Frequently Asked Questions
What is the operating voltage range of the TL7700CPSR?
The TL7700CPSR operates from a supply voltage range of 3V to 18V, making it compatible with both 3.3V and 5V logic systems. The adjustable threshold allows the user to set the reset trip point using an external resistor divider network.
How is the reset threshold voltage set on the TL7700CPSR?
The reset threshold is programmed by connecting an external resistor voltage divider to the CT/R pin. This allows flexible system design where the supervisor can monitor a wide range of supply rails from 1.2V to 18V depending on the resistor ratio selected.
What package is the TL7700CPSR available in and what are its dimensions?
The TL7700CPSR comes in an 8-pin Small Outline IC (SOIC) package, also identified by JESD-30 code R-PDSO-G8. The small outline package measures approximately 5mm x 4mm, ideal for space-constrained PCB designs. It is RoHS compliant (Pb-free).
Can the TL7700CPSR be used as a brown-out detector?
Yes, the TL7700CPSR functions as a brown-out detector by monitoring the supply voltage and asserting the active-low reset output when the voltage drops below the programmed threshold. This ensures microcontrollers and processors are held in reset during power supply dips, preventing data corruption or undefined behavior.
