Reset remains asserted for a minimum of 140 ms after all monitored voltages return above threshold, giving the system power-on-reset hold time without external timing components. ## Reset output and timing for the BOM The push-pull, totem-pole output drives the reset line directly without a pull-up resistor — the output stays low during the fault and releases high when the supply is valid and the timeout expires. Housed in a 5-pin SOT-23 (SC-74A), the part occupies minimal board area and shares the same footprint as many single-voltage supervisors — a layout that already routes two sense inputs can reuse the same land pattern.","metaTitle":"MAX6309UK29D3+T Multi-Voltage Supervisor, 2.93V Threshold","metaDescription":"Analog Devices MAX6309UK29D3+T multi-voltage supervisor, 2 channels, active-low reset, 140ms timeout, SOT-23-5.
