The RTQ1950 provides enterprise-level protection and high-performance monitoring for 10V to 80V systems, such as 48/54V datacenter network equipment. Sub-μs response to short-circuit faults, high-resolution current limit programmability, and remote temperature sensing with adjustable warning/shutdown thresholds allow the RTQ1950 to protect and monitor the most critical systems. Programmable MOSFET SOA protection accurately controls maximum MOSFET power dissipation while MOSFET health warning and detection algorithms monitor the MOSFET even when fully enhanced. An adjustable fault timer avoids false trips and limits the duration of overload events.For monitoring, the RTQ1950 measures real-time power, voltage, current, temperature and fault data, and transmits this information via an I2C/SMBus interface with PMBus compliant command structure. Precision telemetry enables intelligent power management functions (e.g. Intel PROCHOT output), power optimization and early fault detection. The RTQ1950 also improves system diagnostics with adjustable telemetry averaging and peak power measurement.The RTQ1950 is pin-to-pin compatible with similar products in the market (TSSOP-28 9.7×4.4mm2 package), offering many improvements and advantages. The recommended junction temperature range is -40°C to 125°C.
