One channel has a fixed 2.19 V threshold; the second is adjustable via an external resistor divider, so the same part covers a 3.3 V main rail and a 1.8 V or 1.2 V core rail with one resistor. ## Reset timing and temperature range Reset timeout is a minimum of 140 ms — long enough to let the downstream rails stabilise after a brown-out or power-up, but short enough that a 200 ms power-cycle resets the system cleanly.","metaTitle":"MAX6387XS22D3+ Power Supply Monitor, 2.19V Threshold","metaDescription":"MAX6387XS22D3+ Power Supply Monitor from Analog Devices.
