UCC44273DBVR规格书详情
1 Features
• 5-pin DBV (SOT-23) package option
• Industry standard pinout
• 4-A peak source and sink symmetrical drive
• Ability to handle negative voltages (–5 V) at inputs
• Fast propagation delays (13 ns typical)
• Fast rise and fall times (9 ns and 7 ns typical)
• 4.5-V to 18-V single supply range
• Outputs held low during VDD UVLO (ensures
glitch-free operation at power up and power down)
• TTL and CMOS compatible input-logic threshold
(independent of supply voltage)
• Hysteretic-logic thresholds for high-noise immunity
• Output held low when input pin is floating
• Input pin absolute maximum voltage levels not
restricted by VDD pin bias supply voltage
• Operating temperature range of –40°C to 140°C
2 Applications
• Power factor correction (PFC) stages
• Residential air conditioning (HVAC)
• Switch-mode power supplies
• Motor drives
3 Description
The UCC44273 single-channel, high-speed, low-side
gate driver device is capable of effectively driving
MOSFET and IGBT power switches. Using a design
that inherently minimizes shoot-through current, the
UCC44273 is capable of sourcing and sinking high
peak-current pulses into capacitive loads offering
rail-to-rail drive capability and extremely small
propagation delay typically 13 ns.
The UCC44273 device is capable of handling –5 V at
the input pins. The UCC44273 provides 4-A source
and 4-A sink (symmetrical drive) peak-drive current
capability at VDD = 12 V.
The UCC44273 is designed to operate over a wide
VDD range of 4.5 V to 18 V and wide temperature
range of –40°C to 140°C. Internal Undervoltage
Lockout (UVLO) circuitry on VDD pin holds output low
outside VDD operating range.
The input pin threshold of the UCC44273 device is
based on TTL and CMOS compatible low-voltage
logic which is fixed and independent of the VDD
supply voltage. Wide hysteresis between the high and
low thresholds offers excellent noise immunity.
