description

The TL7757 is a monolithic supply voltage supervisor designed for use in microcomputer and microprocessor systems. The supervisor monitors the supply voltage for undervoltage conditions. During power up, when the supply voltage, V_CC, attains a value approaching 1 V, the RESET\ output becomes active (low) to prevent undefined operation. If at any time, the supply voltage drops below threshold voltage level (V_IT-), the RESET \output goes to the active (low) level until the supply undervoltage fault condition is eliminated.

The C-suffix device is characterized for operation from 0°C to 70°C. The I-suffix device is characterized for operation from -40°C to 85°C. The M-suffix device is characterized for operation from -55°C to 125°C.
