Frequently Asked Questions
What supply voltage does the TL7705A monitor?
The TL7705A is designed to monitor a 5V supply rail, with an internal threshold of approximately 4.55V. When the supply drops below this level, it asserts a reset signal to protect the connected microprocessor or system logic.
How is the time delay programmed in the TL7705A?
The reset time delay of the TL7705A is programmed by connecting an external capacitor to the CT pin. A larger capacitor increases the delay, giving the power supply more time to stabilize before the reset is released.
What type of reset output does the TL7705A provide?
The TL7705A provides an active-low reset output that is asserted when the monitored supply voltage falls below the 4.55V threshold, and is released after the programmed time delay once the supply recovers.
What package is the TL7705A available in?
The TL7705A is available in a standard DIP (Dual-In-Line Package), which supports through-hole PCB assembly and is compatible with standard 14-pin or 8-pin DIP sockets commonly used in prototyping and production boards.
