The TL7757CDR is a supply-voltage supervisor IC from Texas Instruments, engineered for use in microcomputer and microprocessor systems. It specifically monitors the supply voltage for undervoltage conditions, ensuring system stability during power fluctuations.
Key electrical specifications include a typical threshold voltage of 4.55V with an accuracy of 2.6%, and a low quiescent current of 1.4mA. The reset output is active-low and open-drain, and the device features a precision threshold voltage of 4.55V ±120mV. It also offers a high output sink capability of 20mA and a low standby current of 20µA.
The operating temperature range for the TL7757CDR is -40°C to 85°C. It is available in multiple package types, including SOIC (D), TO-92 (LP), and SOT-89 (PK). The device includes features like power-on reset generation and automatic reset generation after a voltage drop, preventing undefined operation during power-up or voltage sags.
This supervisor is suitable for applications requiring reliable monitoring of power supply rails, particularly in embedded systems where stable voltage is critical for proper operation. Its undervoltage monitoring capability helps protect sensitive components from damage due to low voltage conditions.
