General Description

Space-Efficient Thermally-Enhanced QFN

No External Heat Sink Required

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.

Thermal Warning and Overload

Under-Voltage

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

outputs can source up to 2.5 A peak current,

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
