Texas Instruments UCC44273 Single-Channel Gate Driver

Texas Instruments UCC44273 Single-Channel Gate Driver is a high-speed and low-side gate driver that effectively drives MOSFET and IGBT power switches. This driver provides a 4A source and 4A sink (symmetrical drive) peak-drive current capability at 12V_DD. The UCC44273 gate driver can source and sink high peak-current pulses into capacitive loads that offer rail-to-rail drive capability and a small propagation delay of 13ns. This single-channel gate driver operates from a 4.5V to 18V voltage range and a -40°C to 140°C wide temperature range. The UCC44273 driver is ideal for Power Factor Correction (PFC) stages, residential air conditioning (HVAC), Switch Mode Power Supplies (SMPS), and motor drives.

Features

4A peak source and sink symmetrical drive
Ability to handle negative voltages (-5V) at inputs
13ns typical fast propagation delays
Fast rise and fall times (9ns and 7ns typical)
4.5V to 18V single supply range
-40°C to 140°C operating temperature range
Hysteretic-logic thresholds for high-noise immunity
Outputs held low during V_DD UVLO (ensures glitch-free operation at power up and power down)

TTL and CMOS compatible input-logic threshold (independent of supply voltage)
Output held low when input pin is floating
Input pin absolute maximum voltage levels not restricted by V_DD pin bias supply voltage
Industry standard pinout
5pin DBV (SOT-23) package option
