MAX4811CTN+

Power Management - Specialized Overview

The MAX4811CTN+ is a dual, unipolar/bipolar, high-voltage digital pulser designed for medical ultrasound imaging and sonar applications. It operates within a supply voltage range of 2.7V to 6V and draws a supply current of 36mA. The device functions reliably across an operating temperature range of 0°C to 70°C. It features low-side and high-side drain outputs with a maximum propagation delay of 15 ns. The component is housed in a 56-WFQFN exposed pad package, measuring 7x7 mm, suitable for surface mount installation.

Power Management - Specialized Procurement Notes

Verify the obsolete status and end-of-life notices prior to procurement. Confirm that the 56-TQFN package dimensions match the target PCB footprint. Ensure the supplier provides valid RoHS compliance documentation. Check for alternative sources if new production units are unavailable due to discontinuation.

Power Management - Specialized Selection Notes

Select this component for designs requiring dual-channel high-voltage pulsing in constrained spaces. Consider the 2.7V to 6V supply range compatibility with existing logic levels. Evaluate the 36mA supply current against system power budgets. Verify thermal performance within the 0°C to 70°C operational window for the intended environment.

Power Management - Specialized Part Context

The MAX4811CTN+ belongs to the MAX4811 series of specialized power management ICs. It serves as a dedicated transmit pulser for piezoelectric transducers. The device integrates necessary drive circuitry to simplify system design compared to discrete solutions.
