General Description

The MIC44F18, MIC44F19 and MIC44F20 are high-

speed single MOSFET drivers capable of sinking and

sourcing 6A for driving capacitive loads.

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

load of 10ns, these MOSFET drivers are ideal for driving

large

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.

Fabricated using Micrel’s 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 25mV of

the positive supply or ground. Comparable bipolar

devices are capable of swinging only to within 1V of the

supply.

The input supply voltage range of the MIC44F18/19/20

is 4.5V to 13.2V, 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.

The MIC44F18/19/20 has a junction temperature range

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

and 2mm x 2mm MLF
