Additional Details

The MAX6412–MAX6420 low-power microprocessor supervisor circuits monitor system voltages from 1.6V to 5V. These devices are designed to assert a reset signal whenever the V_CC supply voltage or RESET IN falls below its reset threshold or the manual reset input is asserted. The reset output remains asserted for the reset timeout period after V_CC and RESET IN rise above the reset threshold and the manual reset input is deasserted. The reset timeout is externally set by a capacitor to provide more flexibility.

The MAX6412/MAX6413/MAX6414 feature fixed thresholds from 1.575V to 5V in approximately 100mV increments and a manual reset input. The MAX6415/MAX6416/MAX6417 are offered with an adjustable reset input that can monitor voltages down to 1.26V and the MAX6418/MAX6419/MAX6420 are offered with one fixed input and one adjustable input to monitor dual-voltage systems.

The MAX6412/MAX6415/MAX6418 have an active-low, push-pull reset output. The MAX6413/MAX6416/MAX6419 have an active-high, push-pull reset output and the MAX6414/MAX6417/MAX6420 have an active-low, open-drain reset output. All of these devices are offered in a SOT23-5 package and are fully specified from -40°C to +125°C.
