The address pin is biased either to VDD_CAP or GND. When
communicating with the SMS66 over the 2-wire bus A2 provides a
mechanism for assigning a unique bus address.
Programmable active high/low input. When asserted the RST output will be
go active. When de-asserted the RST output will go inactive immediately
after a reset timeout period (t
PRTO
) if there are no RST trigger sources active.
This timeout period makes it suitable to use a pushbutton for manual reset.
Programmable active high/low input signals the start of the power
sequencing. When asserted the part will sequence the supplies on and
when de-asserted the part will sequence the supplies off.
Programmable active high/low input. Force shutdown is used to immediately
turn off all converter enable signals (PUP outputs)
Programmable active high/low open drain Fault output. Active when a
programmed fault condition exists on AIN1, AIN2, or the internal temperature
sensor.
Programmable active high/low open drain Healthy output. Active when all
programmed power supply inputs and monitored inputs are within OV and
UV limits.
Programmable active high/low open drain Reset output. Active when a
programmed fault condition exists on any power supply inputs or monitored
inputs or when MR is active. RST has a programmable timeout period with
options for 0.64ms, 25ms, 100ms and 200ms.
