MAX4428CPA+

Overview

The MAX4428CPA+ is a dual low-side MOSFET gate driver manufactured by Analog Devices Inc./Maxim Integrated. It features independent channels with both inverting and non-inverting inputs, supporting N-channel and P-channel MOSFETs. The device operates on a supply voltage range of 4.5V to 18V and delivers a peak output current of 1.5A for both sourcing and sinking. Typical rise and fall times are 20ns. It is housed in an 8-CERDIP package with MIL-STD-883 qualification.
