5 Description (continued)

The switching node of the UCC27211A (HS pin) can handle –18-V maximum, which allows the high-side channel to be protected from inherent negative voltages caused by parasitic inductance and stray capacitance. The UCC27210A (Pseudo-CMOS inputs) and UCC27211A (TTL inputs) have increased hysteresis that allows for interface to analog or digital PWM controllers with enhanced noise immunity.

The low-side and high-side gate drivers are independently controlled and matched to 2 ns between the turnon and turnoff of each other.

An on-chip 120-V rated bootstrap diode eliminates the external discrete diodes. Undervoltage lockout is provided for both the high-side and the low-side drivers which provides symmetric turnon and turnoff behavior and forces the outputs low if the drive voltage is below the specified threshold.

The UCC27211A device is offered in 8-pin SOIC (D) and 8-pin VSON (DRM) packages.
