The power stage outputs can be configured as four half-bridge channels, two half-bridge channels and one full-bridge channel, two full-bridge channels, or one parallel full-bridge channel. The CS4412 integrates on-chip over-current, undervoltage, over-temperature protection and error reporting as well as a thermal warning indicator. The low RDS(ON) outputs can source up to 2.4 A peak current, delivering 85% efficiency. This efficiency provides for a small device package and lower power supplies. The CS4412 is available in a 48-pin QFN package in Commercial grade (-40 to +70° C). The CRD4412 customer reference design is also available.
