Product details

What the MAX805LCPA is and where it fits

The MAX805LCPA monitors a single supply rail and switches to a backup battery when the main supply drops below 4.65 V. The active-high reset output holds the processor in reset for a minimum of 140 ms after the supply recovers.

Lifecycle and compliance

The MAX805LCPA is listed as Active in production. It is RoHS non-compliant (leaded solder finish). For RoHS-compliant builds, consider the MAX805LCPA+ (lead-free) variant.

Sourcing and availability

This part is sourced and quoted to order through independent distribution. Submit an RFQ for current pricing and availability.

Frequently asked questions

What is the reset timeout of MAX805LCPA?

The reset timeout is a minimum of 140 ms. This guarantees the processor is held in reset long enough for the supply and oscillator to stabilize after a power-up or brownout recovery.

Is MAX805LCPA RoHS compliant?

No, the MAX805LCPA is RoHS non-compliant. It uses a leaded solder finish. For RoHS-compliant builds, consider the MAX805LCPA+ (lead-free) variant.

What is the closest pin-compatible alternative to MAX805LCPA?

The MAX805LCPA is part of a family that includes the MAX807LCPA, which offers an adjustable threshold. Both share the same 8-DIP pinout and active-high reset output. The MAX807 allows you to set the trip voltage with an external resistor divider, while the MAX805 has a fixed 4.65 V threshold.

Where can I buy MAX805LCPA?

The MAX805LCPA is available to order through independent distribution. Submit an RFQ for current pricing and availability — lead times and stock levels are confirmed at quote time.
