SLUSCG0A December 2015 – January 2016 UCC27211A-Q1
PRODUCTION DATA.
The switching node of the UCC27211A-Q1 (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 UCC27211A-Q1has 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 turn on and turn off 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 turn on and turn off behavior and forces the outputs low if the drive voltage is below the specified threshold.
The UCC27211A-Q1 device is offered in an 8-Pin SO-PowerPAD package.
