MAX258ATA+T

Overview

The MAX258ATA+T is a silicon oscillator and power driver designed for isolated power supplies. It operates with a supply voltage range of 3V to 5.5V and delivers up to 500mA of continuous current. The device features undervoltage lockout and thermal shutdown protection, along with a low-current shutdown mode. It is housed in an 8-pin TDFN package and functions within a temperature range of -40°C to +125°C.

Feature Summary

• Integrated silicon oscillator eliminates external timing components
• Push-pull output stage provides 500mA drive capability
• Includes undervoltage lockout and thermal shutdown protection

Applications

• Isolated DC-DC converter designs
• Flyback transformer drivers
• Industrial control systems requiring galvanic isolation

Procurement Notes

Verify the specific suffix (+T) indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status through official Analog Devices documentation. Check current availability as distribution may vary by region. Ensure the supplier provides valid traceability for automotive or industrial grade requirements if applicable.

Selection Notes

Select this component for applications requiring a compact solution for driving isolated flyback transformers. The integrated oscillator simplifies design compared to discrete gate drivers. Verify that the 500mA output current meets the transformer primary side requirements. Consider the TDFN package size constraints during PCB layout.
