Microchip Technology, Inc. 6A Non-Inverting Peak Low Side MOSFET Driver MIC4120

Description
MIC4120 and MIC4129 MOSFET drivers are tough, efficient, and easy to use. The MIC4129 is an inverting driver, while the MIC4120 is a non-inverting driver. The MIC4120 and MIC4129 are improved versions of the MIC4420 and MIC4429. They are capable of 6A (peak) output and can drive the largest MOSFETs with an improved safe operating margin. The MIC4120/4129 accept any logic input from 2.4V to VS without external speed-up capacitors or resistor networks. Proprietary circuits allow the input to swing negative by as much as 5V without damaging the part. Additional circuits protect against damage from electrostatic discharge. MIC4120/4129 drivers can replace three or more discrete components, reducing PCB area requirements, simplifying product design, and reducing assembly cost. Modern BiCMOS/DMOS construction guarantees freedom from latch-up. The rail-to-rail swing capability insures adequate gate voltage to the MOSFET during power up/down sequencing. Additional Features CMOS construction Latch-up protected: will withstand >200mA reverse output current Logic input withstands negative swing of up to 5V Matched rise and fall times of 25ns High peak output current at 6A Wide operating range from 4.5V to 20V High capacitive load drive of 10,000pF Low delay time of 55ns typical Logic high input for any voltage from 2.4V to VS Low equivalent input capacitance (typ) at 6pF Low supply current is 450µA with logic 1 input Low output impedance is 2.5Ω Output voltage swing within 25mV of ground or VS Exposed backside pad packaging reduces heat ePad SOIC-8L (θJA = 58°C/W)

The MIC4120 is a non-inverting 6A peak low-side MOSFET driver designed for switch mode power supplies, motor controls, pulse transformer drivers, and class-D amplifiers. It is available in an exposed pad SOIC-8L package with a thermal resistance of 58°C/W or a 3mm x 3mm MLF-8L package with 60°C/W thermal resistance. The device operates from 4.5V to 20V supply voltage, accepts logic inputs from 2.4V to V_S, and withstands negative input swings up to 5V. It features matched rise and fall times of 25ns, a typical delay time of 55ns, peak output current of 6A, and latch-up protection withstanding over 200mA reverse current. Output voltage swing is within 25mV of supply or ground. CMOS construction ensures freedom from latch-up, and the part meets ESD protection standards for human body model circuitry.
