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.
Addtionally, it integrates error reporting for these events, as well any thermal warning events.
The low RDS(ON) of the out...
