3 Description

The UCC27212 device has a peak output current

of 3.7A source and 4.5A sink, which allows for the

ability to drive large power MOSFETs. The device

features an on-chip 120V rated bootstrap diode

eliminating the need for external discrete diodes.

The input structure can directly handle –10V, which

increases robustness and is also independent of

supply voltage. The UCC27212 offers 5V turn-off

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 –(24 – VDD)V maximum, which

allows the high-side channel to be protected from

inherent negative voltages.
