ISP1109
USB transceiver with carkit support
If the Power-down is because of the setting of register bit PWR_DN in the Mode
Control register, the bias will be enabled if the V
BUS
voltage goes above the
SESS_VLD threshold. Note: In this case, make sure bit SESS_VLD_IEH in the
Interrupt Enable High register is set to logic 1 before the PWR_DN bit is set. The
recommended sequences for software is:
a. Set bit SESS_VLD_IEH to logic 1
b. Set bit PWR_DN to logic 1
c. Wait for interrupt from the ISP1109
d. If INT_N is asserted, read the Interrupt Latch register
e. If bit SESS_VLD_INT is logic 1, clear bit PWR_DN (Note: Software must clear
bit PWR_DN within 5 ms from the time pin INT_N is asserted. For details,
see
Section 10
).
Pin ISET will remain LOW when V
CC
is below V
th(ISET)
. Pin ISET can also be controlled by
software through register bits. If bit ISET_DRV_EN is set to logic 1, the status of the ISET
pin will be determined by bit ISET_STATE.
