CAT853, CAT859, CAT863, CAT869 3-Pin Microprocessor Power Supply Supervisors Description The CAT853, CAT863, CAT859, and CAT869 are supervisory CAT853, CAT859, CAT863, CAT869 Table 2. PIN DESCRIPTION Pin Name Function RESET Active low reset. RESET is asserted if V falls below the reset threshold and remains low for at least 140 ms after CC V rises above the reset threshold CC GND Ground V Power supply voltage that is monitored CC V CC V CC V TOLERANCE + CC RESET DIGITAL BIAS DELAY VOLTAGE REFERENCE CAT853 CAT863 GND V CC V CC TOLERANCE + V CC DIGITAL BIAS RESET DELAY VOLTAGE CAT859 REFERENCE CAT869 GND Figure 1.

ABSOLUTE MAXIMUM RATINGS Parameters Ratings Units Any pin with respect to ground 0.3 to +6.0 V Input Current, V 20 mA CC Output Current, RESET 20 mA Rate of Rise, V 100 V/ s CC Continuous Power Dissipation 320 mW Derate 4 mW/C above 70C (SOT23) Operating Temperature Range 40 to +85 C Storage Temperature Range 65 to +105 C Lead Soldering Temperature (10 sec) 300 C Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect device reliability.
