The LTC2951CTS8-2#TRMPBF is a type of power supply controller, monitor and supervisor. It is used in systems that require regulated power sources and where distortion or undervoltage may occur. The power device allows for power sequencing, sequencing control and multiple switch configurations.

The device is designed to monitor, protect and control a wide variety of point-of-load and intermediate voltage an power up and down sequencing. The LTC2951CTS8-2#TRMPBF utilizes voltage monitoring, failure detection and reset generator into a single low cost chip. It can be used for a variety of applications such as automotive, telecommunications, factory automation, medical, industrial and consumer electronic applications.

The core of the LTC2951CTS8-2#TRMPBFpower device is the voltage monitor, reset timer, switch and 5-bit digital to analog converter (DAC). The voltage monitor constantly monitors and compares two split sources (VmonA and VmonB) against analog voltage reference. When either of the sources exceed the voltage reference, an internal OPU pin is activated and the device enters monitor mode.The device provides a variety of protection functions including overvoltage protection, undershoot/overvoltage protection, and overcurrect protection. The reset timer provides voltage supervisor function, which triggers a reset to ASIC/μP after destructive event such as overvoltage, lack of sequencing, or incorrect sequencing.

The switchin the LTC2951CTS8-2#TRMPBF power device is used for sequencing, sequencing control and powering on/off. The DAC can be set to control any of the four on/off switches and provide an accurate voltage reference for power up/down sequencing.

The LTC2951CTS8-2#TRMPBF device is available in 8-pin mini-mold and 8-pin TSOP packages, allowing it to be easily mounted onto any PCB or heat sink. The chip is also specified by a variety of environmental conditions, including -40°C to +85°C temperature range, 0.8V-5.5V supply voltage, 2.5V to 6.0V VmonA/VmonB differential input voltage, 2.5V to 5.5V VSW voltage range, and 0.8V-5.5V Vper voltage range.

In summary, the LTC2951CTS8-2#TRMPBF is a power device originally intended for Power Supply Controllers, Monitors. The device monitors, protects and controls a wide variety of point-of-load and intermediate voltage sources, preventing undervoltage and distortion. It contains a voltage monitor, reset timer, switch and 5-bit digital to analog converter (DAC) and is available in 8-pin mini-mold and 8-pin TSOP packages.
