CS44130
General Description
The CS44130 is a high-efficiency power stage for digital Class-D amplifiers designed to recieve 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 protection for over-current, under-voltage, and over-temperature events. Addtion-
ally, it integrates error reporting for these events, as well any thermal warning events. The low R
of the outputs
DS(ON)
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 commercial grades (-10° to +70° C). The CRD44130-FB is
also available for device evaluation and implementation suggestions. Please refer to
