MAX6355TYUK-T - Maxim Integrated Products - Dual/Triple-Voltage μP Supervisory Circuits

Quick Detail:

Dual/Triple-Voltage Î¼P Supervisory Circuits

Description:

The MAX6351–MAX6360 microprocessor (µP) supervisors with multiple reset voltages significantly improve system reliability and accuracy compared to separate ICs or discrete components. If any input supply voltage drops below its associated preset threshold, all reset outputs are asserted. In addition, the output(s) is valid as long as either input supply voltage remains greater than +1.0V.

All devices in this series have an active-low debounced manual reset input. In addition, the MAX6358/MAX6359/MAX6360 offer a watchdog timer input with a 46.4sec start-up timeout period and a 2.9sec timeout period.

The MAX6355/MAX6356/MAX6357 offer an additional voltage monitor input to monitor a third voltage.

The MAX6351 features both 3V and 5V active-low pushpull reset outputs. The MAX6353/MAX6356/MAX6359 offer a 5V active-low push-pull reset. The MAX6354/MAX6357/MAX6360 offer a 3V active-low push-pull reset. The MAX6352/MAX6355/MAX6358’s reset is active-low open-drain.

All of these devices are offered with a wide variety of voltage threshold levels, as shown in the Voltage

Threshold Levels table below. They are available in 5- and 6-pin SOT23 packages and operate over the extended (-40°C to +85°C) temperature range.
