The UCC27212A-Q1 device driver is
based on the popular UCC27211 MOSFET drivers. In addition, UCC27212A-Q1 offers
extended operating range all the way down to 5V which helps lower power losses.
The peak output pullup and pulldown
current is 3.7A source and 4.5A sink. This allows for the ability to drive large
power MOSFETs with minimized switching losses during the e Miller Plateau of the
MOSFET.
The input structure can directly
handle –10V, which increases robustness and also allows direct interface to
gate-drive transformers without using rectification diodes. The inputs are also
independent of supply voltage and have a 20V maximum rating.
The switching node of the UCC27212A-Q1
(HS pin) can handle –(24V – VDD) maximum, which allows the high-side channel to be
protected from inherent negative voltages caused by parasitic inductance and stray
capacitance. The UCC27212A-Q1 has 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 ns between the
turn on and turn off of each other. An on-chip 120V 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 drive voltage is below the specified threshold.
