The bootstrap high-side voltage is rated to 120V, covering 48V, 72V, and 100V bus rails with margin. Supply range is 8V to 17V, which aligns with standard 12V bias rails in industrial and automotive systems.
The 3A peak output current on both source and sink allows the driver to charge and discharge the gate capacitance of large MOSFETs quickly.
Yes. With 3A peak output and 8ns/7ns typical rise/fall times, the driver supports switching frequencies in the hundreds of kilohertz range. The actual maximum frequency depends on the total gate charge of the MOSFETs and the thermal budget.
Yes. The logic VIH threshold is 2.5V, so a 5V PWM signal from a microcontroller or DSP is reliably recognized as a logic high. The input is non-inverting.
A close functional peer is the LM5106MM/NOPB from Texas Instruments, also a half-bridge N-channel MOSFET driver in a surface-mount package. The LM5106 has a 1.2A peak output and 15ns/10ns rise/fall times, compared to the UCC27201D's 3A and 8ns/7ns. The UCC27201D offers stronger drive and faster edges, which matters for larger MOSFET gates or higher switching frequencies. The LM5106 has a synchronous channel type versus the UCC27201D's independent channels, so the bootstrap and dead-time implementation differ. Pin compatibility should be verified against the respective datasheets before substit
