Texas Instruments UC2715 Complementary Switch FET Drivers with Auxiliary Output UC2715DP

The UC2715 is a high-speed complementary switch FET driver designed to provide drive waveforms for power FETs in synchronous rectification and active clamp circuits. It features a single input that is compatible with PWM and TTL signals, allowing for efficient control of high-current power FETs with a source current capability of 1 A and a sink capability of 2 A. The auxiliary output driver can source 0.5 A and sink 1 A, making it suitable for additional control tasks. This driver supports programmable time delays between the power and auxiliary outputs, ranging from 50 ns to 500 ns, which facilitates soft switching transitions. The device operates with a supply voltage range of 7 V to 20 V and can handle switching frequencies up to 1 MHz. It also includes true zero-voltage sensing capability, enabling immediate activation of the corresponding switch when zero voltage is applied. The UC2715 is packaged in a 16-SOIC format and is rated for operation within a temperature range of -40¬8C to 85¬8C. Its typical propagation delays are around 50 ns, making it suitable for applications requiring fast response times. Overall, the UC2715 is a robust solution for engineers looking to implement efficient FET driving in their designs.
