MAX6313UK35D1-T is a supervisory-management integrated circuit (PMIC - Supervisors), which combines a watchdog timer, reset detector, and a power-fail comparator into one unit with a very small footprint. PMIC - Supervisors are used in a wide variety of applications such as industrial, computer, and consumer applications.

The MAX6313UK35D1-T enables system designers to utilize a single integrated circuit that offers features found in multiple discrete ICs. It features a highly integrated watchdog timer, reset controller, and power-fail monitoring system that is designed to ensure that systems remain within safe operating parameters.

The watchdog timer is typically used on microprocessors to ensure that processor failure or freeze-up cannot hang the system. The MAX6313UK35D1-T watchdog timer will continuously monitor the system status by observing an external time (WDT) signal from the processor or other system devices, via an active-low input pin. If the WDT signal is not serviced within the programmed watchdog timeout period (from 30 ms to 2.4 s), the watchdog timer will produce an externally visible reset signal (RESET) at its output pin to reset the system.

The reset detector is used to detect power faults and reset the system. It contains an input pin that is actively compared with the generated internal reset signal (VCCR). When the VCCR voltage level becomes greater than the voltage at the RES pin, the detector will issue a reset signal (RESET). This reset signal is used to reset the system after a power fault is detected.

The power-fail comparator is used to generate a power-fail signal during power fault conditions. The MAX6313UK35D1-T uses a +1.24V reference voltage, calibrated to within ±50mV of the specified power-fail voltage level. When the voltage on the VDD pin is below the specified level, the P-FAIL output is pulled low. This power-fail signal can be used to switch the system off in order to prevent possible damage.

The MAX6313UK35D1-T is available in an 8-pin micro-XDFN package, with a maximum operating temperature range of -40°C to +85°C. It has an operating voltage range of 2.0V to 5.5V and can consume up to 45µA of supply current. It is also available in a variety of different packages, including SOIC, MSOP, and TDFN.

The MAX6313UK35D1-T has a host of features and is well suited for many different applications, including embedded, industrial, computer, and consumer applications. It is also an ideal solution for systems that require power-fail protection, watchdog reset, and reset detection. Its small size, low power consumption, and high integration make it an attractive choice for any system designer.
