Product details

Three-voltage supervisor in a small SOT-23-8 footprint

The MAX6701TKA monitors three voltage rails: one fixed threshold at 3.08V and two adjustable thresholds set by external resistor dividers.

Voltage thresholds and adjustable monitoring

The fixed 3.08V threshold monitors a 3.3V rail. The two adjustable inputs track a second core voltage and an I/O or auxiliary rail.

Reset behaviour and timing

The active-low reset asserts immediately when any monitored voltage drops below its threshold and stays asserted for a minimum of 120ms after all voltages rise above threshold. That 120ms window is long enough for most switching regulators to reach regulation and for oscillator start-up transients to settle. The push-pull output drives CMOS logic inputs directly without an external pull-up, saving one resistor per reset line.

It is listed as RoHS non-compliant, so verify your BOM's regulatory requirements before committing — if your assembly line or end-market requires RoHS conformity, this part will need an exemption or a compliant alternative.

Frequently asked questions

Is MAX6701TKA RoHS compliant?

No, the MAX6701TKA is listed as RoHS non-compliant. If your BOM requires RoHS conformity, you will need an exemption or a compliant alternative — check with your assembly house whether they accept non-RoHS parts under a customer-directed waiver.

What is the closest pin-compatible alternative to MAX6701TKA in this component family?

The MAX6700 is the closest sibling in the same family. Both are three-voltage supervisors in SOT-23-8 with active-low reset and push-pull output. The key difference is the fixed threshold voltage: the MAX6701TKA monitors 3.08V on the fixed channel, while the MAX6700 uses a different fixed threshold. Verify the threshold match against your monitored rail before substituting.

What is MAX6701TKA's listed type (Power Supply Monitor) on this component line?

The MAX6701TKA is a Power Supply Monitor — a voltage supervisor that monitors up to three supply rails and asserts a reset signal when any rail falls below its threshold. It is not a regulator or a sequencer; it only monitors and reports.

What is MAX6701TKA's listed reset (Active Low) on this component line?

The reset output is active-low, meaning the reset signal goes low (asserted) when a monitored voltage is out of tolerance, and goes high (de-asserted) after the 120ms timeout once all voltages are good. This is the standard polarity for most MCU reset inputs.
