Detailed Description for MAX253ESA+
Product Overview
The MAX253ESA+ from Analog Devices Inc./Maxim Integrated is a specialized power management integrated circuit intended for transformer driver use in compact surface-mount hardware. It is packaged in an 8-SOIC package with a 0.154-inch, 3.90 mm width, making it suitable for boards that require a small outline IC footprint. The device operates from either 3.3 V or 5 V supply conditions and is specified across a -40°C to 85°C operating temperature range. Its primary function is driving a transformer, which supports circuit designs that use transformer-coupled signal paths or related communication interface hardware.
Key Features
- Transformer driver function for use in power management and signal-path circuits
- Operates from 3.3 V or 5 V supply voltage
- Supply current of 450 µA
- Specified operating temperature range of -40°C to 85°C
- Surface-mount 8-SOIC package with 0.154-inch, 3.90 mm width
Applications
- RS485-related communication interface hardware
- Power management subsystems requiring transformer drive
Design & Procurement Notes
Designers selecting the MAX253ESA+ should confirm that the board power architecture can provide either 3.3 V or 5 V, since these are the specified supply conditions. The 450 µA supply current should be included in low-power budget calculations, while the -40°C to 85°C temperature range should be checked against the expected ambient environment. The 8-SOIC surface-mount footprint supports space-constrained layouts, but pad geometry, transformer selection, and signal-path requirements still need to be validated against the final circuit design. Procurement specifications should retain the exact manufacturer part number to avoid package or ordering ambiguity.
