The MAX824LEXK+T is a precision, low power, zero-delay, push-pull supervisor IC that provides safeguards against system errors and prevents CPU lockup. It is ideal for use in automotive systems, handheld electronics, and medical devices. The device features a low power (1µA) standby mode, and has thermal and voltage monitoring functions, which are especially important in automotive applications. A watchdog timer (WDT) can be enabled or disabled via a dedicated DAC pin. In addition, the MAX824LEXK+T includes a noise filter, voltage reset and glitch protection, integrated reset delay, and an adjustable reset timeout option. All these features, combined with a robust design, make the MAX824LEXK+T a reliable solution for protecting systems against reset failures and power supply interruptions.

The MAX824LEXK+T is based on a current limited CMOS architecture, designed to provide maximum power efficiency and low power consumption. This power-saving feature makes it an ideal solution for battery-powered and energy-sensitive devices. The device has two externally adjustable reset timeout options, providing flexibility to adjust reset timeout to custom application requirements. The user can configure the reset timeout range from 30 ms to 8.3 sec (8.3 to 13.3 sec with temperature compensation). The MAX824LEXK+T also features an integrated noise filter and glitch protection, improving system reliability and reducing power consumption.

The MAX824LEXK+T is powered from an external 5V supply and has an operating temperature range of -40 to +85° C. The device includes a watchdog timer with an adjustable timeout period and a selectable reset pulse width. The watchdog timer can be enabled or disabled via an external DAC pin. The device also has a thermal monitoring input that allows it to detect temperature changes and take appropriate action if needed.

The MAX824LEXK+T is typically used to guard against system faults, unexpected lockups, brownouts, power surges, and transients. It is a great solution for automotive applications since its thermal monitoring feature can detect sudden changes in temperature, and then reset the system before damage occurs. Additionally, the MAX824LEXK+T\'s adjustable reset timeout can be used to meet special needs associated with a system\'s design requirements. The device\'s robust voltage monitoring features help protect systems against reset failures, brownouts, and power supply interruptions. In conclusion, the MAX824LEXK+T is an excellent device for protecting systems from unexpected and potentially damaging situations.
