6A peak gate driver in a through-hole DIP
The Maxim Integrated MAX4420CPA+ is a single-channel, low-side MOSFET gate driver delivering 6A peak source and sink current with 25ns typical rise and fall times. It accepts a supply voltage from 4.5V to 18V and drives both N-channel and P-channel MOSFETs from a non-inverting input. The 8-DIP (0.300", 7.62mm) through-hole package suits benchtop prototyping, low-volume production, or retrofitting into existing boards with DIP sockets. Operating temperature is 0°C to 70°C, so it is intended for indoor, commercial, or controlled-environment equipment rather than extended-temperature industrial or automotive applications.
25ns switching — what it means for the power stage
The 25ns typical rise and fall time at 6A drive strength means the MAX4420CPA+ can charge and discharge the MOSFET gate capacitance quickly, minimising switching losses in the power stage. This is relevant for DC-DC converters, motor drivers, and class-D amplifiers operating in the tens to low hundreds of kHz. The symmetrical 6A source and sink capability keeps the turn-on and turn-off edges balanced, which simplifies dead-time budgeting. The logic input thresholds of 0.8V (VIL) and 2.4V (VIH) are compatible with 3.3V and 5V logic families directly, so no level shifting is needed when driving from a microcontroller or PWM controller.
Active lifecycle — no LTB risk for new designs
The MAX4420CPA+ carries an Active product status with ROHS3 compliance. The through-hole DIP package is a mature, widely supported form factor, and the part is available through independent distribution channels.
