Three-voltage monitoring in a compact SOT-23-8
The MAX6735KASHD3 is a multi-voltage supervisor from Analog Devices that monitors three independent supply rails simultaneously, asserting a common active-low reset output when any monitored voltage falls below its threshold. Thresholds are set at 1.313 V, 2.925 V, and a third adjustable input, covering common core and I/O supply levels in mixed-voltage designs.
Reset timing and temperature range
A minimum reset timeout of 140 ms holds the reset line low after all monitored voltages return above threshold, giving the system power supplies and clock oscillators time to stabilise before the processor starts executing code.
Active lifecycle and sourcing
It is listed as RoHS non-compliant, so verify local regulatory requirements before specifying for new designs.
