CAT8801STB-GT3 ON Semiconductor

CAT8801 200 nA Microprocessor Power Supply Supervisors Description The CAT8801 is a supervisory circuit that monitors power supplies in digital systems and provides a reset signal whenever the systems CAT8801 Table 1. PIN DESCRIPTION Pin Name Description 1 GND Ground 2 RESET Active LOW reset. RESET is asserted if V falls below the reset threshold and remains low for at least CC 140 ms after V rises above the reset threshold. CC 3 V Power supply voltage that is monitored. CC Block Diagram V CC V CC V TOLERANCE + CC DIGITAL BIAS RESET DELAY VOLTAGE REFERENCE CAT8801 GND Table 2. 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 mW Derate 2.2 mW/C above 70C (SC70) 175 Derate 4 mW/C above 70C (SOT23) 320 Operating Temperature Range 40 to +85 C Storage Temperature Range 65 to +150 C Lead Soldering Temperature (10 seconds) 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.
