Texas Instruments PCSD93501QRYCTQ1

CSD93501-Q1 is a highly optimized smart power stage for use in a high power, high density applications with 5V input, including automotive. This product integrates the driver IC and power MOSFETs in one silicon die to complete the power stage switching function. It also integrates the accurate current sensing and temperature sensing functionality to simplify system design and improve accuracy. The monolithic design enables high switching frequency with high efficiency, lower noise, and high current- and temperature-sensing accuracy. This product has a small 3.5 x 6.25 mm QFN package. The PCB footprint has been optimized to help reduce design time and simplify the completion of the overall system design.

CSD93501-Q1 provides key differentiating features including cycle-by-cycle current limiting/protection based on high-side FET current sense, over temperature protection, negative over current detection, and open pin detection, which improve system reliability.
