Power management integrated circuits (PMICs) are integrated circuits designed to provide efficient power management solutions for modern electronic devices. PMICs are critical components that enable the power efficiency and thermal stability of devices. They influence the overall operating performance and reliability of modern electronic devices. Supervisors are a class of PMICs that provide protective power supply control for electronic devices. The LTC2900-1CDD#TRPBF is a supervisor IC (integrated circuit) for implementing device-level power supply sequencing and system-level power sequencing. This article will provide an overview of the application field and working principle of the supervisory IC.

The LTC2900-1CDD#TRPBF is a dual-channel supervisor IC specifically designed to provide precision power sequencing and generator control in a variety of applications. It is designed to provide low-voltage protection, system reset, and voltage sequencing in applications where the control power supply needs to be monitored. The device features integrated precision voltage reference, compared against the monitored voltage, in order to detect when the power is lost. With the help of an OR gate, the device provides two independent generators for system reset and for soft-start. The device operates from a nominal 2.7V to 5.5V supply.

The LTC2900-1CDD#TRPBF is designed to monitor either two power supplies or one power supply with a battery backup. The device can detect five thresholds; voltage loss, voltage gain, battery backup, overvoltage, and undervoltage. The hysteresis of each threshold can be programmed by connecting external resistors to the power supply. The device features two independent open drain outputs. The output voltage level can be configured down to 1.2V. The open drain outputs can be used to drive an LED or FET in order to provide a visual indication of the power situation. The device has a programmable timeout period to prevent a false reset when an intermittent power failure occurs.

The primary application of the LTC2900-1CDD#TRPBF is as a power supervisor for electronic devices. The device can be used to provide device-level power supply sequencing and system-level power sequencing. The device can be used in security systems, medical and portable imaging systems, hard disk drives, automotive applications, and other applications that require advanced power management. The device can also be used as a system reset timer or a power fail detector for embedded systems or automotive safety systems.
