Hot Swappable I2C Isolator Enables Simple Interfacing Between Busses with Isolated Grounds

Thu, 22 Apr 2010 13:36:16 -0400

MILPITAS, CA — April 22, 2010 — Linear Technology introduces the LTC4310, a hot swappable I2C isolator that provides bidirectional communication between two I2C busses whose grounds are isolated from one another.

Overvoltage/Overcurrent Protection Controller Safeguards Sensitive Low Voltage Electronics from Input Power Surges

Wed, 21 Apr 2010 13:45:01 -0400

MILPITAS, CA — April 21, 2010 — Linear Technology Corporation introduces the LTC4361, a 2.5V to 5.5V overvoltage and overcurrent protection controller designed to safeguard low voltage, portable electronics from damaging input voltage transients and current surges. Overvoltage events can occur due to power adapter failure or faults, or when hot-plugging an AC adapter into the power input of the device. The wrong power adapter can also inadvertently be plugged into a device, potentially causing damage from overvoltage or negative supply voltage. The LTC4361 utilizes a 2% accurate 5.8V overvoltage threshold to detect an overvoltage event and responds quickly within 1µs (max) to isolate the downstream components from the input. Overvoltage protection of up to 80V can be achieved with this simple IC/MOSFET solution without the need of additional external components such as capacitors or transorbs at the input.
