MAX6337US23D3+T

The MAX6335/MAX6336/MAX6337 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. They also feature a debounced manual-reset input.These devices perform a single function: they assert a reset signal whenever the V_CCsupply voltage declines below a preset threshold or whenever manual reset is asserted. Reset remains asserted for a preset timeout period after V_CChas risen above the reset threshold or after manual reset is deasserted. The only difference among the three devices is their output. The MAX6336 (push/pull) and MAX6337 (open-drain) have an active-low RESET output, while the MAX6335 (push/pull) has an active-high RESET output. The MAX6335/MAX6336 are guaranteed to be in the correct state for V_CCdown to 0.7V. The MAX6337 is guaranteed to be in the correct state for V_CCdown to 1.0V.The reset comparator in these ICs is designed to ignore fast transients on V_CC. Reset thresholds are factory-trimmable between 1.6V and 2.5V, in approximately 100mV increments. There are 15 standard versions available (2500 piece minimum-order quantity); contact the factory for availability of nonstandard versions (10,000 piece minimum-order quantity). For space-critical applications, the MAX6335/MAX6336/MAX6337 come packaged in a 4-pin SOT143.
