MIC44F18/19/20

6A, 12.6V High Speed MOSFET Drivers with Enable Input

Features

General Description

• 4.5V to 12.6V Input Operating Range

• 6A Peak Output Current

The MIC44F18, MIC44F19, and MIC44F20 are

high-speed single MOSFET drivers capable of sinking

and sourcing 6A for driving capacitive loads. With delay

times of less than 15 ns and rise times into a 1000 pF

load of 10 ns, these MOSFET drivers are ideal for

driving large gate charge MOSFETs in power supply

applications. The MIC44F18 is a non-inverting driver,

the MIC44F19 is an inverting driver suited for driving

P-Channel MOSFETs, and the MIC44F20 is an

inverting driver for N-Channel MOSFETs.

• High Accuracy ±5% Enable Input Threshold

• High Speed Switching Capability

- 10 ns Rise Time in 1000 pF Load

- <15 ns Propagation Delay Time

• Flexible UVLO Function

- 4.2V Internally Set UVLO

- Programmable with External Resistors

Fabricated using proprietary BiCMOS/DMOS process

for low power consumption and high efficiency, the

MIC44F18/19/20 translates 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.

• Latch-Up Protection to >500 mA Reverse Current

on the Output Pin

• Enable Function

• Thermally Enhanced ePAD MSOP-8 Package

Option

• Miniature 2 mm x 2 mm DFN-8 Package Option

• 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

MOSFETs in a wide range of power applications. Other

features include an enable function, latch-up

protection, and a programmable UVLO function.

Applications

• Synchronous Switch-Mode Power Supplies

• Secondary Side Synchronous Rectification

The MIC44F18/19/20 has a junction temperature range

of –40°C to +125°C with exposed pad ePAD MSOP-8

and 2 mm x 2 mm DFN-8 package options.
