MIC44F18/19/20 6A, 12.6V High Speed MOSFET Drivers with Enable Input Features General Description 4.5V to 12.6V Input Operating Range The MIC44F18, MIC44F19, and MIC44F20 are high-speed single MOSFET drivers capable of sinking 6A Peak Output Current and sourcing 6A for driving capacitive loads. With delay High Accuracy 5% Enable Input Threshold times of less than 15 ns and rise times into a 1000 pF High Speed Switching Capability load of 10 ns, these MOSFET drivers are ideal for - 10 ns Rise Time in 1000 pF Load driving large gate charge MOSFETs in power supply - <15 ns Propagation Delay Time applications. The MIC44F18 is a non-inverting driver, the MIC44F19 is an inverting driver suited for driving Flexible UVLO Function P-Channel MOSFETs, and the MIC44F20 is an - 4.2V Internally Set UVLO inverting driver for N-Channel MOSFETs. - Programmable with External Resistors Fabricated using proprietary BiCMOS/DMOS process Latch-Up Protection to >500 mA Reverse Current for low power consumption and high efficiency, the on the Output Pin MIC44F18/19/20 translates TTL or CMOS input logic Enable Function levels to output voltage levels that swing within 25 mV Thermally Enhanced ePAD MSOP-8 Package of the positive supply or ground. Comparable bipolar Option devices are capable of swinging only to within 1V of the Miniature 2 mm x 2 mm DFN-8 Package Option supply. Pb-Free Packaging The input supply voltage range of the MIC44F18/19/20 is 4.5V to 12.6V, making the devices suitable for driving Applications MOSFETs in a wide range of power applications. Other Synchronous Switch-Mode Power Supplies features include an enable function, latch-up Secondary Side Synchronous Rectification protection, and a programmable UVLO function. The MIC44F18/19/20 has a junction temperature range of 40C to +125C with exposed pad ePAD MSOP-8 and 2 mm x 2 mm DFN-8 package options.
