PIN FUNCTIONS

SENSE (Pin 1): Positive Current Sense Input and Power

the pin defaults to alert mode conforming to the SMBus

alert response protocol. It behaves as an open-drain logic

outputthatpullstoGNDwhenanythresholdregistervalue

isexceeded. Whenconﬁguredasachargecompleteinput,

connect to the charge complete output from the battery

charger circuit. A high level at CC sets the value of the

accumulated charge (registers C, D) to FFFFh.

Supply. Connect to the load/charger side of the sense

resistor. ꢀ

operating range is 2.7ꢀ to ±.±ꢀ.

SENSE

GND (Pin 2, Exposed Pad Pin 7): Device Ground. Connect

directly to the negative battery terminal. Exposed pad may

be left open or connected to device ground.

SCL (Pin 3): Serial Bus Clock Input.

SENSE (Pin 6): Negative Current Sense Input. Connect

SDA (Pin 4): Serial Bus Data Input and Output.

AL/CC (Pin 5): Alert Output or Charge Complete Input.

Conﬁgured either as an SMBus alert output or charge

completeinputbycontrolregisterbitsB[2:1].Atpower-up,

remain within ±±5mꢀ in normal operation. SENSE is also

the input for the ADC in voltage measurement mode.
