The UCC27212 device has a peak output current of 4-A source and 4-A sink, which allows for the ability to drive large power MOSFETs. The device features an on-chip 120-V rated bootstrap diode eliminating the need for external discrete diodes. The input structure can directly handle –10 V, which increases robustness and is also independent of supply voltage. The UCC27212 offers 5 V UVLO which helps lower power losses and increased input hysteresis that allows for interface to analog or digital PWM controllers with enhanced noise immunity. The switching node of the UCC27212 (HS pin) can handle –18-V maximum, which allows the high-side channel to be protected from inherent negative voltages.
