The Maxim Integrated MAX6735KATGD3+ is a triple-voltage microprocessor supervisor in a SOT-23-8 package. It monitors three supply rails — 1.11 V, 3.075 V, and one adjustable threshold — and asserts an active-low reset when any monitored voltage falls below its threshold. The reset output is push-pull, totem-pole, so no external pull-up resistor is needed on the reset line. With a minimum reset timeout of 140 ms, it holds the system in reset long enough for all rails to stabilise before the processor starts.
The three monitored thresholds cover 1.11 V, 3.075 V, and an adjustable input. The 140 ms minimum reset timeout ensures the processor sees a clean power-good signal after all supplies have ramped, even in systems with slow-start converters or large bulk capacitance.
Automotive qualification and lifecycle
This qualification also makes it a strong candidate for industrial applications where long-term reliability is critical.
