From Linear Technology, the LTC4216 is an ultra low-voltage hot-swap controller that protects load voltages ranging from 0 V to 6 V. 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 (3-mm × 4-mm) 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 1000-pieces quantities.
