General Description
The CS4412A is a high-efficiency power stage for digital
Class-D amplifiers designed to input PWM signals from
a modulator such as the CS4525. The power stage out-
puts 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 CS4412A integrates on-chip over-current, under-
voltage, over-temperature protection and error report-
ing as well as a thermal warning indicator. The low
R
DS(ON)
outputs can source up to 2.5 A peak current,
delivering high efficiency which allows small device
package and lower power supplies.
The CS4412A is available in a 48-pin QFN package in
Commercial grade (-10 to +70° C). The CRD4412A cus-
tomer reference design is also available. Please refer to
“Ordering Information” on page 24 for complete order-
ing information.
