? semiconductor components industries, llc, 2012 october, 2012 ? rev. 33 1 publication order number: cat803/d cat803, cat809, cat810 3-pin microprocessor power supply supervisors description the cat803, cat809, and cat810 are supervisory circuits that monitor power supplies in digital systems. the cat803, cat809, and cat810 are direct replacements for the max803, max809 and max810 in applications operating over the industrial temperature range. 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 cat803 has an open ? drain reset output (active low). the cat803 requires a pull ? up resistor on the reset output. the cat809 features a push ? pull reset output (active low) and the cat810 features a push ? pull reset output (active high). fast transients on the power supply are ignored and the output is guaranteed to be in the correct state at v cc levels as low as 1.0 v. the cat803, cat809, and cat810 are available in both the compact 3 ? pin sot ? 23 and sc ? 70 packages. 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 ? offered in three output configurations: ? cat803: open ? drain active low reset ? cat809: push ? pull active low reset ? cat810: push ? pull active high reset ? direct replacements for the max803, max809 and max810 in applications operating over the industrial temperature range ? reset valid down to v cc = 1.0 v ? 6 a power supply current ? power supply transient immunity ? industrial temperature range: ? 40 c to +85 c ? available in sot ? 23 and sc ? 70 packages ? these devices are pb ? free and are rohs compliant applications ? computers, servers, laptops, cable modems ? wireless communications ? embedded control systems ? white goods, power meters ? intelligent instruments ? pdas and handheld equipment http://onsemi.com pin configuration v cc reset (reset) gnd 1 see detailed ordering and shipping information in the package dimensions sect ion on page 8 of this data sheet. ordering information (top view) sot ? 23 tb suffix case 527ag sc ? 70 sd suffix case 419ab 2 3 cat803 cat809 (cat810) 3 ? lead sot23 3 ? lead sc70 xxxm xxx = specific device code m = month code = pb ? free package xxxm marking diagrams (*note: microdot may be in either location) sot ? 23 sc ? 70
