MAQ4123/MAQ4124/MAQ4125 Automotive AEC-Q100 Qualified Dual 3A Peak Low-Side MOSFET Driver Bipolar/CMOS/DMOS Process General Description Features The MAQ4123/MAQ4124/MAQ4125 are a family of dual Automotive AEC-Q100 Qualified 3A buffer/MOSFET drivers intended for driving power High 3A peak output current MOSFETs, IGBTs and other heavy loads (capacitive, Wide 4.5V to 20V supply voltage range resistive or inductive) which require low-impedance, high Low 2.3 output resistance peak currents and fast switching times. They are available in inverting, non-inverting and complementary Matched rise and fall times configurations. Fast 10ns rise/fall times with 1800pF capacitive load The MAQ4123/MAQ4124/MAQ4125 operate from a 4.5V Low propagation delay time of 50ns (typical) to 20V supply, feature an output resistance of 2.3, sink or TTL/CMOS logic inputs independent of supply voltage source 3A of peak current, and switch an 1800pF Latch-up protected to 200mA reverse current capacitive load in 10ns with typical propagation delay Logic input withstands swing to 5V times of 50ns. Low equivalent 6pF input capacitance The MAQ4123/MAQ4124/MAQ4125 feature TTL or CMOS compatible inputs with 400mV of hysteresis to provide Output voltage swings within 25mV of ground or VS noise immunity. The inputs can withstand negative voltage Low supply current swings of 5V and are latch-up protected to withstand 2.0mA with logic-1 input (maximum over 200mA of reverse current. temperature) The MAQ4123/MAQ4124/MAQ4125 are rated for the 300 A with logic-0 input (maximum over 40 C to +125C operating temperature range, have been temperature) AEC-Q100 qualified for automotive applications, and are 426/7/8-, 1426/7/8-, 4426/7/8 industry standard pin available in the ePad SOIC-8 package for improved power out dissipation and thermal performance required by Inverting, non-inverting, and differential configurations automotive applications. 40C to +125 C temperature range Data sheets and support documentation can be found on Micrels web site at: www.micrel.com.
