PMIC - Supervisors are semiconductor products used to maintain proper operation of the power system on a variety of different devices, ranging from mobile phones to industrial equipment. The LTC2911HDDB-1 Supervisory product is a key component in the power management system, providing reliable and accurate monitoring and protection of the system. It is an easy-to-use, intuitive and powerful device that offers multiple options to serve its purpose effectively.
Overview
The LTC2911HDDB-1 is a PMIC - Supervisory device designed for consumer, industrial, and automotive applications. The device offers superior transformer-less over/under voltage/current protection, and it uses buffered outputs to provide robust outputs that drive up to 10 FETs. The LTC2911HDDB-1 features full-featured over-temperature protection and accurate over-voltage/over-current protection, as well as an integrated digital temperature sensor. The device also offers a wide input voltage range from 5.5V to 28V and a regulated output voltage range of 3.3V to 5V. The LTC2911HDDB-1 is designed to provide accuracy and flexibility in power management, allowing for a range of applications.Application Fields
The LTC2911HDDB-1 is suitable for a range of applications in consumer, industrial, and automotive industries, including:- Protection of sensitive electronics in industrial applications
- Over/under voltage protection in automotive applications
- Battery monitoring and protection in consumer electronics
- Supply regulation in motor driver circuits
- System reset and supervisor functions
Working Principle
The LTC2911HDDB-1 uses a comparison based algorithm for tracking the input voltage. The device compares the input voltage to two preset thresholds (OTP and UVP), generating the corresponding outputs, depending on the monitored voltage. When the input voltage is between the two thresholds, the device will output a low level at all pins. When the monitored voltage is above the OTP threshold (over-temperature protection), the device will generate a logic-level high output at all pins, driving the FETs, indicating that the device is in an over-temperature alert state. Similarly, when the input voltage is below the UVP threshold (under-voltage protection), the device will activate the FETs, indicating that the device is in an under-voltage alert state. This will result in an appropriate response, such as a system reset, in order to protect the system from potential damage. The device also features integrated Digital and Analog Temperature Sensors, which can be used to monitor the device’s operating temperature, as well as providing a temperature warning signal.Conclusion
The LTC2911HDDB-1 is a reliable PMIC - Supervisory device, designed to provide efficient and cost-effective over/under voltage protection for a wide range of applications. The device features superior over/under voltage protection, as well as integrated temperature sensors, making it an ideal solution for maintaining system stability. Its simple, intuitive design and wide-ranging capabilities make it suitable for a variety of applications in consumer, industrial, and automotive industries.The specific data is subject to PDF, and the above content is for reference
