Key Features
- Dual 3 A peak source and sink gate drive current per channel enables fast MOSFET switching with minimal transition losses
- Schmitt trigger input with wide 4.5 V to 18 V supply range accepts noisy logic signals without false triggering
- 8-pin ceramic CERDIP-8 package rated for -55°C to +125°C operation suits mil-spec and high-reliability industrial designs
Applications
The TC4424MJA is used in high-reliability power converter designs driving parallel MOSFET banks in DC-DC converters, UPS inverters, and motor controllers requiring fast gate transitions. Its 3 A peak gate drive current charges large gate capacitances above 10 nF in under 50 ns, reducing switching losses in hard-switched topologies. The ceramic CERDIP-8 package makes it suitable for military, aerospace, and industrial equipment operating across -55°C to +125°C temperature ranges.

Frequently Asked Questions
What peak gate drive current can TC4424MJA deliver per channel and how does this benefit MOSFET switching speed?
Each channel of the TC4424MJA can source and sink up to 3 A peak gate drive current, enabling it to charge a 10 nF gate capacitance in approximately 30 ns. This fast turn-on and turn-off reduces MOSFET switching losses in PWM converters operating at frequencies above 100 kHz.
What supply voltage range does TC4424MJA support and which logic families are compatible with its Schmitt trigger input?
The TC4424MJA operates from 4.5 V to 18 V supply voltage, supporting both 5 V TTL and 3.3 V CMOS logic inputs through its Schmitt trigger input stage. The Schmitt trigger hysteresis rejects noise spikes above 0.5 V in electrically noisy switching converter environments without false triggering.
For what operating temperature range is TC4424MJA rated and why is this important for military applications?
The TC4424MJA in ceramic CERDIP-8 package is rated for -55°C to +125°C operation, meeting MIL-STD requirements for military and aerospace gate driver applications. This wide temperature range exceeds the -40°C to +85°C of commercial plastic-package alternatives, making it the preferred choice for avionic power converters and defense electronics.
How does TC4424MJA compare to TC4420 when driving multiple parallel MOSFETs in a high-current inverter?
TC4424MJA provides 2 independent 3 A gate driver channels in a single 8-pin package, while TC4420 is a single-channel 6 A driver. For driving two separate MOSFET switches at 3 A each in a half-bridge or dual-output PWM topology, TC4424MJA reduces the component count by 50% and saves approximately 30% PCB area compared to using two separate TC4420 devices.
