The TelCom TSC427CPA is a dual power MOSFET driver designed to drive the gate of a power MOSFET from a logic-level input. It takes a low-current digital signal and delivers the peak current needed to charge and discharge the gate capacitance quickly, reducing switching losses in the power stage. Typical applications include switch-mode power supplies, motor drives, and DC-DC converters where two independent MOSFETs need to be driven, such as a half-bridge or synchronous rectifier.
The TSC427CPA is RoHS non-compliant. If your assembly line or end-product requires RoHS compliance, this part will not pass incoming inspection. It is a fit for legacy designs, repair stock, or projects with a RoHS exemption. For new RoHS-mandated builds, a compliant alternative in the same functional family would be needed.
There is no evidence of a last-time-buy or discontinuation notice. The part is RoHS non-compliant, so it may not be stocked by all distributors.
