詳細說明
The UCC27524A is a versatile dual-channel gate-driver device designed to effectively drive MOSFET and IGBT power switches with precision and efficiency. With its ability to handle -5 V directly at the input pins, this variant of the UCC2752x family offers increased robustness and reliability. The UCC27524A features a dual non-inverting driver configuration that minimizes shoot-through current, allowing it to deliver high-peak current pulses of up to 5A source and 5A sink into capacitive loads. With rail-to-rail drive capability and a small propagation delay of typically 13 ns, this device is ideal for applications requiring critical timing, such as synchronous rectifiers
