Dual MOSFET Driver

The MAX17600–MAX17605 devices from Maxim are high-speed MOSFET drivers capable of sinking /sourcing 4 A peak currents. The devices have various inverting and non-inverting 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 resist voltage spikes up to +14 V, regardless of VDD voltage. Propagation delay time is minimized and matched between the dual channels. The devices' fast switching time, combined with short propagation delays (12 ns), make them ideal for high-frequency circuits. The devices operate from a +4 V to +14 V single power supply typically consuming 1 mA of supply current. The MAX17600/MAX17601 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, and the MAX17601/MAX17604 are dual non-inverting input drivers. The MAX17602 / MAX17605 devices have one non-inverting and one inverting input. These devices are provided with enable pins (ENA, ENB) for better control of driver operation.
