125nA microprocessor supervisory device for power-sensitive applications
Maxim has introduced the MAX16056-MAX16059, a 125nA microprocessor supervisory circuits that monitor a single system supply voltage, features capacitor-adjustable watchdog and reset timeouts to enable unique power-saving schemes, and these devices are suitable for battery-powered devices, handheld electronics, metering equipment, and other applications where battery life is crucial.
The MAX16056-MAX16059 are used to wake up the processor periodically, and then turn off the processor when the required functions are completed. And also be used as low-power oscillators to conserve energy, as they consume less power than integrated adjustable oscillators.
The MAX16056-MAX16059 monitor voltages from 1.575V to 4.625V, and assert a reset signal whenever the VCC supply voltage drops below the reset threshold, manual reset is pulled low, or the watchdog timer (MAX16056/MAX16058) runs out. The reset function features immunity to power-supply transients.
The MAX16056-MAX16059 operating input voltage ranging from 1.1V to 5.5V, and are available in push-pull or open-drain output configurations. A manual-reset input facilitates testing.
Operating temperature range: -40°C to +125°C
