UCC27714D

The UCC27714D is a high-/low-side Gate Driver with 4A source and 4A sink current capability, targeted to drive power MOSFETs or IGBTs. The device comprises of one ground-referenced channel (LO) and one floating channel (HO) which is designed for operating with bootstrap supplies. The device features excellent robustness and noise immunity with capability to maintain operational logic at negative voltages of up to -8VDC on HS pin (at VDD=12V). The device accepts a wide range bias supply input from 10 to 20V and offers UVLO protection for both the VCC and HB bias supply pins.

• High-/low-side configuration with independent inputs
• Fully operational up to 600V (HS pin)
• Floating channel designed for bootstrap operation
• Best-in-class propagation delay (125ns maximum)
• Best-in-class delay matching (20ns maximum)
• TTL and CMOS compatible input logic
• Bias UVLO protection for both channels
• Rail-to-rail drive
• Robust operation under negative voltage transients
• High dv/dt immunity (HS pin)
• Separated grounds for logic (VSS) and driver (COM) with capability to sustain voltage difference
• Optional enable function (pin 4)
• Outputs held in low when inputs floating
• Inputs and enable pin-voltage levels not restricted by VDD pin bias supply voltage
• High and low voltage pins separated for maximum creepage and clearance
• Negative voltage handling capability on input and enable pins
• Green product and no Sb/Br
