The UCC2752x family of devices are dual-channel high-speed low-side gate-driver devices capable of effectively driving MOSFET and IGBT power switches. Using a design that inherently minimizes shoot-through current, UCC2752x is capable of delivering high-peak current pulses of up to 5-A source and 5-A sink into capacitive loads along with rail-to-rail drive capability and extremely small propagation delay typically 13 ns. In addition, the drivers feature matched internal propagation delays between the two channels which are very well suited for applications requiring dual-gate drives with critical timing, such as synchronous rectifiers. This also enables connecting two channels in parallel to effectively increase current-drive capability or driving two switches in parallel with a single input signal. The input pin thresholds are 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.

The UCC2752x family provide the combination of three standard logic options — dual-inverting, dual-non inverting, one inverting and one non-inverting driver. UCC27526 features a dual input design which offers flexibility of both inverting (IN- pin) and non-inverting (IN+ pin) configuration for each channel. Either IN+ or IN- pin controls the state of the driver output. The unused input pin is used for enable and disable functions. For safety purpose, internal pullup and pulldown resistors on the input pins of all the devices in UCC2752x family ensure that outputs are held LOW when input pins are in floating condition. UCC27323, UCC27324 and UCC27325 feature Enable pins (ENA and ENB) to have better control of the operation of the driver applications. The pins are internally pulled up to VDD for active-high logic and are left open for standard operation.

UCC2752x family of devices are available in SOIC-8 (D), MSOP-8 with exposed pad (DGN) and 3-mm × 3-mm WSON-8 with exposed pad (DSD) packages. UCC27524 is also offered in PDIP-8 (P) package. UCC27526 is only offered in 3-mm × 3-mm WSON (DSD) package.
