The TL7757IDR IC has the following pin configuration:
___________
| |
NC |1 8| VCC
NC |2 7| RESET
GND|3 6| MR
NC |4 5| OUT
|___________|
The TL7757IDR operates by continuously monitoring the supply voltage using an internal precision voltage reference. When the voltage falls below the specified threshold, the IC generates a reset signal on the RESET pin. This reset signal remains active until the supply voltage rises above the threshold for the specified timeout period. The IC consumes low quiescent current during operation, making it suitable for power-sensitive applications.
The TL7757IDR is commonly used in various electronic systems where reliable voltage monitoring and reset generation are critical. Some application fields include:
These alternative models offer similar functionality and can be considered based on specific application requirements.
