PMIC or Power Management Integrated Circuits are integral part of all electronic and electric designs. In order to control the power distribution, varying power levels to digital, analog and all other peripherals, these devices come in handy. PMICs are used in digital and analog circuits alike, primarily due to their ability to regulate and accurately manage power levels.

The CAT1162WI-42-GT3 is a PMIC – Supervisors from On Semiconductors. It is a high performance microcontroller supervisory and power management circuit that offers versatile and easy power supply design. It provides reliable poly-phase regulation and fault protection for PC and microcontroller based devices.

The CAT1162WI-42-GT3 is designed to detect fault conditions and alert the system to allow necessary corrective action. It provides complete protection against various power supply and system faults and reduces the need for complicated external circuits to achieve system stability and reliability.

The platform features multi-levle power control, a wide input voltage range, an adjustable fixed caution/fault threshold and a dedicated power-on reset (POR) source. It has high-performance configurable regulators with an adjustable output voltage range between 0.8V and 5.0V. Additionally, the device integrates fault protection, power management and controller supervisory functions.

With regards to its application field, the CAT1162WI-42-GT3 is well suited for a variety of applications including computers, digital audio systems and consumer electronics. It provides low quiescent current for extended battery operation and is flexible enough to handle a range of input supply voltages. This makes it an ideal choice for domestic, automotive and industrial applications.

Now let’s take a look at how the CAT1162WI-42-GT3 operates. It consists of 4 main blocks—reset circuit, voltage supervisor, power monitor and power up detector. The reset circuit is responsible for controlling the initial power-up sequence of complex microcontrollers. It features three programmable reset outputs that generate power-on reset and system reset signals, which help ensure orderly system reset in multiple firmware environments.

The integrated voltage supervisor manages the power supply voltages of all the peripherals, providing voltage monitoring and monitoring configuration. It features a programmable caution, warning and fault thresholds, which allow a wide range of adjustments and can detect over-voltage, under-voltage and brownout conditions.

The power monitor monitors current consumption and reports dangerous power conditions. It can accurately monitor input supply current, microcontroller core voltage and peripheral consumption currents, providing diagnostic and warning signals to the system in case of critical power supply and load conditions.

Finally, the power up detector starts the power-up sequence of the system when the power supply reaches the desired value. It includes an adjustable delay for the detection of power supply transients, an enable pin for secure initialization and an enable enable flag for secure initialization.

To conclude, the CAT1162WI-42-GT3 PMIC – Supervisor provides a low-risk and optimized design solution for voltage monitoring, power control and system fault protection. With its versatile and easy power supply design, high-performance configurable regulators and reliable poly-phase regulation, the CAT1162WI-42-GT3 is ideal for applications requiring reliable power supply and system management.
