5 Description (continued)
UCC27517A features a dual input design which offers flexibility of implementing both inverting (IN- pin) and non-
inverting (IN+ pin) configurations with the same device. Either the IN+ or IN- pin can be used to control the state
of the driver output. The unused input pin can be used for enable and disable function. For protection purpose,
internal pullup and pulldown resistors on the input pins ensure that outputs are held low when input pins are in
floating condition. Hence the unused input pin is not left floating and must be properly biased to ensure that
driver output is in enabled for normal operation.
The input pin threshold of the UCC27517A device is based on TTL and CMOS compatible low-voltage logic
which is fixed and independent of the VDD supply voltage. Wide hysteresis between the high and low thresholds
offers excellent noise immunity.
6 Device Comparison Table
The UCC2751x family of gate-driver products (Table 1) represent Texas Instruments’ latest generation of single-
channel, low-side high-speed gate driver devices featuring high-source and sink current capability, industry best-
in-class switching characteristics, and a host of other features (Table 3) all of which combine to ensure efficient,
robust, and reliable operation in high-frequency switching power circuits.
