The is a dual-channel high-speed low-side power MOSFET Driver with negative input voltage ability. It is capable of effectively driving MOSFET and IGBT power switches. The UCC27524A is a variant of the UCC2752x family. The UCC27524A adds the ability to handle -5V directly at the input pins for increased robustness. The UCC27524A is a dual non-inverting driver. Using a design that inherently minimizes shoot-through current, the UCC27524A is capable of delivering high-peak current pulses of up to 5A source and 5A sink into capacitive loads along with rail-to-rail drive capability and extremely small propagation delay typically 13ns. In addition, the driver feature matched internal propagation delays between the two channels which are very well suited for applications requiring dual-gate drive with critical timing, such as synchronous rectifiers.
