General Description
The CS4412 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 CS4412 integrates on-chip over-current, under-
voltage, over-temperature protection and error report-
ing as well as a thermal warning indicator. The low
RDS(ON) outputs can source up to 2.4 A peak current,
delivering 85% efficiency. This efficiency provides for a
small device package and lower power supplies.
The CS4412 is available in a 48-pin QFN package in
Commercial grade (-40 to +70° C). The CRD4412 cus-
tomer reference design is also available. Please refer to
“Ordering Information” on page 22 for complete order-
ing information.

Pin Description
Over-current Reference (Input) - Sets over-current trip level. Connect pin through a resistor to
GND. See “Device Protection and Error Reporting” on page 17. This pins should not be left float-
ing.
Output Ramp Capacitor (Input) - Sets the output ramp time for half-bridge configured outputs.
Ground (Input) - Ground for the internal logic and I/O. These pins should be connected to the
common system ground.
High Voltage Output Power (Input) - High voltage power supply for the individual output power
half-bridge devices.
Power Ground (Input) - Ground for the individual output power half-bridge devices. These pins
should be connected to the common system ground.
PWM Output (Output) - Amplified PWM power half-bridge outputs.
Thermal Warning Output (Output) - Thermal warning output. Open drain, active low. See
“Device Protection and Error Reporting” on page 17.
Thermal and Under-voltage Error Output (Output) - Error flag for thermal shutdown and under-
voltage. Open drain, active low. See “Device Protection and Error Reporting” on page 17
Over-current Error Output (Output) - Over-current error flag for the associated outputs. Open
drain, active low. See “Device Protection and Error Reporting” on page 17.
Ramp-up/down Select (Input) - Set high to enable ramping. When set low, ramping is disabled.
See “PWM Popguard Transient Control” on page 13.
