FAQs

What is TL7700CDGKR?

The TL7700CDGKR is a supply voltage supervisor and watchdog timer designed by Texas Instruments. It is used to monitor the power supply voltage of a system and provide reset signals to the microcontroller or other ICs in the event of a power supply failure or voltage drop.

How Does TL7700CDGKR Work?

The TL7700CDGKR works by continuously monitoring the voltage level of the power supply. If the voltage falls below a preset threshold, the TL7700CDGKR generates a reset signal to the connected microcontroller, allowing the system to reset or enter a safe state. Additionally, the watchdog timer feature allows the TL7700CDGKR to monitor the activity of the microcontroller and reset the system if it becomes non-responsive.

How Many Pins does TL7700CDGKR have and What are the Functions of the Pinout Configuration?

The TL7700CDGKR is housed in an 8-pin VSSOP (Very Small Outline Package) package. The pinout configuration includes:

RESET: Open-drain reset output.
MR: Manual reset input for external reset control.
VDD: System power supply input.
GND: Ground connection.
VIT: Voltage input to monitor.
CT: Time delay setting pin for reset pulse duration.
MRG: Master reset gating input.
WDI: Watchdog input to detect microcontroller activity.

What are the Pros and Cons of TL7700CDGKR?

Pros:

Supply Voltage Monitoring: Ensures safe operation by monitoring the power supply voltage.
Manual Reset Input: Allows for external reset control if needed.
Watchdog Timer: Provides an additional layer of system security by monitoring microcontroller activity.
Small Package: The VSSOP package is space-efficient, suitable for space-constrained designs.

Cons:

Additional Components: May require additional external components for tailored functionality.
Configuration Complexity: Requires careful consideration of voltage levels and time delay settings for proper operation.

Are There Any Equivalents/Alternatives to TL7700CDGKR for Recommendation?

Equivalents to the TL7700CDGKR include the MAX809 from Maxim Integrated and the ADM1232 from Analog Devices.
Alternatives to the TL7700CDGKR include the TPS3808 from Texas Instruments and the MCP809 from Microchip Technology.
