The TL7757CPK from Texas Instruments is a dedicated supply voltage supervisor IC. It is engineered to monitor a single supply voltage for undervoltage conditions, crucial for the stable operation of microcomputer and microprocessor systems.
Key electrical characteristics include a typical threshold voltage of 4.55V with an accuracy of 2.6%. The device features an active-low, open-drain reset output, which becomes active (low) when the supply voltage drops below the threshold. It also provides a power-on reset function, ensuring the system starts in a defined state when VCC exceeds 1V.
This supervisor IC operates within a temperature range of -40°C to 85°C and has a low quiescent current of 1.4mA. The SOT-89-3 package is suitable for surface mounting, making it adaptable for various PCB designs.
Features like comparator hysteresis prevent erratic resets, and a high output sink capability of 20mA is provided. The TL7757CPK is designed to protect systems from voltage drops and power-on glitches, contributing to overall system reliability.
