Multi-voltage supervisor in a 5-pin SC-70
The MAX6740XKVHD7-T is a multi-voltage supervisor from Analog Devices, designed to monitor up to three supply rails and assert a reset signal when any monitored voltage falls below its threshold.
Three voltage thresholds and a 1.2-second reset timeout
The device monitors three voltages with thresholds at 1.313 V, 1.575 V, and an adjustable level — covering common core and I/O rails in mixed-voltage systems where a single supervisor IC replaces three discrete reset generators. A minimum reset timeout of 1.2 seconds gives the downstream processor time to initialize after the supply rails stabilize — long enough to cover most power-on ramp profiles in embedded systems.
