C address selection. This pin can be either left open, tied to V
DDI
, or grounded through
a 10 k
resistor.
27
EN1
Enable 1
Enable 1 Input. The combination of the logic state of the Enable 1 and Enable 2 inputs
determine operation mode and type of power sequencing of the IC.
28
EN2
Enable 2
Enable 2 Input. The combination of the logic state of the Enable 1 and Enable 2 inputs
determine operation mode and type of power sequencing of the IC.
29
RT
Reset Timer
This pin allows programming the Power-ON Reset delay by means of an external RC
network.
30
RESET
Reset Overbar
The Reset Control circuit monitors both the switching regulator and the LDO feedback
voltages. It is an open drain output and has to be pulled up to some supply voltage (e.g.,
the output of the LDO) by an external resistor.
31
CLKSEL
Clock Selection
This pin sets the CLKSYN pin either as an oscillator output or synchronization input pin.
The CLKSEL pin is also used for the I
2
C address selection.
32
CLKSYN
Clock Synchronization
Oscillator output/synchronization input pin.
