CS5165H Datasheet | onsemi

feature rich design gives end users the maximum flexibility to implement the best price/performance solutions for their end products. The CS5165H has been carefully crafted to maximize performance and protect the processor during operation. It has a 5- bit DAC on board that holds a ±1.0% tolerance over temperature. Its on board programmable Soft Start insures a control start up, and the FET nonoverlap circuitry ensures that both FETs do not conduct simultaneously. The on board oscillator can be programmed up to 1.0 MHz to give the designer maximum flexibility in choosing external ponents and setting systems costs. The CS5165H protects the processor during potentially catastrophic events like overvoltage (OVP) and short circuit. The OVP feature is part of the V2 architecture and does not require any additional ponents. During short circuit, the controller pulses the MOSFETs in a “hiccup” mode (3.0% duty cycle) until the fault is removed. With this method, the MOSFETs do not overheat or self destruct. The CS5165H is designed for use in both single processor desktop and multiprocessor workstation and server applications. The IC can be powered from either single or dual 5.0 V, 12 V power supplies. The CS5165H’s current sharing capability allows the designer to build multiple parallel and redundant power solutions for multiprocessor systems. The CS5165H contains other control and protection features such as Power Good, ENABLE, and adaptive voltage positioning. It is available in a 16 lead SOIC wide body package.
