MAQ4123/MAQ4124/MAQ4125
Automotive AEC-Q100 Qualified Dual
3A Peak Low-Side MOSFET Driver
Bipolar/CMOS/DMOS Process
General Description
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.
