requiring high gate/line capacitance drive, such as line drivers for heavily loaded lines, pulse generators, and driving large MOSFETs and IGBTs.
