Hey guys. I am designing a small SSTC board (halfbridge). I want to use as less space and components as it's possible. I have MCP14E8 chips at hand.

2.0A Dual High-Speed Power MOSFET Driver With Enable
High Peak Output Current: 2.0A (typical) • Independent Enable Function for Each Driver Output • Wide Input Supply Voltage Operating Range: - 4.5V to 18V • Low Shoot-Through/Cross-Conduction Current in Output Stage • High Capacitive Load Drive Capability: - tR: 12 ns with 1000 pF load (typical) - tF: 15 ns with 1000 pF load (typical) • Short Delay Times: 45 ns (typical) • Low Supply Current: - With Logic ‘1’ Input/Enable – 1 mA (typical) - With Logic ‘0’ Input/Enable – 300 µA (typical) • Latch-up Protected: Passed JEDEC JESD78A • Logic Input will Withstand Negative Swing, up to 5V • Space-Saving Packages: - 8-Lead SOIC, PDIP, 6x5 DFN
I know that people are usually using two MOSFET driver chips for GDT, but from what I seen several people succedeed using a single one, for instance:
Will MCP14E8 suffice here? How to calculate it? I am aiming at around 200kHz. Any suggestions?
PS: I have used TC4422/TC4421 pair in the past but they are big and they don't have "enable" pin. They worked well but I need something smaller for this project.
