A PMIC - Supervisors is a power management integrated circuit (IC) used to control and monitor the power status of electronic devices. The N84C163WD25TG is one such supervisor IC and has been designed for use in microprocessor and peripheral applications. This IC is suitable for use in microprocessors, DSPs, programmable logic controllers, automotive microcontrollers, displays and other similar devices.

The N84C163WD25TG supervisor IC consists of one selectable reset output, one watchdog timer output, and three selectable voltage threshold monitor circuits. The reset output circuit provides a reset pulse when the monitored voltage levels exceed either the over or undershoot thresholds. The watchdog timer output circuit monitors a signal source and if necessary, produces a reset pulse when the input signal fails or a timeout occurs. The three selectable voltage threshold monitor circuits can provide two open-drain outputs and one active-low reset output. They can be used to monitor several critical voltage levels within a microprocessor.

The N84C163WD25TG supervisor IC is available in both 8-pin and 20-pin packages and has an input voltage range from 1.6V to 5.5V. It has a very low power consumption, is well suited for single-supply and split-supply systems, and has a temperature range from -40°C to 125°C. The operating temperature range, along with its robust design, makes it well suited for use in applications that require extreme temperature ranges, such as automotive and industrial applications.

The operation of the N84C163WD25TG supervisor IC is based on a premise that it will detect an error condition upon application of power to the device, and then reset the microprocessor or other associated device. To do this, the supervisor IC monitors the voltage level of any of the monitored circuit blocks. If the voltage level drops below the over or undershoot threshold, it produces a reset pulse, which will cause the microprocessor or associated device to be reset and the error condition is reset. The watchdog timer output circuit, on the other hand, will produce a reset pulse if a monitored signal fails or a timeout occurs.

The N84C163WD25TG supervisor IC is well suited for use in many types of applications, such as microprocessors, DSP, programmable logic controllers, automotive microcontrollers, displays, and many others. It has a wide temperature range and delivers excellent reliability and performance in even the toughest industrial environments. Further, it has a very low power consumption, which makes it ideal for battery-powered devices. Additionally, its robust design ensures it will last for many years.
