Power Stage Supports Multiple Output Configurations

The CS44130 is a high-efficiency power stage for digital Class-D amplifiers designed to input PWM signals from a modulator such as the CS44800/600. 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 CS44130 integrates on-chip over-current, under-voltage, over-temperature protection and error reporting as well as a thermal warning indicator. The low RDS (ON) of the outputs allows the part to operate at up to 90% efficiency. This efficiency provides for a smaller device package, no heat sink requirements, and smaller power supplies. The CS44130 is available in a 48-pin QFN package for both Commercial grades (-10° to +70° C) and Automotive grades (-40° to +85° C).
