Figure 7-12 shows the basic connections for the MAX4426/27/28 drivers. Such ICs rapidly charge and discharge the gate capacitance of the largest MOSFETs to within millivolts of the supply. The typical on resistance is 4 Ω, the delay times are 10 ns for tD1 and 25 ns for tD2, the peak output current is 1.5 A, rise and fall times are typically 20 ns with 1000-pF loads, the operating range is 4.5 V to 18 V, and the power consumption is 1.8 mA with a logic-1 output and 200 μA with a logic-0 input. The ICs are TTL/CMOS compatible and will withstand greater than 500-mA reverse current. Figure 7-13 is a test circuit. Maxrvt HIGH-RELIABILITY DATA BOOK, 1993, P. 4-5, 4-6.
