7.3 Power supply configurations
The ISP1105/1106 can be used with different power supply configurations, which can
be changed dynamically. An overview is given in
Normal mode — Both V
For 5 V operation, V
voltage regulator then produces 3.3 V for the USB connections. For 3.3 V operation,
both V
independently connected to a voltage source (1.65 V to 3.6 V), depending on the
supply voltage of the external circuit.
Disable mode — V
connected. In this mode, the internal circuits of the ISP1105/1106 ensure that the
(D , 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
this mode, the (D , D ) pins are made three-state and the ISP1105/1106 allows
external signals of up to 3.6 V to share the (D D ) lines. The internal circuits of the
ISP1105/1106 ensure that virtually no current (maximum 10 A) is drawn via the (D
D ) lines. The power consumption through pin V
(suspended) state level. Both the VP and VM pins are driven HIGH to indicate this
mode. Pin RCV is made LOW. Some hysteresis is built into the detection of V
