3 Description
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.
