7.3 Power supply configurations
The ISP1104 can be used with different power supply configurations, which can be
changed dynamically.

voltage source (1.65 V to 3.6 V), depending on the supply voltage of the external
circuit.
Disable mode — V
the internal circuits of the ISP1104 ensure that the D and D pins are in three-state
and the power consumption drops to the low-power (suspended) state level. Some
hysteresis is built into the detection of V
Sharing mode — V
the USB mode and other modes when sharing the V
D are made three-state and the ISP1104 allows external signals of up to 3.6 V to
share the D and D lines. The internal circuits of the ISP1104 ensure that virtually
no current (maximum 10 A) is drawn via the D and D lines. The power

LOW to indicate this mode. Some hysteresis is built into the detection of V
