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.
