The TL7757CPK from Dallas Semiconductor is a supply-voltage supervisor and precision voltage detector. It is designed to monitor the supply voltage for undervoltage conditions in microcomputer and microprocessor systems.
Key electrical specifications include a typical threshold voltage of 4.55V with an accuracy of 2.6%. The quiescent current is typically 1.4mA, with a low standby current of 20µA. The reset output is active-low and open-drain, becoming active (low) when the supply voltage VCC drops below the threshold or during power-up when VCC approaches 1V. It features a high output sink capability of 20mA and comparator hysteresis to prevent erratic resets.
The device operates within a temperature range of -40°C to 85°C. It monitors a single supply voltage. Available package types include SOIC (D), TO-92 (LP), and SOT-89 (PK).
This supervisor is suitable for applications requiring reliable power-on reset and undervoltage monitoring.
