MAX690AESA

MAX690A/MAX692A/MAX802L/MAX802M/MAX805L reduce the complication and quantity of materials necessary for power-supply monitoring and battery-control operations. When compared to separate ICs or discrete components, they significantly increase system dependability and precision. These components provide four purposes: 1) During power-up, power-down, and brownout scenarios, a reset output is provided. 2) Battery-backed logic switching for CMOS RAM, CMOSP, and other low-power logic. 3) If the optional watchdog timer has not been toggled within 1.6 seconds, a reset pulse is sent. 4) A 1.25V threshold sensor for power-failure detection, low-battery detection, or monitoring a power supply other than 5V. The reset-voltage threshold levels and reset outputs of the parts differ. When the supply voltage dips below 4.65V, the MAX690A/MAX802L/MAX805L generate a reset pulse, while the MAX692A/MAX802M produce a reset pulse once the supply voltage goes below 4.40V.
