Product Summary

The MAX709CSA is a Power-Supply Monitor with Reset. The MAX709CSA provides a system reset during power-up, power-down, and brownout conditions. When VCC falls below the reset threshold, RESET goes low and holds the uP in reset for 140ms min after VCC rises above the threshold. The applications of the MAX709CSA are Minimum Component Count, Low-Cost Processor Systems.

Parametrics

MAX709CSA absolute maximum ratings: (1)Terminal Voltage (with respect to GND), VCC: -0.3V to 6.0V; RESET: -0.3V to (VCC + 0.3V); (2)Input Current, VCC: 20mA; (3)Output Current, RESET: 20mA; (4)Rate-of-Rise, VCC: 100V/μs; (5)Continuous Power Dissipation: 727mW; (6)Operating Temperature Ranges: 0 to +70℃; (7)Storage Temperature Range: -65 to +160℃; (8)Lead Temperature (soldering, 10sec): +300℃.
