PWM Input. Routes to output channel, dependent on output configuration settings.
PWM Input. Routes to output channel, dependent on output configuration settings.
Low-voltage ground. Connects to ground of circuitry providing PWM inputs. Both
PWMGND and PWMGND2 are to tie together to the same ground.
Overcurrent protection output, channel A output stage. Open drain, 16mA drive strength
output with pull-up. Pulls low when active from overcurrent detection of output stage.
Overcurrent protection output, channel B output stage. Open drain, 16mA drive strength
output with pull-up. Pulls low when active from overcurrent detection of output stage.
Overcurrent protection output, channel C output stage. Open drain, 16mA drive strength
output with pull-up. Pulls low when active from overcurrent detection of output stage.
Overcurrent protection output, channel D output stage. Open drain, 16mA drive strength
output with pull-up. Pulls low when active from overcurrent detection of output stage.
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.
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 (also see Note 8).
PWM power amplifier output, channel D.
High side boot strap input, output channel D. Capacitor couples to OUTD amplifier output.
High side boot strap input, output channel C. Capacitor couples to OUTC amplifier output.
PWM power amplifier output, channel C.
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 (also see Note 8).
Output stage C 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.
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.
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.
5V internal regulator filter connect. A +5V supply is internally generated from the voltage
source provided at the VDDHV pin. REG5V is used for external connection of a decoupling
capacitor.
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.
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 (also see Note 8).
PWM power amplifier output, channel B.
High side boot strap input, output channel B. Capacitor couples to OUTB amplifier output.
High side boot strap input, output channel A. Capacitor couples to OUTA amplifier output.
PWM power amplifier output, channel A.
