DATA SHEET www.onsemi.com 3-Pin Microprocessor Power Supply Supervisors CAT803, CAT809, CAT810 SOT−23 TB SUFFIX CASE 527AG 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.

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). 25 20 15 CAT809Z 10 CAT809M 5 0 1 10 100 1000 RESET OVERDRIVE VTH − VCC (mV) Figure 7.

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.
