... APPLICATIONS 4.1 Overview The CS44130 is a high-efficiency power stage for digital Class-D amplifiers. It has been designed to be con- figured 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. ...

... Output Mode Configuration The CS44130 can be configured for several modes of operation. inputs and the corresponding mode of operation. These pins should remain static during operation (RSTx/y set high Output Mode Auto-Reset Latched Shutdown When an error condition occurs on a channel, that channel is shutdown until ...

... Protection and Error Reporting The CS44130 has built-in protection circuitry for over-current, under-voltage, and thermal warning/overload conditions. All error outputs are open-drain, active low, and can safely be tied together in any combination. These pins also have internal pull-up resistors, alleviating the need for external resistors. ...

... PWM input signal. 5.3 Recommended Power-Down Sequence 1. Set RSTx/y low. If the CS44130 is configured for ramping, the outputs will ramp down to PGND and then become HI-Z. If the CS44130 is not configured for ramping, the outputs will immediately become HI-Z. 2. Power-down the remainder of the system. ...

... POWER SUPPLY, GROUNDING, AND PCB LAYOUT The CS44130 requires a 3 5.0 V digital power supply for the core logic. In order to support a number of PWM frontend solutions, a separate VL power pin is provided to condition the interface signals to support up to 5.0 V lev- els. The VL power pins control the voltage levels for all PWM input, mode, and error reporting signals. ...
