TL7700CDGKT

Supervisors Overview

The TL7700CDGKT is a voltage supervisory circuit manufactured by Texas Instruments, designed to monitor power supply integrity. It operates within a supply voltage range of 1.8 V to 40 V and features an adjustable threshold for under-voltage detection at 495 mV and over-voltage detection at 505 mV. The device provides a programmable reset delay time and utilizes an active low, open-drain output configuration. Packaged in an 8-pin VSSOP format, it supports surface-mount installation and functions reliably across a temperature range of -40°C to +85°C with a typical accuracy of 2%.

Supervisors Feature Summary

• Provides active low, open-drain output signaling for power supply monitoring
• Features adjustable threshold voltages for customizable under-voltage and over-voltage detection
• Includes programmable reset delay timing capabilities
• Operates with a wide input voltage range up to 40 V

Supervisors Applications

• Power-on reset generation in embedded systems
• Battery-powered device supervision
• Microcontroller system protection circuits
• Portable equipment power management

Supervisors Procurement Notes

Verify the specific suffix 'KT' against official Texas Instruments documentation to confirm tape-and-reel packaging specifications and exact pinout compatibility. Ensure the selected variant matches the required operating temperature range and package dimensions for your PCB layout. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and current production status before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a single-channel supervisory circuit with adjustable thresholds is required. Consider the VSSOP-8 package for space-constrained designs. Evaluate the need for programmable reset delays versus fixed delays based on system startup requirements. Confirm that the 1 mA supply current aligns with the application's power budget constraints.

Supervisors Part Context

The TL7700 belongs to Texas Instruments' family of voltage supervisory circuits. This series is categorized under PMIC (Power Management ICs) and specifically serves as a supply voltage supervisor. The CDGKT designation indicates a specific commercial grade variant within the TL7700 line, distinguished by its package type and reel configuration compared to other suffixes like DGKR or CPWR.

Supervisors Replacement Considerations

Consult official cross-reference lists for direct replacements such as TL7700CDGKR or TL7700CPWR. Verify pin-to-pin compatibility and electrical parameter equivalence before substitution.
