The supply voltage spans 10V to 32V, covering 12V and 24V industrial rails as well as automotive battery voltages. Logic input thresholds are 1.2V (VIL) and 2.2V (VIH), compatible with 3.3V and 5V controller outputs without external level shifting.
The 140°C TJ ceiling provides margin above the typical 125°C industrial limit.
The UCC27538DBVR is a single-channel driver. Driving two parallel MOSFETs is possible if the total gate charge stays within the driver's 2.5A source / 5A sink peak capability and the switching frequency is derated accordingly — but a dual-channel driver like the UCC27539DBVR is the cleaner choice for two independent gates.
The UCC27538DBVR is a single-channel non-inverting driver; the UCC27539DBVR is a dual-channel non-inverting driver. Both share the same SOT-23-6 package, supply range, and output current ratings. Choose the UCC27538DBVR for one gate and the UCC27539DBVR for two independent gates.
