Switch–to–Ground Input 4 (Source Output)
19
SG5
Switch–to–Ground Input 5 (Source Output)
20
SG6
Switch–to–Ground Input 6 (Source Output)
21
SP4
Programmable – Switch–to–Battery or Switch–to–Ground Input 4 (Source or Sink Output)
22
VBG
Bandgap Voltage. A bandgap reference is used to set up the reference and bias currents for the device.
A resistor must be connected from this pin to ground.
23
CSB
Chip Select Input. Input with internal active pull–up. Requires 5.0 V CMOS logic levels. Communication
with the device using SPI is enabled when the CSB pin is a logic 0.
24
SCLK
Serial Clock. SCLK is used to shift data into and out of the device. It transitions 1 time per bit with an
operation frequency, fSCLK, with a 50% duty cycle. SCLK is idle between commands and should be
commanded low.
