Product Summary

The MAX705MJA microprocessor (μP) supervisory circuit reduces the complexity and number of components required to monitor power-supply and battery functions in μP systems. The device significantly improve system reliability and accuracy compared to separate ICs or discrete components. Two supply-voltage monitor levels are available: The MAX705MJA generates a reset pulse when the supply voltage drops below 4.65V. The MAX705MJA is available in 8-pin DIP, SO and μMAX packages.

Parametrics

MAX705MJA absolute maximum ratings: (1)Terminal Voltage (with respect to GND), VCC: -0.3V to 6.0V; (2)All Other Inputs: -0.3V to (VCC + 0.3V); (3)Input Current, VCC: 20mA; GND: 20mA; (4)Output Current (all outputs): 20mA; (5)Continuous Power Dissipation, Plastic DIP (derate 9.09mW/℃ above +70℃): 727mW; (6)Operating Temperature Ranges: 0℃ to +70℃; (7)Storage Temperature Range: -65℃ to +160℃; (8)Lead Temperature (soldering, 10sec): +300℃.
