Product details

Dual 5A low-side driver — what it drives and how fast

It drives N-channel MOSFETs and IGBTs from a 4.5V to 18V supply rail — covering standard 5V, 12V, and 15V gate drive voltages without an extra regulator. The two channels are independent with inverting input logic, meaning a logic HIGH on the input turns the gate OFF. This inverting polarity is a deliberate choice for control loops where the PWM signal needs to be inverted at the driver stage.

Thermal headroom and package — where it survives

Surface-mount only — the 0.118-inch body width and exposed pad suit compact power stages on 2-layer or 4-layer boards. The pad is the primary heat path; a solid copper pour with at least four vias under the pad keeps the driver within its thermal budget during continuous 5A gate charge cycles.

Frequently asked questions

What is the difference between UCC27523DGNR and UCC27524DGNR?

The UCC27523 has inverting inputs (logic HIGH = gate OFF), while the UCC27524 has non-inverting inputs (logic HIGH = gate ON). Both are dual 5A low-side drivers in the same package with identical rise/fall times and supply range. The choice depends on your PWM polarity — if your controller outputs active-high PWM, the UCC27524 matches directly; if you need inversion at the driver stage, the UCC27523 saves an external inverter gate.

Can UCC27523DGNR drive SiC MOSFETs?

The 4.5V to 18V supply range and 5A peak drive current can handle many SiC MOSFETs that require 15V to 18V gate drive and fast switching edges. However, SiC devices often need a negative gate turn-off voltage (e.g., -5V) to prevent false turn-on during hard switching — this driver is a single-supply low-side driver and does not provide a negative rail. For SiC with negative gate drive, a dedicated isolated driver with dual supply rails is a better fit.

Does UCC27523DGNR require an external bootstrap diode for high-side drive?

No — this is a low-side driver, not a half-bridge driver. It drives ground-referenced switches only. For high-side N-channel MOSFETs you need a bootstrap circuit or an isolated supply; this part does not include a bootstrap diode or high-side level shifter.
