9 / 20 page brownout conditions. RESET is guaranteed to be a logic low for 0V < VCC < VRST, provided VBATT is greater than 1V. Without a backup battery (VBATT = VCC = VOUT), RESET is guaranteed valid for VCC ≥ 1V. Once VCC exceeds the reset threshold, an internal timer keeps RESET low for the reset timeout period (tRP); after this interval, RESET becomes high imped- ance (Figure 2). RESET is an open-drain output, and requires a pull-up resistor to VCC (Figure 3). Use a 4.7k Ω to 1MΩ pull-up resistor that will provide sufficient current to assure the proper logic levels to the µP. If a brownout condition occurs (VCC dips below the reset threshold), RESET goes low. Each time RESET is asserted, it stays low for the reset timeout period. Any time VCC goes below the reset threshold, the internal timer restarts. The watchdog output (WDO) can also be used to initi- ate a reset. See the Watchdog Output section. The RESET output is the inverse of the RESET output, and it can both source and sink current. 3.0V/3.3V Adjustable Microprocessor Supervisory Circuits _______________________________________________________________________________________ 9 VCC VLOWLINE (MAX793/MAX794) VRESET (RESET PULLED UP TO VCC) VRESET (MAX793/MAX794) VCE OUT VWDO (MAX793/MAX794) VBOK (MAX793) VPFO (MAX793/MAX794) SHOWN FOR VCC = 3.3V to 0V, VBATT = 3.6V, CE IN = GND, PFI = VCC.
