UCC27524ADGNR Product Details

The UCC27524ADGNR device is a dual-channel, high-speed, low-side, gate-driver device capable of effectively driving MOSFET and IGBT power switches. The UCC27524ADGNR is a variant of the UCC2752x family. The UCC27524ADGNR adds the ability to handle –5 V directly at the input pins for increased robustness. The UCC27524ADGNR is a dual non-inverting driver. Using a design that inherently minimizes shoot-through current, the UCC27524ADGNR 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.

For safety purpose, internal pull-up and pull-down resistors on the input pins of the UCC27524ADGNR ensure that outputs are held LOW when input pins are in floating condition. UCC27524ADGNR features 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.

UCC27524ADGNR family of devices are available in SOIC-8 (D), VSSOP-8 with exposed pad (DGN) packages.
