Micrel has launched the MIC2310, a single-FET, constant power-limit hot-plug controller.
The device addresses power-limiting applications including blade server systems, base stations, high-reliability servers, +12 V power distribution backplanes, power-limiting applications, enterprise switch networks, and select telecommunications applications.
The device is suitable for 240 VA system applications specified by UL60950, EN60950, and CSA1950 industry specifications.
The controller has adaptive circuit breaker threshold control circuitry that maintains constant power product (V x A) at the output over the device’s full operating voltage range. The device is externally programmable for various power applications (50-600 W) and the voltage is monitored at load (output of the MIC2310) to provide true power limiting.
Integration of inrush current control circuitry lowers the external component count and a steady-state load current monitor allows the system manager (microcontroller) to allocate and/or prioritise available power for the downstream system circuits or modules.
The integrated controller is supplied as a 24-pin TSSOP package option.
