19-1411; Rev 0; 12/98 3-Pin, Ultra-Low-Voltage, Low-Power µP Reset Circuits General Description The MAX6332/MAX6333/MAX6334 microprocessor (µP) supervisory circuits monitor the power supplies in 1.8V to 3.3V µP and digital systems. They increase circuit reliability and reduce cost by eliminating external components and adjustments. These devices perform a single function: they assert a reset signal whenever the VCC supply voltage declines below a preset threshold, keeping it asserted for a preset timeout period after VCC has risen above the reset threshold. The only difference among the three devices is their output. The MAX6333 (push/pull) and MAX6334 (open-drain) have an active-low RESET output, while the MAX6332 (push/pull) has an active-high RESET output.
