LT8204RFE#TRPBF

Overview

The LT8204RFE#TRPBF is a switching controller from Analog Devices, specifically designed as a 40V H-Bridge Controller with integrated current sense capabilities. It operates within a temperature range of -40°C to +150°C and supports a switching frequency of 1 MHz. The device is housed in a 38-pin TFSOP package with an exposed pad, suitable for surface mount applications. As a DC-DC switching controller, it functions as a full-bridge or half-bridge regulator capable of positive output step-up and step-down configurations.

Feature Summary

• Integrated current sensing functionality for precise control
• Supports both full-bridge and dual half-bridge topologies
• Wide operating temperature range up to 150°C
• High-speed switching capability at 1 MHz

Applications

• Industrial motor drive systems requiring H-bridge control
• Power supply designs utilizing full-bridge or half-bridge converters
• Applications demanding high-temperature operation environments

Procurement Notes

Verify the specific suffix TRPBF indicates tape and reel packaging when sourcing. Confirm that the 38-TSSOP-EP package matches your PCB footprint requirements. Ensure compatibility with SPI interface if digital control is required. Check for any lead-free compliance documentation relevant to your manufacturing process. Validate that the 40V rating aligns with your system's voltage constraints.

Selection Notes

Select this component when a dedicated H-bridge controller with built-in current sensing is needed. Consider the 1 MHz switching frequency for balancing efficiency and EMI. The wide temperature range makes it suitable for harsh industrial environments. Evaluate the 38-pin package size against available board space. Compare performance against other Analog Devices controllers if higher voltage ratings are required.
