Power management integrated circuits (PMICs) perform a variety of critical functions in modern electronic systems, from regulating power supply voltages to monitoring system states. These devices are available in a variety of form factors, from complex multi-function integrated circuits (ICs) to small, single-function components. The ISL60002CIH326Z-TK is a voltage reference PMIC device that is designed for use in automotive and industrial applications. This device provides a precision reference voltage that can be used to set or regulate the output voltage of power supplies.

Device Features and Specifications

The ISL60002CIH326Z-TK is a highly versatile PMIC. It is an ultra-low power voltage reference device with a temperature compensation circuit that allows operation over a wide temperature range. The device features a wide input voltage range of 2.7V to 17V and an output voltage range of 0.8V to 13V. It is also capable of providing a stable output voltage over a wide operating temperature range of -40°C to 150°C.

The device also has an integrated auto-discharge circuit that will quickly discharge the output voltage when the input voltage is removed. This prevents the output voltage from rising above the specified voltage level during power-off periods. The device also has an integrated under-voltage lockout circuit that prevents the output voltage from dropping below a predetermined level.

Other features include reverse current protection, a thermal protection circuit that shuts down the output voltage when the operating temperature exceeds an internal threshold, and an over-voltage protection circuit that will shut down the output voltage if it exceeds the specified level. The device also has an adjustable pull-down resistor that can be used to set the output voltage level.

Working Principle

The ISL60002CIH326Z-TK works by applying a voltage reference to the output voltage. The voltage reference is generated internally by an accurate temperature-compensated voltage reference circuit. This circuit uses the temperature-compensation circuit to compensate for changes in temperature and ensure that the output voltage remains stable over the wide operating temperature range.

The output voltage level is set by adjusting the pull-down resistor. This adjusts the threshold voltage that the output voltage must surpass in order to turn “on”. The output voltage level is then manually adjusted until it achieves the desired value. Once set, the output voltage will remain at the desired level over the full range of operating temperatures as long as the input voltage is kept within the specified limits.

Applications

The ISL60002CIH326Z-TK is a highly versatile and accurate voltage reference device. It is designed for use in automotive and industrial applications, where stable and highly accurate voltage levels are required. It can be used to set or regulate the output voltage of power supplies and ensure that the output voltage remains at the desired level over the full range of operating temperatures.

The device is also suitable for use in medical, transportation, and communication applications, where high precision and accuracy are required. Additionally, it can be used in safety-critical applications where the output voltage must remain within safe limits at all times.

Conclusion

The ISL60002CIH326Z-TK is a highly accurate and reliable voltage reference PMIC device. It features an ultra-low power design and a wide input and output voltage range, with adjustable pull-down resistor for setting the output voltage level. It provides a stable output voltage over a wide temperature range, and has integrated protection circuits that prevent the output voltage from exceeding specified limits. This makes it suitable for a variety of automotive, industrial, medical, transportation, and communication applications.
