Power management integrated circuits (PMICs) are a type of semiconductor integrated circuits (ICs)that provide complex power control circuitry for powering electronic applications. PMICs are used in a variety of applications, ranging from portable electronic products such as cell phones and laptops to systems like automobiles, industrial controllers, and telecom infrastructure. PMICs allow for complex integrations of multiple voltage levels required to power components like CPUs, memories, and wireless communication modules. This can eliminate the need for having multiple standalone power supplies as well as improve system efficiency.

Supervisors in PMICs are a set of functions which are used to monitor the operating conditions of the system and to provide corrective actions when required. The most common supervisors are power-on reset, watchdog timer, brownout detectors, and overvoltage protection. These functions are used to ensure the system is operating within the desired parameters of power-up, power-down, and in-between conditions.

The S-80915CNPF-G8KTFU is an ultra-low power supervisor PMIC chip which is designed to manage system power up and reset in handheld devices such as cell phones, tablets, and other embedded systems. It can also be used in automotive applications. It features low power consumption, a 2.9V to 5.5V VDD supply range and a wide -40C to 85C temperature range.

The S-80915CNPF-G8KTFU offers a 3-in-1 function of power on reset, watchdog timer and voltage supervisor. The reset circuit monitors two power inputs (VCC1 and VCC2) and generates a reset signal in case of an unexpected power glitch or operational failure. The watchdog timer (WDT) keeps track of key system functions to ensure the system is not stuck in misbehaving states. The voltage supervisor (LVP) provides a signal when the system voltage levels go below the pre-defined threshold levels.

The S-80915CNPF-G8KTFU has a number of features that make it an attractive choice for many applications, such as:

• Ultra-low power consumption, especially at open-drain reset outputs
• A Pre-defined Reset Debounce Time of 10ms
• A Pre-defined WDT Time-out of 16s, adjustable up to 64s duration
• Automatic power-on reset (POR) and power-down reset (PDR) features
• Programmable reset and watchdog timer output levels
• Overvoltage protection of up to 6.2V

The S-80915CNPF-G8KTFU is ideal for a variety of applications such as mobile phones, tablet PCs, and automotive systems. It provides a simple and reliable way of monitoring the system’s power and reset levels, helping to ensure that the system is running as expected and that system reliability is maintained.
