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 V
DD
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.
