MAX700

The MAX700 are supervisory circuits used to monitor the power supplies in P and digital systems. The RESET/RESET outputs of the MA)(700/701/702 are guaranteed to be in the correct state for Voo voltages down to (Figure They provide excellent circuit reliability arid low cost by eliminating external components and adjustments when used with powered circuits. The is the simplest part in the family. When VCC falls to 4.65V RESET goes low. The also provides a debounced manual reset input. The performs the same functions but has both RESET and RESET outputs. Their primary function is to provide a system reset. Accordingly, an active reset signal is supplied for low supply voltages and for at least 200ms after the supply voltage reaches its operating value. ln addition to the features of the MAX701 and MAX702. The MAX700 provides preset or adjustable voltage detection so threshords other than 4.65V can be selected, and adjustable hysteresis. All parts are supplied in Plastic DIP and Narrow SO packages in commercial and extended temperature ranges.

The features of MAX700 can be summarized as (1)min 200ms RESET pulse on power-up, power-down, and during low-voltage conditions; (2)reset threshold factory trimmed for systems; (3)no external components or adjustments with +5 V powered circults; (4)debounced manual reset input; (5)preset or adjustable voltage detection (MAX700); (6)adjustable hysteresis (MAX700); (7)8-pin plastic DIP and Narrow SO packages.

The absolute maximum ratings of MAX700 are (1)VCC: -0.3V to +15.5V; (2)voltage (with respect to GND) at RESET, RESET. HYST, CTL. SENSE: -0.3V to VCC; (3)operating temperawre range: MAX70_C: 0 to +70°C; MAX70_E: -40°C to +85°C; (4)rate rise. VCC: 100V/s; (5)power dissipat any package: 380mW; (6)storage temperature range: -65°C to +150°C; (7)lead temperature (soldewg. 10 sec.): 300°C.
