MAX5930A/MAX5931A/MAX5931B
The MAX5930A/MAX5931A/MAX5931B turn off the cor-
responding channel if any of the above conditions are
not met. During a fault condition on a given channel
only, the affected channel is disabled. After a fault-
latched shutdown, recycle the corresponding ON_
inputs to unlatch and restart only the corresponding
channel.
Startup Period
R
TIM
sets the duration of the startup period from 0.4ms
(R
TIM
= 4kΩ) to 51ms (R
TIM
= 500kΩ) (see the
Setting
the Startup Period, R
TIM
section). The default startup
period is fixed at 9ms when TIM is unconnected. The
startup period begins after the turn-on conditions are
met as described in the
Mode
section, and the device
is not latched or in its autoretry delay (see the
Latched
and Autoretry Fault Management
section).
