SLUSFA6 – OCTOBER 2023

UCC44273 4-A, 4-A Single-Channel Low-Side Driver with 5-V UVLO

1 Features

3 Description

•

5-pin DBV (SOT-23) package option

Industry standard pinout

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.

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 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.

•

2 Applications

•

Power factor correction (PFC) stages

Residential air conditioning (HVAC)

Switch-mode power supplies

Motor drives

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.
