LTC2934CDC-1#TRPBF Datasheet/PDFPMIC (Power Management Integrated Circuit) generally refers to an integrated circuit system that combines all power management functions, also known as a power management integrated circuit system. PMICs are ubiquitous in major electronic products, and are used to supply and collect related electric power, providing current and voltage to microprocessors and other circuits, which is beneficial to reduce the costs of the device while optimizing the performance. Supervisors, which is one kind of PMIC, control and supervise systems by generating reset signals.
The LTC2934CDC-1#TRPBF is a general-purpose supervisor designed to monitor, supervise, and protect power systems. It makes use of a precision, high-accuracy voltage monitoring circuit to monitor the main power input. The LTC2934CDC-1#TRPBF can output a reset signal if it falls out of the required voltage range, and its reset signal can provide an active-low reset output for up to 720ms, giving enough time for the system to back up the data and provide a reliable shutdown.
The LTC2934CDC-1#TRPBF can sense a wide range of supply voltages from 0.9V to 10V, so it is a great choice for flexibility and high precision operation. The available supply current is 20uA, and its’ sleep mode will allow it to draw only 2uA standby current. It also offers multiple monitoring choices : voltage window/window clear, under/over voltage, power-on reset, manual reset, power-good reset, warning output. The programmable reset delay can be adjusted up to 10ms to supports many system reset scenarios. In addition, the supply voltage tracking feature allow the reset threshold to follow the input voltage and prevent false reset, which is great for applications that rely on brown-out or transients.
LTC2934CDC-1#TRPBF is commissioned to many applications, such as ASIC/FPGA power surveillance, high power battery management system, Brownout/Transient protection, back-up power supply, low battery warning, data center management. It is specially designed for applications that need long reset pulse and high accuracy voltage monitoring capability, giving it a tremendous advantage over other supervisors. Its low current consumption and small size make the LTC2934CDC-1#TRPBF the perfect choice for portable devices and even small electronics.
In conclusion, the LTC2934CDC-1#TRPBF is designated as an excellent cost-performance ratio power supervisor in PMIC’s supervisors product line. It offers low power consumption, high accuracy, flexible reset/warning signals, wide voltage range and various monitoring options, making it an ideal choice for almost any electronic device.
