5-channel voltage supervisor in a 16-pin DIP
The MAX8214AEPE is a multi-voltage supervisor from Analog Devices that monitors up to five supply rails simultaneously, with five adjustable threshold voltages configurable via external resistor dividers. It asserts a common active-low reset output (push-pull, totem pole) when any monitored voltage falls below its threshold, with a minimum reset timeout of 1 ms to ensure the downstream processor or logic sees a clean restart pulse.
What the five adjustable thresholds mean for your BOM
Five independent voltage monitors in one package let a single MAX8214AEPE supervise the core, I/O, memory, PLL, and auxiliary rails of a multi-rail system — reducing component count versus five single-channel supervisors. Each threshold is set by an external resistor divider tied to the corresponding sense input, giving you per-rail trip points that are not fixed at the factory. This flexibility is useful when the same PCB must support multiple processor variants with different supply tolerances.
