TL7733BIDR

Supervisors Overview

The TL7733BIDR is a single-channel supervisor IC manufactured by Texas Instruments, designed for simple reset and power-on reset applications. It features an open-drain or open-collector output and supports both high-active and low-active reset signals. The device monitors a single voltage input with a threshold of 3.08V. It operates within a temperature range of -40°C to 85°C (TA) and utilizes an 8-SOIC surface-mount package with a width of 3.90mm. The standard transmission delay is specified at 270ns.

Supervisors Feature Summary

• Provides simple reset and power-on reset functionality for monitored circuits
• Offers configurable active-high or active-low reset signal outputs
• Features open-drain or open-collector output structure for flexible interfacing

Supervisors Applications

• Microprocessor system supervision
• Power supply monitoring in embedded systems
• Battery backup circuit protection

Supervisors Procurement Notes

Verify the specific suffix 'IDR' corresponds to the industrial temperature grade (-40°C to 85°C) and tape-and-reel packaging format. Confirm that the 3.08V threshold aligns with the target supply rail requirements. Ensure compatibility with the required reset polarity configuration for the host processor interface.

Supervisors Selection Notes

Select this component when a single-supply monitor with a fixed 3.08V threshold is required. The industrial temperature range suits broader environmental conditions compared to commercial variants. The open-drain output allows for wired-OR configurations or level shifting to different logic voltages.

Supervisors Part Context

This part belongs to the TL7733 family of voltage supervisors from Texas Instruments. It shares functional similarities with other members like the TL7733BCD but differs in operating temperature range and packaging type. The 'I' suffix denotes the industrial grade, while 'DR' indicates the reel-based surface-mount package.

Supervisors Replacement Considerations

The TL7733BCD serves as a direct alternative with identical electrical specifications but offers a commercial temperature range (0°C to 70°C) and tube packaging instead of tape-and-reel.
