9 / 12 page MAX17600–MAX17605 4A Sink /Source Current, 12ns, Dual MOSFET Drivers 9 Detailed Description The MAX17600–MAX17605 are high-speed MOSFET drivers capable of sinking/sourcing 4A peak currents. The devices have various inverting and noninverting part options that provide greater flexibility in controlling the MOSFET. The devices have internal logic circuitry that prevents shoot-through during output-state changes. The logic inputs are protected against voltage spikes up to +16V, regardless of VDD voltage. Propagation delay time is minimized and matched between the dual channels. The devices have very fast switching time, combined with short propagation delays (12ns typ), making them ideal for high-frequency circuits. The devices operate from a +4V to +14V single power supply and typically consume 1mA of supply current. The MAX17600/MAX17601/MAX17602 have standard TTL input logic levels, while the MAX17603/MAX17604/ MAX17605 have CMOS-like high-noise margin (HNM) input logic levels. The MAX17600/MAX17603 are dual inverting input drivers, the MAX17601/MAX17604 are dual noninverting input drivers, and the MAX17602/ MAX17605 have one noninverting and one inverting input. These devices are provided with enable pins (ENA and ENB) for better control of driver operation. Logic Inputs The MAX17600/MAX17601/MAX17602 have standard TTL input logic levels, while the MAX17603/MAX17604 / MAX17605 have CMOS-like HNM input logic levels (see the Electrical Characteristics table). Table 1 gives the truth table for various part options. Figure 3. Timing Diagram for the MAX17600/MAX17603 L = Logic-low, H = Logic-high. Figure 4. Test Circuit for the Timing Diagrams Table 1.
