LTC4441/LTC4441-1  
N-Channel MOSFET  
Gate Driver  
U
FEATURES  
DESCRIPTIO  
The LTC®4441/LTC4441-1 is an N-channel MOSFET gate  
driver that can supply up to 6A of peak output current. The  
chip is designed to operate with a supply voltage of up to  
25V and has an adjustable linear regulator for the gate  
drive. The gate drive voltage can be programmed between  
5V and 8V.  
■
6A Peak Output Current  
■
Wide VIN Supply Range: 5V to 25V  
■
Adjustable Gate Drive Voltage: 5V to 8V  
■
Logic Input can be Driven Below Ground  
■
30ns Propagation Delay  
■
Supply Independent CMOS/TTL Input Thresholds  
■
Undervoltage Lockout  
The LTC4441/LTC4441-1 features a logic threshold driver  
input. This input can be driven below ground or above the  
driver supply. A dual function control input is provided to  
disable the driver or to force the chip into shutdown mode  
with <12µA of supply current. Undervoltage lockout and  
overtemperature protection circuits will disable the driver  
output when activated. The LTC4441 also comes with an  
open-drain output that provides adjustable leading edge  
blanking to prevent ringing when sensing the source  
current of the power MOSFETs.  
■
Low Shutdown Current: <12µA  
■
Overtemperature Protection  
■
Adjustable Blanking Time for MOSFET’s  
Current Sense Signal (LTC4441)

APPLICATIO S  
■
Power Supplies  
The LTC4441 is available in a thermally enhanced 10-lead  
MSOP package. The LTC4441-1 is the SO-8 version with-  
out the blanking function.
