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 VCC 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. • • • • • • SC−70 SD SUFFIX CASE 419AB PIN CONFIGURATION 3−Lead SOT23 3−Lead SC70 GND • Precision Monitoring of • SOT−23 TB SUFFIX CASE 527AG 1 Features • http://onsemi.com +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 VCC = 1.0 V 6 mA 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 3 VCC 2 RESET (RESET) (Top View) CAT803 CAT809 (CAT810) MARKING DIAGRAMS XXXMG G XXXMG G SOT−23 SC−70 XXX M G = Specific Device Code = Month Code = Pb−Free Package (*Note: Microdot may be in either location) Applications • • • • • • Computers, Servers, Laptops, Cable Modems Wireless Communications Embedded Control Systems White Goods, Power Meters Intelligent Instruments PDAs and Handheld Equipment © Semiconductor Components Industries, LLC, 2014 August, 2014 − Rev. 34 ORDERING INFORMATION See detailed ordering and shipping information in the package dimensions section on page 8 of this data sheet. 1 Publication Order Number: CAT803/D CAT803, CAT809, CAT810 Table 1.

Reset Timing Diagram 30 VCC Transient Response The CAT803/CAT809/CAT810 protect mPs against brownout failure. Short duration transients of 4 msec or less and 100 mV amplitude typically do not cause a false RESET. Figure 7 shows the maximum pulse duration of negative− going VCC transients that do not cause a reset condition. As the amplitude of the transient goes further below the threshold (increasing VTH − VCC), the maximum pulse duration decreases. In this test, the VCC starts from an initial voltage of 0.5 V above the threshold and drops below it by the amplitude of the overdrive voltage (VTH − VCC).

For the CAT810, a pull−up resistor from RESET pin to VCC is needed. Power Supply Power Supply VCC VCC 10 kW CAT810 CAT809 RESET RESET 10 kW GND GND Figure 8.

RESET Valid with VCC Under 1.1 V Bi−directional Reset Pin Interfacing The CAT809/810 can interface with mP/mC bi−directional reset pins by connecting a 4.7 kW resistor in series with the CAT809/810 reset output and the mP/mC bi−directional reset pin.

Bi−directional Reset Pin Interfacing CAT803 Open−Drain RESET Application Power Supply The CAT803 features an open−drain RESET output and therefore needs a pull−up resistor on the output for proper operation, as shown on Figure 11. An advantage of the open−drain output includes the ability to “wire AND” several outputs together to form an inexpensive logic circuit. It is also possible to have the pull−up resistor connected to a different supply which can be higher than the CAT803 VCC pin. The value of the pull−up resistor is not critical in most applications, typical values being between 5 kW and 10 kW. VCC 5 kW CAT803 VCC mP RESET GND RESET INPUT GND Figure 11.
