+5V, Low-Power µP Supervisory Circuits with Adjustable Reset/Watchdog
_______________General Description
The MAX6301/MAX6302/MAX6303/MAX6304* lowpower microprocessor (µP) supervisory circuits provide maximum adjustability for reset and watchdog functions. The reset threshold can be adjusted to any voltage above 1.22V, using external resistors. In addition, the reset and watchdog timeout periods are adjustable using external capacitors. A watchdog select pin extends the watchdog timeout period to 500x. The reset function features immunity to power-supply transients. These four devices differ only in the structure of their reset outputs (see Selector Guide). The MAX6301–MAX6304 are available in the space-saving 8-pin µMAX package, as well as 8-pin DIP/SO.

FEATURES
• ESD Protection for RS-232 Bus Pins – ±15-kV – Human-Body Model
• Meets or Exceeds the Requirements of TIA/EIA-232-F and ITU v.28 Standards
(2) All voltages are with respect to network GND. (3) Maximum power dissipation is a function of TJ(max), θJA, and TA. The maximum allowable power dissipation at any allowable ambient
temperature is PD = (TJ(max) – TA)/θJA. Operating at the absolute maximum TJ of 150°C can affect reliability. (4) The package thermal impedance is calculated in accordance with JESD 51-7.
