LM3708XQBP-308/NOPB

Supervisors Overview

The LM3708XQBP-308/NOPB is a voltage supervisory circuit manufactured by Texas Instruments, designed for monitoring power supply integrity in electronic systems. It features a fixed threshold voltage of 3.08 V and supports two monitored inputs. The device provides active low, open-drain outputs and includes a manual reset function alongside a watchdog timer. It operates within a supply voltage range up to 5.5 V and maintains an accuracy of 0.5%. The component is housed in a 9-VFBGA package and is rated for operation between -40°C and +85°C.

Supervisors Feature Summary

• Integrates dual input monitoring with active low open-drain output signaling
• Includes built-in watchdog timer functionality for system reliability
• Supports manual reset capability for user-initiated control

Supervisors Applications

• Microprocessor supervisory circuits
• Power supply monitoring in embedded systems
• Automotive electronics requiring voltage supervision

Supervisors Procurement Notes

Verify the specific suffix '308' corresponds to the required 3.08 V threshold for your design. Confirm the 9-VFBGA package compatibility with your PCB footprint. Ensure the automotive-grade qualification aligns with your application requirements. Cross-reference the datasheet for exact pinout and electrical characteristics before finalizing procurement.

Supervisors Selection Notes

Select this component when dual-channel voltage monitoring is required with a precise 3.08 V threshold. Consider the 9-VFBGA package size constraints and thermal performance. Evaluate the need for integrated watchdog and manual reset features versus external components. Verify that the operating temperature range meets the environmental conditions of the target application.

Supervisors Part Context

This part belongs to the LM370x series of voltage supervisors from Texas Instruments. These devices are engineered to provide reliable reset signals for microprocessors and other digital logic. The series typically offers various threshold voltages and package options to suit different design needs while maintaining high accuracy and low quiescent current.

Supervisors Replacement Considerations

Check for direct substitutes within the LM370x family with compatible thresholds and packages. Verify pin-to-pin compatibility if replacing on existing boards. Ensure any alternative maintains the same watchdog and manual reset functionalities.
