Microchip | MIC4421AZN

The MIC4421AZN is a inverting low side MOSFET driver with a peak output current of 9 A, available in surface mount PDIP-8 package.

This device accepts any logic input from 2.4 V to VS without external speed-up capacitors or resistor networks and also it can replace three or more discrete components, reducing PCB area requirements, simplifying product design, and reducing assembly cost.

Features:

• High peak-output current: 9 A Peak (typ.)
• Wide operating range: 4.5 V to 18 V (typ.)
• Minimum pulse width: 50 ns
• Latch-up proof: fully isolated process is inherently immune to any latch-up
• Input will withstand negative swing of up to 5 V
• High capacitive load drive: 47,000 pF
• Low delay time: 15 ns (typ.)
• Logic high input for any voltage from 2.4 V to VS
• Low equivalent input capacitance: 7 pF (typ.)
• Low supply current: 500 μA (typ.)
• Output voltage swing to within 25 mV of GND or VS

Applications:

• Switch mode power supplies
• Motor controls
• Pulse transformer driver
• Class-D switching amplifiers
• Line drivers
• Driving MOSFET or IGBT parallel chip modules
• Local power ON/OFF switch
• Pulse generators
