The switching node (HS pin) of the UCC2721x can handle –18 V maximum which allows the high-side channel to be protected from inherent negative voltages caused parasitic inductance and stray capacitance. The UCC27210 (Pseudo-CMOS inputs) and UCC27211 (TTL inputs) have increased hysteresis allowing 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 providing symmetric turnon and turnoff behavior and forcing the outputs low if the drive voltage is below the specified threshold.
Both devices are offered in 8-pin SOIC (D), PowerPAD SOIC-8 (DDA), 4-mm × 4-mm SON-8 (DRM) and SON-10 (DPR) packages.
