VTRACK (Pin 1): Supply Sense that VCC BATT Tracks when
above 3V. Must be
≤ VCC1.
VBACKUP (Pin 2): Back-Up Battery Input.
VCC1 (Pins 3, 10): Power Supply (2.5V to 5.5V). Both VCC1
pins must be connected externally to the 2.5V to 5.5V
supply.
PGOOD (Pin 4): Fault Report (Undervoltage). Open-drain
driver sinks current whenever LDO1, LDO2 or buck out-
puts are low.
ADD7 (Pin 5): I2C Strappable Address (Bit 7)—VCC1 or
ground.
SDA (Pin 6): I2C Data Input.
NC (Pin 7): Not Connected.
SCL (Pin 8): I2C Clock Input.
ADD6 (Pin 9): I2C Strappable Address (Bit 6)—VCC1 or
ground.
GND (Pin 11): Buck NFET Ground.
NC (Pin 12): Not Connected.
NC (Pin 13): Not Connected.
SW (Pin 14): Buck Regulator Switch.
RUN (Pin 15): Chip Enable. 1.5V enables the part. Forcing
this pin below 0.3V shuts down the device. In shutdown,
all functions are disabled, drawing <35
A supply current.
Do not leave RUN floating. Must be
≤ VCC1.
NC (Pin 16): Not Connected.
FB (Pin 17): Buck Regulator Feedback.
VCC BATT (Pin 18): VCC BATT PowerPath Output.
BATTFAULT (Pin 19): Open-Drain Output. It is low when
VCC1 is low.
LDO1FB (Pin 20): LDO1 Regulator Sense.
LDO1 (Pin 21): LDO1 Regulator Output.
VCC2 (Pin 22): LDO Regulator Supply Voltage.
LDO2 (Pin 23): LDO2 Regulator Output.
LDO2FB (Pin 24): LDO2 Regulator Sense.
Exposed Pad (Pin 25): Ground. Must be soldered to PCB
ground for electrical contact and optimum thermal
performance.
