产品概述

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. The MAX6332/MAX6333 are guaranteed to be in the correct state for VCC down to 0.7V. The MAX6334 is guaranteed to be in the correct state for VCC down to 1.0V.

The reset comparator in these ICs is designed to ignore fast transients on VCC. Reset thresholds are factory-trimmable between 1.6V and 2.5V, in approximately 100mV increments. There are 15 standard versions available (2,500 piece minimum-order quantity); contact the factory for availability of nonstandard versions (10,000 piece minimum-order quantity). For space-critical applications, the MAX6332/MAX6333/MAX6334 come packaged in a 3-pin SOT23.
