Product details

Dual 4A low-side driver for switched-mode power stages

The Texas Instruments UCC27423DR is a dual-channel, low-side gate driver designed for driving N-channel and P-channel MOSFETs in power-conversion and motor-drive circuits. Each of the two independent channels delivers a symmetric peak output current of 4A source and 4A sink, making this part suitable for switching large gate-charge devices at moderate frequencies. The inverting input logic simplifies interface to PWM controllers that require an inverted drive signal. Supply range spans 4V to 15V, covering common bias rails for 5V and 12V gate-drive stages. The 20ns rise and 15ns fall times keep cross-conduction losses low in half-bridge applications where the driver controls the low-side FET.

Independent channels and logic thresholds

Logic thresholds are 1V for VIL and 2V for VIH.

Frequently asked questions

Is UCC27423DR inverting or non-inverting?

The UCC27423DR has inverting input logic: a logic high on the input turns the output low, and a logic low turns the output high.

What parts are equivalent to UCC27423DR?

The LM5106MM/NOPB is a functionally different part — it is a half-bridge driver with non-inverting synchronous channels and lower peak output current of 1.2A. The UCC27423DR is a low-side, dual-independent, inverting driver with 4A symmetric output. These are not drop-in equivalents; compare your circuit's driven-configuration and logic-polarity requirements before substituting.
