Power management integrated circuits (PMIC) are a type of integrated circuit that perform numerous power management functions. One of the more popular types of PMICs are supervisors, which are designed to detect various power management conditions and issue an appropriate alert. PMIC - Supervisors, such as LTC2935IDC-2, are designed to monitor various conditions like voltage, temperature and current, and provide fault indication of the conditions. In this article we will be discussing the application field and working principle of the LTC2935IDC-2 Supervisor IC.

The LTC2935IDC-2 Supervisor IC is a single channel power/temperature supervisor that features a programmable threshold. It has an ultra-low quiescent current of 2 µA and is suitable for use in applications that require low power consumption and minimal component count. The LTC2935IDC-2 Supervisor IC can be used in a number of different applications, including computers, automotive, industrial, medical, and consumer applications. It can be used to monitor power supplies synchronize power supply sequencing, provide power-up and power-down sequencing security, monitor processor brownout on-off switch control, monitor system signals for abnormality, monitor temperature and provide warning for temperature faults, monitor input voltage, monitor fan speed, and monitor battery charge status.Because it is a single channel power/temperature supervisor, it is designed to monitor temperature parameters in addition to power-related parameters. The programmable temperature threshold allows the supervisor to detect when the temperature is out of range and issue an appropriate warning. In addition to temperature, the IC can be used to monitor voltage, current, and various power sequence events.The working principle of the LTC2935IDC-2 Supervisor IC is simple. It contains a Comparator that compares the monitored power or temperature parameters against a pre-programmed threshold. When the parameters reach above or below that threshold, the comparator will output an Alert signal to an external power management IC (PMIC) or a monitoring device. This alert signal indicates that the monitored parameters have exceeded the pre-programmed thresholds, and should prompt the user to take action accordingly.The LTC2935IDC-2 Supervisor IC is an ideal device for applications that require low power consumption, minimal component count, and accurate monitoring of power/temperature parameters. Its wide range of applications, along with its fast response time and programmable thresholds, make it an ideal choice for many different power management applications.
