ADM6713LAKSZ-REEL

PMIC - Supervisors are power management integrated circuits that are designed to monitor voltages on a system and provide quick, reliable protection against unexpected faults or overvoltage conditions, ensuring system safety and power integrity. A common type of supervisor IC is the ADM6713LAKSZ-REEL. In this article, we will look at the ADM6713LAKSZ-REEL\'s application field and working principle.

Application Field

The ADM6713LAKSZ-REEL is a low-cost, high-performance supervisor IC and is specifically designed to monitor and supervise three independent and adjustable output voltages: 3.3V, 1.5V and 1.8V. It measures the voltage in each output and sends a low logic reset to any output that falls below the predetermined voltage. It also features a watchdog input, enabling a system-level controller to reset the system if needed. This supervisor IC is ideal for applications that require an efficient and reliable voltage monitoring solution, such as notebook computers, digital cameras and portable devices.

Working Principle

The ADM6713LAKSZ-REEL employs a low-cost two-wire serial interface for read/write operations, which can be used to program the voltage levels at which a reset is generated. It contains internal latches to guard against short-term supply transients and other disturbances. The supervisor includes an input voltage monitor, an independent reset output, an independent watchdog timer output, and a programmable reset delay. The reset output can be set to trigger either when an overvoltage or undervoltage condition is detected, or when the watchdog timer is expired. When an overvoltage or undervoltage is detected, the reset output is pulled low and immediately triggers the reset. The reset delay time is adjustable, and it can either hold the reset low until an appropriate voltage is applied or reset the system when the supply voltage returns to normal. With its high-performance, low-cost design, the ADM6713LAKSZ-REEL is an ideal choice for a variety of power management applications.

Conclusion

The ADM6713LAKSZ-REEL is a low-cost, high-performance supervisor IC that is designed to monitor and ensure the safety and power integrity of electronic systems. It offers an adjustable, two-wire serial interface for read/write operations, an input voltage monitor, independent reset and watchdog outputs, and adjustable reset delay. With its reliable, efficient design, the ADM6713LAKSZ-REEL is a great choice for a variety of power management applications.
