PMIC - Supervisors

A supervisor, in the context of power management integrated circuits (PMICs), is a form of integrated circuit (IC) designed to monitor the power system of a device and send a designated signal to other components in the circuit when its levels exceed certain pre-defined thresholds. It is usually part of a complex system, where other components provide control, conversion, and other functions, and work together to serve a specific purpose. It is typically used in devices that use a battery power source, such as wireless devices, TVs, computers and laptops, tablets, hand-held devices, and wearable electronics.

The S-1000N17-M5T1U supervisor is a highly configurable standard PMIC supervisor that provides an ideal solution for a wide range of applications. It has an extensive range of features, including an adjustable threshold detect (ATD) monitor, an external reset input, a delay time range of up to 10 seconds, adjustable open-drain output drive capability, active-low reset output, and an active-high external reset input.

Application Field

The S-1000N17-M5T1U can be used in a variety of applications, including portable electronic systems, mobile phones, wearables, smart home appliances, point-of-sale systems, tablets, and automotive applications. It provides an efficient and accurate power system monitoring solution for applications where fast short-term overvoltage/overcurrent protection and/or fast open-drain reset is required.

Working Principle

The S-1000N17-M5T1U supervisor can detect three key power system conditions: overvoltage, undervoltage, and overcurrent. When the thresholds for these conditions are exceeded, the IC can take action. For example, when an overvoltage condition is detected it can send out a reset signal. In the case of an undervoltage condition, the device can immediately shut off power to the load, thusavoiding further damage.

The S-1000N17-M5T1U can be programmed to detect a wide range of voltages and currents, thus providing a robust and reliable power management solution. It also has an ATD monitor, which is used to detect any sudden increase in supply voltage or current that exceeds the nominal operating limits. The ATD monitor can then immediately activate the reset function, which will send out an active-low reset signal.

In addition to its ATD monitor, the S-1000N17-M5T1U features adjustable open-drain output drive current, allowing it to be used in applications where a very low standby power consumption is required. The IC is also capable of driving up to 16 loads in parallel, making it a suitable option for use in applications with multiple power sources.

The S-1000N17-M5T1U is a highly advanced and configurable supervisor and is an ideal choice for power system monitoring and protection in a wide range of applications.
