Power management integrated circuit (PMIC) are one of the most important chips used in most modern electronic systems. PMICs are used to regulate the supply and consumption of electrical power in a system. Amongst all types of PMICs, one type stands out; Supervisors. Supervisors help to prevent over-current, under-voltage and over-voltage conditions by monitoring and providing a reset condition when needed. ISL88003IH22Z-TK is an example application and working principle of a PMIC Supervisor.

The ISL88003IH22Z-TK is a precision 3.3V/5V microprocessor supervisor with internal RAM, reset/watchdog timer, and a system power-on reset generator. It provides precise detection of overvoltage, undervoltage and over-temperature, and is designed to protect a variety of digital systems. The device is optimized for precise detection by using an internal 12-bit analog-to-digital converter.

The features of the ISL88003IH22Z-TK include an active-low manual reset, active-low reset with an adjustable timeout, active-low reset for a single fault, and an active-low reset for dual fault conditions. Additionally, the device incorporates a number of diagnostic features such as a power-on reset status LED, an active-low manual reset LED, and a programmable active-low reset delay. With this feature, designers can easily adjust the reset and notify times to meet the application requirements.

The ISL88003IH22Z-TK is ideally suited for applications requiring precise reset and detection of overvoltage, undervoltage, and over-temperature conditions. It is designed to easily integrate into a variety of power systems, such as laptops, desktop computers, storage systems and embedded systems. Additionally, the ISL88003IH22Z-TK supports wide temperature range operation, allowing it to be used in extreme environment applications as well.

The ISL88003IH22Z-TK has an efficient working principle. When a fault condition is detected, the device activates an active-low reset signal that is externally connected to a microprocessor. This active-low reset signal is routed to the reset terminals of the device and the microcontroller, the microcontroller then goes into a reset state, the fault condition is then debounced so no false signals are generated. When the fault is cleared, the device releases the active-low reset signal and the microcontroller will restart.

In summary, the ISL88003IH22Z-TK is an example application and working principle of a PMIC supervisor. It provides precise detection of overvoltage, undervoltage and over-temperature conditions, and is designed to protect a variety of digital systems. The device also offers a wide temperature range, a number of diagnostic features, and a precise reset and detection operation. With its efficient reset and detection operation, the ISL88003IH22Z-TK is an ideal chip for a variety of applications that require precision power management.
