36V Nano Current Voltage Monitor Targets Multicell Applications
Linear Technology Corporation introduces the LTC2960, a 2.5V to 36V, two input voltage monitor that draws only 850nA of quiescent current, offering extended battery life in battery-powered applications. The LTC2960 provides two adjustable monitoring inputs that can be configured to provide undervoltage (UV) or overvoltage (OV) monitoring, low battery indication, undervoltage lockout (UVLO), power supply sequencing signals or a high voltage window...
No-Opto 100V Isolated Monolithic Flyback Regulator - Operates over a -55°C to 150°C Junction Temperature Range
Linear Technology has announced the high reliability (MP-grade) version of the LT3512, a high voltage isolated monolithic flyback regulator that operates over a -55°C to 150°C junction temperature range. This device simplifies the design of an isolated DC/DC converter. The LT3512 requires no optocoupler, third winding or signal transformer for feedback, as the device’s output voltage is sensed from the primary-side flyback signal.
Quad Independent Resistor Networks with Guaranteed CMRR Matching of 0.005% from -40°C to 125°C
Linear Technology introduced the LT5400, its first family of precision matched resistors designed for high performance signal conditioning applications in difference amplifiers, precision dividers, references and bridge circuits.
Single/Dual/Quad/Octal Precision Voltage Monitors Guaranteed to +125°C
Linear Technology has introduced a family of single, dual, quad, and octal voltage monitors that guarantee operation across -40°C to +125°C. The LTC2910, LTC2912, LTC2913 and LTC2914 all feature a threshold accuracy of ±1.5% over the automotive temperature range, allowing them to accurately monitor single channel point-of-load or multi-channel applications. These voltage monitors are all offered in tiny leaded and leadless packages and draw ve...
Quad & Single LTPoE++ PSE Controllers Deliver Up to 90W
Linear Technology Corporation introduces the LTC4266A and LTC4274A, 4-port and single-port Power over Ethernet (PoE) controllers for Power Sourcing Equipment (PSE), delivering up to 90W of power to Powered Devices (PDs). The current IEEE standard, 802.3at (also known as PoE+), limits the maximum available power to PDs to 25.5W. By the time the standard was ratified in 2009, applications were already demanding higher power levels. The LTC4266A and...
