MAX253CUA-T

Power Management - Specialized Overview

The MAX253CUA-T is a monolithic oscillator and power driver designed to provide isolated power for isolated RS-485 or RS-232 data interfaces. It drives a center-tapped transformer primary from a 5V or 3.3V DC supply. The device operates with a supply voltage range of 2.5V to 6V and delivers an output current of 1A. It features a non-inverting configuration and consumes 450µA of operating supply current. Power dissipation is rated at 727mW. The component functions within a temperature range of 0°C to +70°C and is housed in an 8-pin UMAX package.

Power Management - Specialized Feature Summary

Integrates oscillator and power driver for primary-side transformer excitation
Provides galvanic isolation support for serial communication interfaces
Operates directly from standard 3.3V and 5V logic supplies

Power Management - Specialized Applications

Isolated RS-485 interface power generation
Isolated RS-232 interface power generation
Primary-side drive for isolated DC-DC converters

Power Management - Specialized Procurement Notes

Verify the specific suffix designation when ordering, as 'T' indicates tape-and-reel packaging while '+' denotes lead-free/RoHS compliance. Confirm availability status through authorized distributors, as stock levels may vary by region. Ensure the selected variant matches the required thermal and electrical specifications for the target application environment.

Power Management - Specialized Selection Notes

Select this component when designing isolated serial communication links requiring integrated oscillation and drive capabilities. It is suitable for applications needing compact solutions for driving small transformers. Consider the UMAX package size and operating temperature range relative to the system constraints. Verify compatibility with the intended transformer primary winding configuration.

Power Management - Specialized Part Context

The MAX253 belongs to a family of specialized gate drivers and transformer drivers developed by Maxim Integrated, now part of Analog Devices.
