MAQ4123
The MAQ4123/MAQ4124/MAQ4125 are a family of dual 3A buffer/MOSFET drivers intended for driving power MOSFETs, IGBTs, and other heavy loads (capacitive, resistive or inductive) which require low-impedance, high peak currents and fast switching times. They are available in inverting, non-inverting, and complementary configurations.
The MAQ4123/MAQ4124/MAQ4125 operate from a 4.5V to 20V supply, feature an output resistance of 2.3Ω, sink or source 3A of peak current, and switch an 1800pF capacitive load in 10ns with typical propagation delay times of 50ns.
The MAQ4123/MAQ4124/MAQ4125 feature TTL or CMOS compatible inputs with 400mV of hysteresis to provide noise immunity. The inputs can withstand negative voltage swings of 5V and are latch-up protected to withstand 200mA of reverse current.
The MAQ4123/MAQ4124/MAQ4125 are rated for the -40°C to +125°C operating temperature range, have been AEC-Q100 qualified for automotive applications, and are available in the ePad SOIC-8 package for improved power dissipation and thermal performance required by automotive applications.
