Four-channel supervisor for multi-rail systems
The MAX16060ETE+ from Analog Devices (formerly Maxim Integrated) is a multi-voltage supervisor that monitors up to four supply voltages simultaneously. It asserts an active-low reset output when any monitored voltage falls below its threshold, and holds reset for a minimum of 140 ms after all rails recover, with an option to extend the timeout via an external capacitor. The open-drain output allows wired-OR connection to other reset sources. Housed in a 16-pin TQFN package with an exposed pad (4x4 mm), it operates over the full -40 to 125°C temperature range, making it suitable for industrial, automotive, and telecom power-rail sequencing and fault detection.
Active production, no obsolescence risk
The MAX16060ETE+ carries an active lifecycle status and is ROHS3 compliant.
Package and mounting
Threshold voltages are set via external resistor dividers, giving the designer flexibility to monitor non-standard rail voltages (e.g., 1.2 V, 2.5 V, 3.3 V, 5 V) without being locked to fixed factory-trimmed levels. The reset timeout defaults to 140 ms, which covers most power-supply ramp and oscillator start-up sequences; adding a capacitor to the CT pin extends it proportionally. For a system with a slow-start power module or a large bulk capacitance, plan the timeout margin so the supervisor does not falsely hold the system in reset while the rails are still settling.
