Product Summary

The MAX706ESA is a low-cost, up supervisory circuit. The MAX706ESA reduces the complexity and number of components required to monitor power-supply and battery functions in μP systems. These devices significantly improve system reliability and accuracy compared to separate ICs or discrete components. The MAX707/MAX708 are the same as the MAX706ESA, except an active-high reset is substituted for the watchdog timer. The MAX813L is the same as the MAX705, except RESET is provided instead of RESET. Two supply-voltage monitor levels are available: The MAX705/MAX707/MAX813L generate a reset pulse when the supply voltage drops below 4.65V, while the MAX706ESA+T generates a reset pulse below 4.40V. All four parts are available in 8-pin DIP, SO and μMAX packages.

Parametrics

MAX706ESA absolute maximum ratings: (1)Terminal Voltage (with respect to GND)VCC: -0.3V to 6.0V; (2)Terminal Voltage (with respect to GND)All Other Inputs (Note 1): -0.3V to (VCC + 0.3V); (3)Input Current VCC: 20mA; (4)Input Current GND: 20mA; (5)Output Current (all outputs): 20mA; (6)Continuous Power Dissipation; (7)Plastic DIP (derate 9.09mW/°C above +70°C): 727mW; (8)Storage Temperature Range: -65°C to +160°C; (9)Lead Temperature (soldering, 10sec): +300°C.

Features

MAX706ESA features: (1)μMAX Package: Smallest 8-Pin SO; (2)Guaranteed RESET Valid at VCC = 1V; (3)Precision Supply-Voltage Monitor: 4.65V in MAX705/MAX707/MAX813L, 4.40V in MAX706/MAX708; (4)200ms Reset Pulse Width; (5)Debounced TTL/CMOS-Compatible Manual-Reset Input; (6)Independent Watchdog Timer—1.6sec Timeout (MAX705/MAX706); (7)Active-High Reset Output (MAX707/MAX708/MAX813L); (8)Voltage Monitor for Power-Fail or Low-Battery Warning.
