TPS3707-30D

Power management integrated circuits (PMIC) are a vital component for enabling efficient power management for a multitude of applications, including portable and embedded computing, medical technology, industrial and automotive. The TPS3707-30D is a supervisor IC that enables users to implement power management for the full range of applications that rely on high performance and low power. The TPS3707-30D provides superior power mangement capabilities that ensure that the device is protected from potential operational issues, prolonging its life and ensuring that the system remains safe and reliable.

Working as an interface between the power source, the processor, and other components, the TPS3707-30D provides the power management features necessary for high- performance, low-power operation. Its primary task is to monitor the voltage level, current, and temperature of the various components in the system and then to provide advanced protection strategies if any of these factors exceeded the defined limits. Its advanced features allow the system designer to effectively and accurately establish required levels and timing to ensure optimal system performance and energy efficiency.

Application Fields

The TPS3707-30D is an ideal power management solution for a wide range of embedded systems, including applications in both traditional and modern designs. Its advanced features make it an excellent choice for applications requiring extended battery life, such as portable and mobile data systems. The superior system protection, fault detection, and advanced reset functions ensure that these systems remain durable and reliable. Additionally, the robust design makes the TPS3707-30D the ideal choice for medical and industrial environments, where a wide range of voltages and currents must be accurately controlled for optimal system performance. The low power consumption of the TPS3707-30D makes it ideal in automotive applications such as engine controllers, safety systems, and infotainment systems, which must provide optimal system performance while consuming minimal power.

Working Principle

The TPS3707-30D can be set with user-defined voltage and current limits according to the design requirements of the system. It then continuously monitors the system voltage and current to ensure these limits are not exceeded. When the voltage or current reaches the upper limit, the TPS3707-30D will signal a warning or issue a reset, depending on the voltage trip level. When the system is powered down, the TPS3707-30D will keep the system in standby mode until the power is restored.

If a fault condition is detected, the supervisor will immediately signal a warning and then either initiate a reset or shut down the system, depending on the system configuration. The user-defined reset threshold level for the TPS3707-30D ensures that the system remains safe and reliable. Additionally, the wide range of watchdog timeout periods enables the system designer to optimize system performance while retaining microsecond-level accuracy.

The advanced character of the TPS3707-30D also adds valuable performance features such as automatic power-down and auto-sleep. These features help conserve energy and prolong battery life to provide extended power supply for the system. The integrated delay circuit allows for improved timing accuracy and further enhances system safety and reliability.

Applications for the TPS3707-30D include handheld, battery-powered devices, portable or mobile computers, IoT devices, medical equipment, industrial machinery, and automotive systems. The TPS3707-30D provides robust protection with advanced features and low power consumption, making it the ideal choice for efficient and reliable power management in the most demanding applications.
