The MAX4426/MAX4427/MAX4428 are dual monolithic MOSFET drivers designed to translate TTL/CMOS inputs to high voltage/current outputs. The MAX4426 is a dual inverting power MOSFET driver. The MAX4427 is a dual noninverting power MOSFET driver, and the MAX4428 contains one inverting section and one noninverting section. Delay times are nearly independent of VDD (see Typical Operating Characteristics in the full data sheet). High-current output drivers rapidly charge and discharge the gate capacitance of even the largest power MOSFETs to within millivolts of the supply rails. This produces the power MOSFETs' minimum on resistance. The MAX4426/MAX4427/MAX4428's high speed minimizes power losses in switching power supplies and DC-DC converters.
Key Features
- Upgrade for TSC4426/TSC4427/TSC4428
- Lower On Resistance: 4Ω vs. 7Ω
- Shorter Delay Times:
- tD1—10ns vs. 30ns
- tD2—25ns vs. 50ns
- 1.5A Peak Output Current
- Fast Rise and Fall Times: Typically 20ns with 1000pF Load
- Wide Operating Range: 4.5V to 18V
- Low Power Consumption:
- 1.8mA with Logic 1 Input
- 200µA with Logic 0 Input
- TTL/CMOS Compatible
- Latchup Protected-Withstand > 500mA Reverse Current
- ESD Protected
Applications/Uses
- Charge-Pump Voltage Inverters
- DC-DC Converters
- Motor Controllers
- Pin-Diode Drivers
- Switching Power Supplies
