LM3707XQBP-308/NOPB

Supervisors Overview

The LM3707XQBP-308/NOPB is a voltage supervisory circuit manufactured by Texas Instruments. It monitors a single input channel with a threshold voltage of 3.08 V. The device features an active low, open drain output and includes manual reset capability. It incorporates a watchdog timer for system reliability. The maximum supply voltage is 5.5 V, and the reset delay time is specified as 9 µs. It operates within a temperature range of -40 °C to +125 °C and is housed in a 9-USMD package.

Supervisors Feature Summary

• Monitors a single voltage input channel with a fixed threshold
• Provides active low open drain output signal
• Includes integrated watchdog timer functionality
• Supports manual reset input for system control

Supervisors Applications

• Microprocessor power supply monitoring
• Embedded system reset generation
• Industrial control board supervision

Supervisors Procurement Notes

Verify the exact datasheet revision and package marking against the manufacturer's official documentation before procurement. Confirm that the 9-USMD package dimensions match your PCB footprint requirements. Ensure the operating temperature range meets your specific application environment constraints. Cross-reference the part number suffixes to confirm RoHS compliance and lead-free status as per current manufacturing standards.

Supervisors Selection Notes

Select this component when a single-channel supervisor with watchdog functionality is required. The 3.08 V threshold suits applications monitoring 3.3 V logic systems. Consider the 9-USMD package size for space-constrained designs. Verify that the open drain output interface is compatible with the downstream microcontroller or FPGA reset pin requirements.

Supervisors Part Context

This part belongs to the LM370x family of supervisory circuits from Texas Instruments. These devices are designed to provide reliable reset signals for digital systems. The LM3707 variant specifically offers a single monitored channel with watchdog features, distinguishing it from multi-channel or simpler reset-only counterparts in the same product line.
