PIN FUNCTIONS
ADIN: ADC Input. The onboard ADC measures voltage
range between 0V and 2.048V. Tie to GND if unused.
ADR1, ADR0: I2C Device Address Inputs. Connecting
ADR1 and ADR0 to VIN, GND or leaving the pins open
configures one of nine possible addresses. See Table 1
in the Applications Information section for details.
Exposed Pad (DD Package Only): Exposed pad may be
left open or connected to device ground (GND).
GND: Device Ground.
SCL: I2C Bus Clock Input. Data is shifted in and out at
the SDA pin on rising edges of SCL. This pin is driven
by an open-collector output from a master controller. An
external pull-up resistor or current source is required and
can be placed between SCL and VIN. The voltage at SCL
is internally clamped to 6V (5.5V minimum).
SDA (LTC4151 Only): I2C Bus Data Input/Output. Used for
shifting in address, command or data bits and sending
out data. An external pull-up resistor or current source
is required and can be placed between SDA and VIN.
The voltage at SDA is internally clamped to 6V (5.5V
minimum).
SDAI (LTC4151-1/LTC4151-2 Only): I2C Bus Data Input.
Used for shifting in address, command, data, and SDAO
acknowledge bits. This pin is driven by an open-collector
outputfromamastercontroller.Anexternalpull-upresistor
or current source is required and can be placed between
SDAI and VIN. If the master separates SDAI and SDAO,
data read at SDAO needs to be echoed back to SDAI for
properI2Ccommunication.ThevoltageatSDAIisinternally
clamped to 6V (5.5V minimum).
SDAO (LTC4151-2 Only): Serial Bus Data Output. Open-
drain output used for sending data back to the master
controller or acknowledging a write operation. Normally
tied to SDAI to form the SDA line. An external pull-up
resistor or current source is required.
SDAO (LTC4151-1 Only): Inverted Serial Bus Data Out-
put. Open-drain output used for sending data back to the
mastercontrolleroracknowledgingawriteoperation.Data
is inverted for convenience of opto-isolation. An external
pull-up resistor or current source is required.
SENSE+: Kelvin Sense of the VIN Pin. See Figure 10 for
recommended Kelvin connection.
SENSE: High Side Current Sense Input. Connect an
external sense resistor between SENSE+ and SENSE.
The differential voltage between SENSE+ and SENSEis
monitored by the onboard ADC with a full-scale sense
voltage of 81.92mV.
