Microchip | MIC4427YMM

The MIC4427YMM is a part of MIC4427 family of highly-reliable dual low-side MOSFET driver fabricated on a BiCMOS/DMOS process for low power consumption and high efficiency.

The MIC4427YMM driver translate TTL or CMOS input logic levels to output voltage levels that swing within 25 mV of the positive supply or ground. Comparable bipolar devices are capable of swinging only to within 1V of the supply. The MIC4426/7/8 is available in three configurations: dual inverting, dual noninverting, and one inverting plus one noninverting output.

Features:

• Bipolar/CMOS/DMOS construction
• Latch-up protection to >500mA reverse current
• 1.5A-peak output current
• 4.5V to 18V operating range
• Low quiescent supply current
• 4 mA at logic 1 input
• 400 µA at logic 0 input
• Switches 1000pF in 25ns
• Matched rise and rall times
• 7 output impedance
• < 40ns typical delay
• Logic-input threshold independent of supply voltage
• Logic-input protection to –5V
• 6pF typical equivalent input capacitance
• 25mV max. output offset from supply or ground 

Applications:

• MOSFET driver
• Clock line driver
• Coax cable driver
• Piezoelectic transducer driver
