CHARGER BLOCK: Input power for power path manager, connect to external DC supply. Connect external 1 μF (minimum) to AC 10 I GND Input power for power path manager, connect to external voltage from a USB port. Connect external 1 μF 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 10 μF from these pins to GND AVDD6 1 O Internal “always-on”-voltage. Connect a 4.7 μF 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. SDAT 27 I/O Data line for the I2C interface.
