Description
The MAX699CPA IC is a versatile and cost-effective solution for power-on reset and watchdog timer control in electronic systems. It ensures reliable startup by monitoring the power supply and provides a watchdog timer to prevent system lock-up. With its low-cost design, it's an ideal choice for budget-conscious projects seeking dependable reset and watchdog functionality.
Monitors the +5V supply in microprocessor (μP) and digital systems. They supply a RESET pulse of at least 140ms duration on power-up, power-down, and during low-voltage brownout conditions. Circuit reliability is increased at a reduced cost by eliminating all external components and adjustments.
The MAX699 includes all the features of the MAX698 but also provides a watchdog input to monitor microprocessor activity. The RESET output goes low if the watchdog input (WDI) is not toggled within 1 second. The watchdog feature can be disabled by leaving WDI open.
