U4793B-MY

Overview

The U4793B-MY is a current monitor integrated circuit manufactured by Microchip Technology, designed for precise current sensing applications. It operates within an input voltage range of 9V to 15V and provides a maximum output current of 20mA. The device is housed in an 8-DIP package with a width of 0.300 inches (7.62mm), suitable for through-hole mounting. It supports a wide operating temperature range from -40°C to +125°C, ensuring reliability in demanding environments. This component functions as a dedicated current monitor, offering stable performance across its specified electrical parameters.

Feature Summary

• Provides dedicated current monitoring functionality for system protection and measurement
• Supports through-hole installation via standard 8-pin DIP packaging
• Operates reliably across extended industrial temperature ranges

Applications

• Industrial control systems requiring current supervision
• Power supply monitoring circuits
• Electronic equipment protection schemes

Procurement Notes

Verify the specific suffix 'MY' corresponds to the 8-DIP through-hole package variant when ordering. Confirm that the component status is discontinued or obsolescence managed, as availability may be limited. Ensure compatibility with existing PCB footprints designed for 8-DIP packages. Check for any alternative sourcing options if new production units are required for long-term maintenance.

Selection Notes

Select this component when a through-hole current monitor is required for voltages between 9V and 15V. The 8-DIP package facilitates easy prototyping and replacement on legacy boards. Consider the 20mA output capability for interfacing with downstream logic or analog-to-digital converters. Verify thermal requirements against the -40°C to +125°C operational range for the intended environment.

Part Context

The U4793B series represents Microchip's line of current monitor ICs. The U4793B-MY specifically denotes the through-hole DIP version, distinct from surface-mount SOIC variants like the U4793B-MFPG3. This family is utilized for monitoring current levels in various electronic systems, providing a simple interface for current detection without complex external components.

Replacement Considerations

Direct substitutes include other U4793B variants such as U4793B-MFPG3 for surface-mount applications, though package differences must be addressed. Cross-reference with generic current monitors if pin compatibility allows. Verify functional equivalence regarding input voltage range and output current specifications before substitution.
