MAX4811CTN+TG5E

Power Management - Specialized Overview

The MAX4811CTN+TG5E is a dual, high-voltage digital pulser manufactured by Analog Devices Inc./Maxim Integrated. It operates on a supply voltage range of 2.7V to 6V with a supply current of 36mA. The device features low-side and high-side drain outputs with a maximum propagation delay of 15 ns. Packaged in a 56-WFQFN (7x7) exposed pad surface-mount package, it supports commercial operating temperatures from 0°C to +70°C. This component is designed for medical ultrasound imaging and sonar applications.

Power Management - Specialized Feature Summary

• Integrates an active clamp architecture to reduce second harmonic output and improve image quality
• Provides independent configuration for unipolar or bipolar pulse signals from low-voltage logic inputs
• Includes three logic inputs and two independent enable inputs per channel for reliable MOSFET turn-off

Power Management - Specialized Applications

• Medical Ultrasound Imaging
• Sonar Systems
• Portable Ultrasound Imaging
• Industrial Flaw Detection

Power Management - Specialized Procurement Notes

Verify part status carefully as listings indicate discontinuation at major distributors like DigiKey and limited availability at Mouser. Confirm RoHS compliance and check for valid datasheets before procurement. Due to potential supply restrictions, validate lead times and stock levels directly with authorized suppliers to ensure component authenticity and availability for production needs.

Power Management - Specialized Selection Notes

Select the MAX4811CTN+TG5E when both pulse generation and overvoltage protection are required, distinguishing it from the MAX4810 (protection only) and MAX4812 (no protection). Ensure system design accommodates the specific power rail requirements of up to +220V positive and -200V negative supplies. Verify that the 56-TQFN package fits within the board space constraints of portable or dense industrial systems.

Power Management - Specialized Part Context

This component belongs to the MAX4810/MAX4811/MAX4812 series of dual, unipolar/bipolar, high-voltage digital pulsers. These devices are engineered for systems requiring strict control over board space and performance. The series utilizes innovative active clamp architectures to enhance signal integrity and allows full control over each driver's output stage for optimized pulse generation.

Power Management - Specialized Replacement Considerations

Public confirmed substitutes include MAX4810CTN+TG5E and MAX4812CTN+TG5E. Note that MAX4810 offers clamped output overvoltage protection without pulse generation, while MAX4812 provides pulse output without overvoltage protection. All share the same 56-TQFN package and pinout compatibility.
