1 / 9 page © Semiconductor Components Industries, LLC, 2012 October, 2012 − Rev. 2 1 Publication Order Number: CAT811/D CAT811, CAT812 4-Pin Microprocessor Power Supply Supervisors with Manual Reset Description The CAT811 and CAT812 are microprocessor supervisory circuits that monitor power supplies. The CAT811 and CAT812 are direct replacements for the MAX811 and MAX812 in applications operating over the industrial temperature range; both have a manual reset input. These devices generate a reset signal, which is asserted while the power supply voltage is below a preset threshold level and for at least 140 ms after the power supply level has risen above that level. The underlying floating gate technology, Analog EEPROM used by ON Semiconductor, makes it possible to offer any custom reset threshold value. Seven industry standard threshold levels are offered to support +5.0 V, +3.3 V, +3.0 V and +2.5 V systems. The CAT811 features a RESET push−pull output (active LOW) and the CAT812 features a RESET push−pull output (active HIGH). Fast transients on the power supply are ignored and the output is guaranteed to be in the correct state at Vcc levels as low as 1.0 V. The CAT811/812 are fully specified over the industrial temperature range (−40 °C to 85°C) and are available in a compact 4−pin SOT−143 package. Features • Precision Monitoring of +5.0 V ( ± 5%, ± 10%, ± 20%), +3.3 V ( ± 5%, ± 10%), +3.0 V ( ± 10%) and +2.5 V ( ± 5%) Power Supplies • Manual Reset Input • Offered in Two Output Configurations: CAT811: Active LOW Reset CAT812: Active HIGH Reset • Direct Replacements for the MAX811 and MAX812 in Applications Operating over the Industrial Temperature Range • Reset Valid down to VCC = 1.0 V • 6 mA Power Supply Current • Power Supply Transient Immunity • Available in SOT−143 Packages with Sn or NiPdAu Green Lead Finishes • Industrial Temperature Range: −40°C to +85°C • These Devices are Pb−Free, Halogen Free/BFR Free and are RoHS Compliant Applications • Computers, Servers, Laptops and Cable Modems • Wireless Communications • Embedded Control Systems • White Goods, Power Meters • Intelligent Instruments • PDAs and Handheld Equipment http://onsemi.com PIN CONFIGURATION See detailed ordering and shipping information in the package dimensions section on page 9 of this data sheet.
