Power-down and mute input. Active low. When this input is low, all 4 outputs become
inactive and their output stages float, and their output is muted. Internal logic and other
references remain active during this power-down state.
Output configuration control select. OCFG0 and OCFG1 are logic inputs to select the
output configuration mode of the output stages. Connects to either PWMGND ground or
PWMVDD (+3.3V) through nominal 10kΩ resistor to select output configuration.
Output configuration control select. OCFG0 and OCFG1 are logic inputs to select the
output configuration mode of the output stages. Connects to either PWMGND ground or
PWMVDD (+3.3V) through nominal 10kΩ resistor to select output configuration.
Low-voltage ground. Connects to ground of circuitry providing PWM inputs. Both
PWMGND and PWMGND2 are to tie together to the same ground.
Low-voltage power. This 3.3V supply connects to the same system low-voltage power
used for providing PWM inputs.
Over-temperature warning output. Open drain, 16mA drive strength output with pull-up.
Pulls low when active from over-temperature detection.
PWM Input. Routes to output channel, dependent on output configuration settings.
