Product details

2-channel supervisor with dual-threshold monitoring

The DS1834AS+ is a multi-voltage supervisor from the EconoReset series, monitoring two supply rails with thresholds at 3.3V and 5V. It asserts a reset output when either monitored voltage drops below its threshold, holding the reset active for a minimum of 200ms after all voltages return to tolerance. The reset output is active-low, open-drain, which allows multiple supervisors to share a common pull-up resistor and wired-OR connection to the system reset line.

Industrial temperature range and SOIC footprint

The supply voltage range is implicit from the monitored thresholds — the device must be powered from a rail above the highest threshold (5V) to operate correctly. Typical VCC is 5V ±10%.

Active production, RoHS3 compliant

Sourced through authorized and independent distribution channels.

Frequently asked questions

How can I order the DS1834AS+ or check availability?

The DS1834AS+ is an active-production part from Analog Devices. Submit an RFQ with your target quantity; we confirm availability and current pricing through our distribution network at quote time.

What voltages does the DS1834AS+ monitor?

It monitors two voltages with thresholds at 3.3V and 5V. The reset output asserts when either rail falls below its threshold.

What is the reset timeout of the DS1834AS+?

The reset timeout is a minimum of 200ms after all monitored voltages rise above their thresholds.

Is the DS1834AS+ RoHS compliant?

Yes, it is RoHS3 compliant (ROHS3 Compliant per the manufacturer's listing).
