Table 4
shows power modes in which the ISP1582 can be operated.
[1]
Power supply to the IC (V
CC
) is 3.3 V. Therefore, if the application is bus-powered, a 3.3 V regulator
needs to be used.
V
CC(I/O)
= V
CC
. If the application is bus-powered, a voltage regulator needs to be used.

Power-sharing mode
As can be seen in
Figure 12
, in power-sharing mode, V
CC
is supplied by the output of
the 5 V-to-3.3 V voltage regulator. The input to the regulator is from V
BUS
. V
CC(I/O)
is
supplied through the power source of the system. When the USB cable is plugged in,
the ISP1582 goes through the power-on reset cycle. In this mode, OTG is disabled.
The processor will experience continuous interrupt because the default status of the
interrupt pin when operating in sharing mode with the V
BUS
not present is LOW. To
overcome this, implement external V
BUS
sensing circuitry. The output from the voltage
regulator can be connected to pin GPIO of the processor to qualify the interrupt from
the ISP1582.
Remark:
When the core power is removed, the ISP1582 must be reset using the
RESET_N pin. The reset pulse width must be 2 ms.
