4.4.5 Power and System Management
Name Pin # Description I/O
Type I/O
Level Power
Domain PU / PD Comments
BATLOW# S156 Battery low indication to Module. Carrier to float the
line in inactive state. I OD
CMOS 1.8V Runtime PU 10K
Driven by OD on Carrier.
Pulled up on module.
CARRIER_PWR_ON S154 Carrier board circuits (apart from power management
and power path circuits) should not be powered up
until the Module asserts the CARRIER_PWR_ON signal. O
CMOS 1.8Vsb / 1.8V - 1.8Vsb is only used for signaling, not a power
source to the module
CARRIER_STBY# S153 The Module shall drive this signal low when the system
is in a standby power state. O
CMOS 1.8Vsb / 1.8V -
CHARGER_PRSNT# S152 Held low by Carrier if DC input for battery charger is
present. I OD
CMOS 1.8V Runtime PU 4.7K
Driven by OD on Carrier.
Pulled up on module.
CHARGING# S151 Held low by Carrier during battery charging. Carrier to
float the line when charge is complete. I OD
CMOS 1.8V Runtime PU 4.7K
Driven by OD on Carrier.
Pulled up on module.
VIN_PWR_BAD# S150 Power bad indication from Carrier board. Module and
Carrier power supplies (other than Module and Carrier
power supervisory circuits) shall not be enabled while
this signal is held low by the Carrier. I OD
CMOS 1.8V Runtime PU 2.2K
Driven by OD on Carrier
Module must implement PU but actual value is
depended on particular module design.
SLEEP# S149 Sleep indicator from Carrier board. May be sourced
from user Sleep button or Carrier logic. Carrier to float
the line in in-active state.Active low, level sensitive.
Should be de-bounced on the Module. I OD
CMOS 1.8V Runtime PU 4.7K Driven by OD on Carrier.
Pulled up on module.
LID# S148 Lid open/close indication to Module. Low indicates lid
closure (which system may use to initiate a sleep
state). Carrier to float the line in in-active state. Active
low, level sensitive. Should be de-bounced on the
Module. I OD
CMOS 1.8V Runtime PU 4.7K Driven by OD on Carrier.
Pulled up on module.
POWER_BTN# P128 Power-button input from Carrier board. Carrier to float
the line in in-active state. Active low, level sensitive.
Should be debounced on the Module. I OD
CMOS 1.8V Runtime PU 4.7K Driven by OD on Carrier.
Pulled up on module.
RESET_OUT# P126 General purpose reset output to Carrier board. O
CMOS 1.8V Runtime
RESET_IN# P127 Reset input from Carrier board. Carrier drives low to
force a Module reset, floats the line otherwise. I OD
CMOS 1.8V Runtime PU 4.7K
Driven by OD on Carrier.
Pulled up on module.
