Pin Description (continued)
PIN
NAME
FUNCTION
35
SRAD
Serial Address Bit. SRAD allows the serial address to be changed in case it conflicts with another serial
device. If SRAD = GND, A1 = 0. If SRAD = IN, A1 = 1.
36
RSO
Open-Drain Reset Output. Deasserts when V7 exceeds 2.55V (typ rising). Has 65ms delay before release.
RSO
is expected to connect to nRESET on the CPU.
37
MR
Manual Reset Input. A low input at
MR
causes the
RSO
output to go low and also resets the V3 output to its
default 1.3V setting.
MR
impacts no other functions.
38
CC3
REG 3 Compensation Node. Connect a series resistor and capacitor from CC3 to GND to compensate the
regulation loop. See the
Compensation and Stability
section
.
39
FB3
REG3 Feedback-Sense Input. Connect directly to the REG3 output voltage. Output voltage is set by the serial
interface.
40
ON6
On/Off Input for REG6. Drive high to turn on. When enabled, the REG6 output activates. ON6 has hysteresis
so an RC can be used to implement manual sequencing with respect to other inputs. It is expected that ON1,
ON2, and ON6 are connected to SYS_EN.
41
V6
Also known as VCC_USIM. Linear-regulator output. This voltage is programmable through the I
2
C interface to
0V, 1.8V, 2.5V, or 3.0V. The default voltage is 0V. REG6 is activated when ON6 is high.
42
IN6
Power Input to the V6 LDO. Typically connected to V1, but can also connect to IN.
43
PG1
REG1 Power Ground. Connect directly to a power-ground plane. Connect PG1, PG2, PG3, and GND
together at a single point as close to the IC as possible.
44
LX1
REG1 Switching Node. Connects to the REG1 inductor.
45
PV1
REG1 Power Input. Bypass to PG2 with a 4.7μF or greater low-ESR ceramic capacitor. PV1, PV2, PV3, and IN
must connect together externally.
46
ON1
On/Off Input for REG1. Drive high to turn on REG1. When enabled, the REG1 output soft-starts. ON1 has
hysteresis so an RC can be used to implement manual sequencing with respect to other inputs. It is
expected that ON1, ON2, and ON6 connect to SYS_EN.
47
SLP
Sleep Input.
SLP
selects which regulators ON1 and ON2 turn on.
SLP
= high is normal operation (ON1 and
ON2 are the enables for the V1 and V2 DC-DC converters).
SLP
= low is sleep operation (ON1 and ON2 are
the enables for the V1 and V2 LDOs).
48
DBI
Dual-Mode, Dead-Battery Input. Connect DBI to IN to set the dead-battery falling threshold to 3.15V (no
resistors needed). Connect DBI to a resistor-divider for an adjustable DBI threshold.
EP
EP
Exposed Metal Pad. Connect the exposed pad to ground. Connecting the exposed pad to ground does not
remove the requirement for proper ground connections to the appropriate ground pins.
