Press Release Summary:
Low voltage Model LTC4216 allows safe insertion and removal of boards from live backplane. Together with analog current limit amplifier, electronic circuit breaker with adjustable response time provides dual level overcurrent protection. Adjustable soft-start circuitry limits rate of change of inrush at start-up. Offered in 10-lead MSOP and 12-lead DNF packages, Model LTC4216 meets demands of microprocessor systems with low voltage implementations.
Original Press Release:
Ultra Low Voltage Hot Swap Controller for Ultra Low Voltage Microprocessors
Milpitas, CA - March 15, 2005 - Linear Technology Corporation introduces the LTC4216, an ultra low voltage Hot Swap(TM) controller that protects load voltages ranging from 0V to 6V. In order to meet demands for faster and more efficient data processing, modern microprocessor systems are designed with lower voltage implementations. The LTC4216 answers the in- rush control needs of such systems and allows for the safe insertion and removal of boards from a live backplane. Together with an analog current limit amplifier, an electronic circuit breaker with adjustable response time provides dual level overcurrent protection. The IC also features an adjustable soft-start circuitry to limit the rate of change of the inrush current at start-up.
The Feedback pin monitors the output supply voltage and signals the RESET# output. The ON pin enables the part, while the FAULT# indicates that the circuit breaker had tripped due to an overcurrent fault. Together they can configure the device to automatically retry.
The LTC4216 is offered in 10-lead MSOP and 12-lead (3mm x 4mm) DFN packages, and an attractive solution for today's servers, telecom equipment and base station, whose low voltage design is driven by the increasing complexity and operating speeds of low power microprocessors.
Specified over the commercial and industrial temperature ranges, the LTC4216 is available from stock and pricing starts at $1.85 each for 1,000 pieces quantities.
