MAX6421XS29+T

The MAX6421XS29+T is a low power microprocessor (μP) reset circuit with capacitor adjustable reset timeout delay in 4 pin SC-70 package. This supervisor circuit monitors system voltages from 1.6V to 5V. The device performs a single function that is it asserts a reset signal whenever the VCC supply voltage falls below its reset threshold. The reset output remains asserted for the reset timeout period after VCC rises above the reset threshold. The reset timeout is externally set by a capacitor to provide more flexibility. The MAX6421 has an active-low, push-pull reset output. It is typically used in battery powered computers/controllers, intelligent instruments and embedded controllers.

• Supply voltage range from 1V to 5.5V
• Operating temperature range from -40°C to 125°C
• Low quiescent current of 1.6μA (VCC ≤ 2V)
• Reset valid to VCC = 1V
• Immune to short VCC transients
• Reset threshold voltage of 2.925V
• Reset timeout period of 4.375ms (CSRT = 1500pF)
