DESCRIPTION

3.3

Output configuration selection input, and power supply sync output. Upon device reset, pin operates as input,

using application-installed pull-up or pull-down connection to pin to specify one of 4 amplifier configurations.

Upon internal D2-45057, D2-45157 firmware execution, pin becomes output, providing synchronizing signal

to on-board power supply circuits. When operating as output, provides 4mA drive strength. Note: This pin may

also be referenced as “PSTEMP” on some reference designs. Function is identical regardless of name.

3.3

PWM protection input. Input has hysteresis. Protection monitoring functionality of pin is controlled by internal

D2-45057, D2-45157 firmware, and dependent on which of the 4 amplifier configurations is enabled.

3.3

Overcurrent protection output, channel A output stage. Open drain 16mA driver, with internal 100kΩ (approx.)

pull-up. Pulls low when active from overcurrent detection of output stage.

3.3

Overcurrent protection output, channel B output stage. Open drain 16mA driver, with internal 100kΩ (approx.)

pull-up. Pulls low when active from overcurrent detection of output stage.

3.3

Overcurrent protection output, channel C output stage. Open drain 16mA driver, with internal 100kΩ (approx.)

pull-up. Pulls low when active from overcurrent detection of output stage.

3.3

Overcurrent protection output, channel D output stage. Open drain 16mA driver, with internal 100kΩ (approx.)

pull-up. Pulls low when active from overcurrent detection of output stage.

HV

Output stage D high voltage supply power. A separate power pin connection is provided for each of the output

stages. All of the HVDD[A:D] pins and the VDDHV pin connect to the system “HV” power source.

HV

Output stage D high voltage supply ground. A separate ground pin connection is provided for each of the

output stages. All of the HGND[A:D] pins connect to system “HV” power ground (see Note 15).

PWM power amplifier output, channel D.

HV

High-side boot strap input, output channel D. Capacitor couples to OUTD amplifier output.

HV

High-side boot strap input, output channel C. Capacitor couples to OUTC amplifier output.

HV

PWM power amplifier output, channel C.

HV

Output stage C high voltage supply ground. A separate ground pin connection is provided for each of the

output stages. All of the HGND[A:D] pins connect to system “HV” power ground (see Note 15).

stages. All of the HVDD[A:D] pins and the VDDHV pin connect to the system “HV” power source.

3.3

“Subwoofer” channel PWM output, with 16mA drive strength. Connects to filter network for supplying line-

level analog output to subwoofer.

Do not connect to this pin.

-

Overcurrent reference analog input. Used in setting the overcurrent error detect externally-set threshold. The

pin needs to be connected to a 100kΩ resistor to ground to set the overcurrent threshold according to the

specified limits.

+HV High Voltage internal driver supply power. All of the HVDD[A:D] pins and the VDDHV pin connect to the system

“HV” power source. The internal +5V supply regulators also operate from this VDDHV input.

5

5V internal regulator filter connect. A +5V supply is internally generated from the voltage source provided at

the VDD pin. REG5V is used for external connection of a decoupling capacitor.

HV

Output stage B high voltage supply power. A separate power pin connection is provided for each of the output

stages. All of the HVDD[A:D] pins and the VDDHV pin connect to the system “HV” power source.

HV

Output stage B high voltage supply ground. A separate ground pin connection is provided for each of the

output stages. All of the HGND[A:D] pins connect to system “HV” power ground (see Note 15).

HV

PWM power amplifier output, channel B.
