TL7702ACDG4 - Brand New Texas Instruments Supervisors
-
Description
The TL7702ACDG4 is a voltage supervisor IC manufactured by Texas Instruments. It is designed to monitor the power supply voltage of a digital system and issue a reset signal when the voltage drops below a certain threshold. This helps to ensure that the system starts up in a known state and prevents it from operating with inadequate power. The TL7702ACDG4 is commonly used in applications such as microprocessors, microcontrollers, DSPs, and other digital systems where reliable power-on reset is critical for proper system operation.
Specifications and features
- Supply voltage range: 2.5V to 18V
- Reset threshold voltage: 4.55V to 4.85V (adjustable with external resistor)
- Reset timeout delay: 200ms to 560ms (adjustable with external capacitor)
- Active low push-pull reset output
- Low quiescent current: 45μA (typical)
- Operating temperature range: -40°C to +85°C
Application Scenarios
The TL7702ACDG4 can be used in a wide array of applications where reliable power-on reset is critical for system operation. Some common examples include:
- Microprocessors
- Microcontrollers
- DSPs
- FPGAs and CPLDs
- ASICs
- Automotive systems
- Industrial control systems
Comparison
Advantages- Adjustable reset threshold and timeout for flexibility in different applications
- Low quiescent current for power efficiency
Disadvantages- Requires external resistor and capacitor to set reset threshold and timeout
- Not suitable for applications with very low supply voltages (<2.5V)
