PMIC - Supervisors are a set of components that can be used to monitor an active power supply system. In particular, they are used to measure voltage, current and temperature in order to detect any irregularities in the system. One of the leading PMIC supervisors on the market is the LTC2960HDC-1 from Linear Technology. In this article, we will explore the application fields and working principles behind this popular product.

LTC2960HDC-1 Overview

The LTC2960HDC-1 is a dual-channel, low-voltage, low-power PMIC supervisor. It is designed for use in applications ranging from portable notebook computers, tablets, and handhelds to industrial instruments, medical equipment, and wearable technology. The device has two independent voltage monitoring inputs that allow it to monitor two separate power rails or a single rail with two independent voltage thresholds. Additionally, the device offers constant-current current-sense inputs that can be used to detect over-current conditions.

The LTC2960HDC-1 also offers a temperature-sense input that allows the supervisor to detect a temperature rise above the set-point. This feature is especially useful for thermal management applications. Additionally, the device features a power-saving sequencing pin that allows the device to enter low-power mode when the monitored voltage is below a certain set point.

Application Fields

The LTC2960HDC-1 is designed to meet the needs of portable applications, where power is constrained and power supply integrity is a critical issue. Once connected to the system, the device monitors both the voltage and current of the power supply. If an over-voltage, under-voltage, or over-current condition is detected, the supervisor will send out a signal to signal that something is wrong and the power supply should be disconnected.

The device also has a feature called “filter output” which can be used to ignore short-term spikes or transients on the power supply. This feature is helpful for applications such as automotive, where the power supply can experience large, short-duration transients that would otherwise cause the supervisor to trip.

The device also features a built-in power sequencing pin that can be used to delay the connection of the power supply until all the required power rails are connected. This feature is useful for applications where multiple power sources need to be connected in a specific order.

Working Principle

The LTC2960HDC-1 uses a combination of voltage and current monitoring to detect and protect against over-voltage, under-voltage, and over-current conditions. The device has two separate inputs for voltage monitoring, which can be used to monitor two different power rails or a single power rail with two independent voltage thresholds. For over-voltage or under-voltage protection, the device compares the input voltage to its predetermined thresholds. If the input voltage exceeds either threshold, the device signals an alert and can shut down the power supply.

For over-current protection, the device uses its constant-current current-sense inputs to detect when the current falls above a predetermined threshold. If an over-current condition is detected, the device will send out a signal to shut down the power supply.

The device also has a temperature-sense input, which can be used to detect a temperature rise above the set-point. The LTC2960HDC-1 can be used to manager the temperature in a system and shut down the power supply when the temperature rises to dangerous levels.

Conclusion

The LTC2960HDC-1 is an excellent PMIC supervisor designed for portable, low-power applications. It is designed to provide over-voltage, under-voltage, and over-current protection, as well as temperature monitoring. The device has a wide range of application fields and can be used to protect and manage power supplies in computers, medical equipment, automotive, and a range of other industrial and consumer applications.
