Serial address select pins. Used to assign unique SMBus address to each IC or to enable certain
management features.
Current limit select. Sets the overcurrent threshold voltage for ISENA and ISENB.
Configuration pin. Used to setup current sharing and non-linear response.
Serial clock. Connect to external host and/or to other ZL devices.
Serial data. Connect to external host and/or to other ZL devices.
Serial alert. Connect to external host if desired.
Loop compensation configuration pins.
Output voltage selection pins. Used to set V OUT set-point and V OUT max.
Undervoltage lockout selection. Sets the minimum value for V DD voltage to enable V OUT .
Soft start pin. Sets the output voltage ramp time during turn-on and turn-off. Sets the delay from when EN
is asserted until the output voltage starts to ramp.
