GENERAL DESCRIPTION The ADM803/ADM809/ADM810 supervisory circuits monitor the power supply voltage in microprocessor systems. They provide a reset output during power-up, power-down, and brownout conditions. On power-up, an internal timer holds reset asserted for 240 ms. This holds the microprocessor in a reset state until conditions have stabilized. The reset output remains operational with VCC as low as 1 V. The ADM803 and ADM809 provide an active low reset signal (RESET), whereas the ADM810 provides an active high signal (RESET) output. The ADM809 and ADM810 have push-pull outputs, whereas the ADM803 has an open-drain output, which requires an external pull-up resistor. Rev. I Seven reset threshold voltage options are available, suitable for monitoring a variety of supply voltages (see Table 3). The reset comparator features built-in glitch immunity, making it immune to fast transients on VCC. The ADM803/ADM809/ADM810 consume only 17 A, making them suitable for low power, portable equipment. The ADM803 is available in a 3-lead SC70; the ADM809/ADM810 are available in 3-lead SOT-23 and 3-lead SC70 packages.

I | Page 7 of 11 ADM803/ADM809/ADM810 Data Sheet INTERFACING TO OTHER DEVICES The ADM803/ADM809/ADM810 series is designed to integrate with as many devices as possible and, therefore, has a standard output dependent on VCC. This enables the parts to be used in both 3 V and 5 V, or any nominal voltage within the minimum and maximum specifications for VCC. This design simplifies interfacing the ADM803/ADM809/ADM810 to other devices. ENSURING A VALID RESET OUTPUT DOWN TO VCC = 0 V When VCC falls below 0.8 V, the ADM803/ADM809 RESET no longer sinks current. A high impedance CMOS logic input connected to RESET may, therefore, drift to undetermined logic levels. To eliminate this problem, a 100 k resistor should be connected from RESET to ground. VCC ADM803/ADM809/ADM810, the possibility of a malfunction during a power failure is greatly reduced because the devices can operate effectively even when there are large degradations of the supply voltages. Another advantage is the very accurate internal voltage reference circuit of the ADM803/ADM809/ ADM810. These benefits combine to produce an exceptionally reliable voltage monitor circuit. INTERFACING TO MICROPROCESSORS WITH MULTIPLE INTERRUPTS In a number of cases, it is necessary to interface many interrupts from different devices (for example, thermal, altitude, and velocity sensors). The ADM803/ADM809/ADM810 can easily be integrated into existing interrupt-handling circuits, as shown in Figure 13, or can be used as standalone devices.

Ensuring a Valid Reset Output Down to VCC = 0 V GND 03736-012 BENEFITS OF AN ACCURATE RESET THRESHOLD In other microprocessors, tolerances in supply voltages lead to an overall increase in reset tolerance levels due to the deterioration of the reset circuit's power supply.
