I/O DESCRIPTION
NAME NO.
CHARGER BLOCK:
Input power for power path manager, connect to external DC supply. Connect external 1μF (minimum) to
AC 10 I
GND
Input power for power path manager, connect to external voltage from a USB port. Connect external 1μF
USB 12 I
(minimum) to GND. Default input current limit is 500 mA max
BAT 5,6 O Charger power stage output, connect to battery. Place a ceramic capacitor of 10μF from these pins to GND
AVDD6 1 O Internal “always-on”-voltage. Connect a 4.7μF cap from AVDD6 to GND
System voltage; output of the power path manager. All voltage regulators are typically powered from this
SYS 7, 8 O
output.
Temperature sense input. Connect to NTC thermistor to sense battery pack temperature. TPS6507x can be
internally programmed to operate with a 10k curve 2 or 100k curve 1 thermistor. To linearize the thermistor
TS 11 I
response, use a 75k (for the 10k NTC) or a 360k (for the 100k NTC) in parallel with the thermistor. Default
setting is 10k NTC
ISET 9 I Connect a resistor from ISET to GND to set the charge current.
SCLK 28 I Clock input for the I2C interface.
