DESCRIPTION
1
nPDN
I
3.3
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.
2
OCFG1
I
3.3
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.
3
OCFG0
I
3.3
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.
4 PWMGND GND
0
Low-voltage ground. Connects to ground of circuitry providing PWM inputs. Both
PWMGND and PWMGND2 are to tie together to the same ground.
5 PWMVDD P
3.3
Low-voltage power. This 3.3V supply connects to the same system low-voltage power
used for providing PWM inputs.
6
nOVRT
O
3.3
Over-temperature warning output. Open drain, 16mA drive strength output with pull-up.
Pulls low when active from over-temperature detection.
7
PWM1
I
3.3
PWM Input. Routes to output channel, dependent on output configuration settings.
8
PWM2
I
3.3
PWM Input. Routes to output channel, dependent on output configuration settings.
9
PWM3
I
3.3
PWM Input. Routes to output channel, dependent on output configuration settings.
10 PWM4
I
3.3
PWM Input. Routes to output channel, dependent on output configuration settings.
11 PWM5
I
3.3
PWM Input. Routes to output channel, dependent on output configuration settings.
12 PWM6
I
3.3
PWM Input. Routes to output channel, dependent on output configuration settings.
