The MAX6426UK29+T is a compact, highly reliable microprocessor (µP) supervisory circuit designed and manufactured by Maxim Integrated. This device is engineered to monitor power supplies in µP and digital systems, providing a robust level of protection against low voltage, which is critical for maintaining system integrity.

With its precision factory-set V<sub>CC reset threshold of 2.925V, the MAX6426UK29+T ensures that your system will reset accurately and reliably. It is ideal for portable and battery-powered equipment, such as PDAs, handheld instruments, and mobile communication devices, where power conservation is paramount.

The reset output stage of the MAX6426UK29+T is available in both push-pull and open-drain configurations, providing versatility in reset signal delivery. This device has an active-low RESET output, which remains asserted for a minimum reset timeout period of 140ms after V<sub>CC rises above the reset threshold level. This feature ensures that the µP has sufficient time to stabilize before resuming operation.

Packaged in a space-saving 5-pin SOT23, the MAX6426UK29+T is designed for space-constrained applications. This tiny package, combined with its low supply current of 1.2µA, makes it an excellent choice for portable designs where efficiency and board space are at a premium.

Key features of the MAX6426UK29+T include:

• Precision V<sub>CC Reset Threshold of 2.925V
• Low 1.2µA Supply Current
• 140ms Minimum Reset Timeout Period
• Immune to Short V<sub>CC Transients
• Available in Push-Pull or Open-Drain RESET Output
• Compact 5-Pin SOT23 Package

Maxim Integrated's commitment to quality and reliability is evident in the MAX6426UK29+T, making it a trusted choice for safeguarding your digital systems against the dangers of inadequate power supply.
