Introduction

Power Management Integrated Circuit (PMIC) supervisory products are one type of device designed to serve a variety of purposes for the power management of a wide range of electronic devices. In this article, we look at the application field and working principle of the CAT1023WI-25-GT3 Supervision Circuit from On Semiconductor.

Overview of CAT1023WI-25-GT3 Supervisory Circuit

The CAT1023WI-25-GT3 is a low-voltage, high-accuracy voltage supervisor circuit with an adjustable threshold voltage range of 0.9 to 3.85 volts. It is capable of detecting, monitoring, and regulating low-voltage outputs. The device is implemented with a low-voltage, low-current requirement, making it ideal for use in applications where minimal space and power consumption are important.

Application and Features of CAT1023WI-25-GT3

This device is suitable for many applications such as embedded control, power management space-constrained designs and low-voltage distributed power management architectures. The features of the device include:

• Wide supply voltage range from 2.7 to 5.5V
• Multiple voltage threshold levels from 0.9 to 3.85V
• Low typical supply current of 4μA
• Integrated window comparator
• Integrated voltage reference
• Close- and open-drain outputs available
• High Accuracy 10mV voltage threshold

Working Principle

The CAT1023WI-25-GT3 device is designed to detect, monitor, and regulate low-voltage outputs. The device contains an integrated voltage reference, a comparator with an adjustable voltage threshold and two outputs: an active low RESET output and an active high WARN output. The external configuration of the device consists of an external resistor and capacitor. When the external input voltage is at or above the programmed voltage threshold, the RESET and WARN outputs are held low. When the voltage is below the programmed threshold, the RESET output is asserted low, while the WARN output is asserted high. This allows the user to set the device to trigger an external event when the voltage falls below a certain point. If the input voltage falls below the threshold level, the RESET will be asserted low until the voltage goes above the voltage threshold again. The RESET and WARN outputs are latched in their current states until the input voltage rises above the reset threshold, at which point they will both be reset to their default state. The input voltage rising above the voltage threshold in the wake of a power-on-reset event or a manual reset will be considered as the new reference voltage by the device. The voltage threshold voltage is adjustable from 0.9V to 3.85V using external resistors.

Conclusion

The CAT1023WI-25-GT3 Supervisory Circuit from On Semiconductor combines a low-voltage, high-accuracy voltage supervisor circuit with an adjustable threshold voltage range of 0.9 to 3.85 volts. It is suitable for a variety of application such as embedded control and low-voltage distributed power management architectures. Moreover, the device includes integrated voltage reference, a comparator, and two outputs. This makes it ideal for applications where power consumption is a concern. The device also offers adjustable voltage threshold and close- and open-drain outputs. In short, the CAT1023WI-25-GT3 is an ideal solution for low-voltage power management applications in a variety of industries.
