The TL7757CLPG4 is a Supply-voltage Supervisor and Precision Voltage Detector with active-low open-drain output. It is designed for use in microcomputer and microprocessor systems. The supervisor monitors the supply voltage for under-voltage conditions. During power-up, when the supply voltage, VCC, attains a value approaching 1V, the /RESET output becomes active (low) to prevent undefined operation. If the supply voltage drops below threshold voltage level (VIT-), the /RESET output goes to the active (low) level until the supply under-voltage fault condition is eliminated.
- power-ON reset generator
- Automatic reset generation after voltage drop
- Comparator hysteresis prevents erratic reset
- /RESET output defined when VCC exceeds 1V
- 20μA Low standby current
- 20mA High output sink capability
