UCC27517 UCC27516 SLUSAY4C – MARCH 2012 – REVISED MAY 2013 www.ti.com VDD and Undervoltage Lockout The UCC2751x devices have internal Undervoltage Lockout (UVLO) protection feature on the VDD-pin supplycircuit blocks. Whenever the driver is in UVLO condition (for example when VDD voltage is less than VON during power up and when VDD voltage is less than VOFF during power down), this circuit holds all outputs LOW, regardless of the status of the inputs. The UVLO is typically 4.
PAGE 15
UCC27517 UCC27516 www.ti.com SLUSAY4C – MARCH 2012 – REVISED MAY 2013 Input Stage The input pins of the UCC27516 and UCC27517 devices are based on a TTL/CMOS compatible input-threshold logic that is independent of the VDD supply voltage. With typ high threshold = 2.2 V and typ low threshold = 1.2 V, the logic-level thresholds can be conveniently driven with PWM-control signals derived from 3.3-V and 5-V digital-power controllers.
PAGE 16
UCC27517 UCC27516 SLUSAY4C – MARCH 2012 – REVISED MAY 2013 www.ti.com Enable Function As mentioned earlier, an enable/disable function is easily implemented in the UCC27516 and UCC27517 using the unused input pin. When IN+ is pulled down to GND or IN- is pulled down to VDD, the output is disabled. Thus IN+ pin is used like an enable pin that is based on active-high logic, while IN- can be used like an enable pin that is based on active-low logic.

UCC27517 UCC27516 www.ti.com SLUSAY4C – MARCH 2012 – REVISED MAY 2013 Power Dissipation Power dissipation of the gate driver has two portions as shown in Equation 1. PDISS = PDC + PSW (1) The DC portion of the power dissipation is PDC = IQ x VDD where IQ is the quiescent current for the driver.

UCC27517 UCC27516 www.ti.com SLUSAY4C – MARCH 2012 – REVISED MAY 2013 Low Propagation Delays The UCC27516 and UCC27517 driver devices feature best-in-class input-to-output propagation delay of 13 ns (typ) at VDD = 12 V. This promises the lowest level of pulse-transmission distortion available from industrystandard gate-driver devices for high-frequency switching applications.

UCC27517 UCC27516 SLUSAY4C – MARCH 2012 – REVISED MAY 2013 www.ti.com PCB Layout Proper PCB layout is extremely important in a high-current fast-switching circuit to provide appropriate device operation and design robustness. The UCC27516 and UCC27517 gate driver incorporates short-propagation delays and powerful output stages capable of delivering large current peaks with very fast rise and fall times at the gate of the power switch to facilitate voltage transitions very quickly.
