LM3703XCBP-308

Supervisors Overview

The LM3703XCBP-308 is a single-channel power supply management circuit manufactured by Texas Instruments. It is housed in a BGA9 package, specifically an FBGA micro bump surface-mount device. The component operates with a supply voltage range from 1.2 V to 5.5 V, with a nominal voltage of 1.8 V. It features a reset threshold voltage of 3.08 V. The device supports an operating temperature range from -40°C to 85°C and contains one channel and one functional unit within the nine-terminal grid array fine pitch package.

Supervisors Feature Summary

• Integrates power supply management functions within a compact surface-mount footprint
• Provides precise voltage monitoring with a fixed reset threshold
• Operates efficiently across a wide industrial temperature range

Supervisors Applications

• Portable electronic devices requiring low-voltage power supervision
• Battery-powered systems needing reliable reset generation
• Embedded circuits utilizing 1.8 V logic standards

Supervisors Procurement Notes

Verify the specific suffix XCBP-308 against official Texas Instruments documentation to confirm the exact reset threshold and package variant. Ensure compatibility with the target PCB layout for the BGA9 footprint. Cross-reference the thermal specifications with the application environment to guarantee operation within the -40°C to 85°C range. Confirm that the 1.2 V to 5.5 V supply range aligns with the system design requirements.

Supervisors Selection Notes

Select this component when a dedicated power supply manager is required for single-channel applications. The fixed 3.08 V threshold suits systems where this specific voltage level triggers a reset event. The BGA9 package is suitable for space-constrained designs. Consider the operating temperature range if the environment exceeds standard commercial limits. Verify that the supply voltage remains within the specified 1.2 V to 5.5 V window during all operational states.

Supervisors Part Context

This part belongs to the LM3703 series of power supply management circuits from Texas Instruments. These components are designed to monitor supply voltages and generate reset signals for digital systems. The series typically offers various threshold options and package types to accommodate different design constraints. The LM3703XCBP-308 specifically utilizes a BGA9 package and a 3.08 V threshold.

Supervisors Replacement Considerations

Consult official Texas Instruments substitution guides for verified alternatives. Ensure any replacement matches the BGA9 package, 3.08 V threshold, and -40°C to 85°C temperature range. Generic equivalents may not provide identical reset timing or voltage accuracy.
