Description
The MAX6453-MAX6456 are low-power, dual-voltage µP supervisors featuring separate VCC reset and manual reset outputs. The dual outputs support both soft-system reset (interrupt) and hard-system reset (reboot) functions. The reset output asserts when any of the monitored voltages falls below its specified threshold and remains asserted for the reset timeout (140ms min) after all voltages exceed their respective reset thresholds. All devices are offered with nine factory-fixed reset thresholds for monitoring primary system voltages (VCC) from 1.8V to 5V and an adjustable reset input for monitoring a secondary system voltage down to 0.63V.

Each device has a manual reset input, a VCC reset output, and a manual reset output. The MAX6453/MAX6454 manual reset output asserts when the manual reset input is low. It remains asserted for the manual reset timeout period (140ms min) after the manual reset input transitions high. The MAX6453/MAX6354 manual reset input controls only the manual reset output and does not affect the VCC reset output.

The manual reset input of the MAX6455/MAX6456 controls both the manual reset and VCC reset outputs. When the manual reset input is low for less than 3.3s (typ), only the manual reset output asserts and remains asserted for the manual reset timeout period (140ms min) after the manual reset input transitions high. If the manual reset input is low for at least 3.3s (typ), the reset output also asserts and remains asserted for the reset timeout period (140ms min) after the manual reset input transitions high. This enhanced feature allows the implementation of a soft/hard-system reset combination.

The MAX6453/MAX6455 have active-low push-pull reset and manual reset outputs, and the MAX6454/MAX6456 have active-low open-drain reset and manual reset outputs. All devices are available in small SOT23-6 packages and are fully specified over the extended temperature range (-40°C to +85°C).
