MAX6443US31L+T

The MAX6443US31L+T is a μP reset circuit with long manual reset setup period in 4 pin SOT-143 package. It is a low-current microprocessor reset circuit features single manual reset inputs with an extended setup period. Because of the extended setup period, short switch closures (nuisance resets) are ignored. The reset output asserts when any of the monitored supply voltages drops below its specified threshold. The reset output remains asserted for the reset timeout period (210ms typ) after all monitored supplies exceeds their reset thresholds. The reset output is one-shot pulse asserted for the reset timeout period (140ms min) when selected manual reset input(s) are held low for an extended setup timeout period. This device ignores manual reset transitions of less than the extended setup timeout period.

• Supply voltage range is 1V to 5.5V
• Operating temperature range from -40°C to 85°C
• VCC nominal voltage threshold voltage is 3.075V
• Manual reset setup period is 6.72s
• Immune to short voltage transients
• Valid reset down to VCC = 1.0V
• Low 6μA supply current
• Push pull reset
