Features
Description
• Two Independent Drivers, Each Capable of Sourcing
and Sinking 5A
The IX4340 is a dual, high current, low side gate
driver. Each of the two outputs is capable of sourcing
and sinking 5A of peak current, and has a maximum
voltage rating of 20V. The two outputs can be
paralleled for higher current applications. Fast
propagation delay times (16ns typical) and fast rise
and fall times (7ns) make the IX4340 well suited for
high frequency applications.
• CMOS and TTL Compatible Inputs
• Independent Enable for Each Driver
• 5V to 20V Supply Voltage Range
• -40°C to +125°C Extended Operating Temperature
Range
• ±4kV ESD Rating (Human Body Model)
• Thermally enhanced 8-pin SOIC and 8-pin MSOP
packages and standard 8-pin SOIC package
• Under Voltage Lockout Circuitry
The inputs are TTL and CMOS logic compatible, and
there is an independent Enable function for each
output. Under voltage lockout circuitry (UVLO)
prevents the high side source driver from conducting
until there is sufficient supply voltage. The outputs are
held low if the logic inputs are floating.
• Fast Propagation Delays (16ns typical)
• Fast Rise and Fall Times (7ns typical)
Applications
• Switch-Mode Power Supplies
• DC-DC Converters
• Motor Controllers
The IX4340 is available in standard 8-pin SOIC and
thermally enhanced 8-pin SOIC and MSOP packages.
• Power Inverters
