UCC44273
- 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
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.
