PINTYPEDESCRIPTION
NAMENUMBER
P21OLED 2 or Not Used (connect to VSS)
VEN2OActive High Voltage Translation Enable. This signal is optionally used to switch the input voltage divider on/off to reduce the power consumption (typ 45 µA) of the divider network. If not used, then this pin can be left floating or tied to VSS.
P13OLED 1 or Not Used (connect to VSS). This pin is also used to drive an LED for single-LED mode. Use a small signal N-FET (Q1) in series with the LED as shown on Figure 8-4.
BAT4ITranslated Battery Voltage Input
CE5IChip Enable. Internal LDO is disconnected from REGIN when driven low.
REGIN6PInternal integrated LDO input. Decouple with a 0.1-µF ceramic capacitor to VSS.
REG257P2.5-V output voltage of the internal integrated LDO. Decouple with 1-µF ceramic capacitor to VSS.
VSS8PDevice ground
SRP9IAnalog input pin connected to the internal coulomb-counter peripheral for integrating a small voltage between SRP and SRN where SRP is nearest the BAT– connection.
SRN10IAnalog input pin connected to the internal coulomb-counter peripheral for integrating a small voltage between SRP and SRN where SRN is nearest the PACK– connection.
P6/TS11IPack thermistor voltage sense (use a 103AT-type thermistor)
P5/HDQ12I/OOpen-drain HDQ Serial communication line (target). If not used, then this pin can be left floating or tied to VSS.
P4/SCL13ITarget I2C serial communication clock input. Use with a 10-kΩ pullup resistor (typical). This pin is also used for LED 4 in the four-LED mode. If not used, then this pin can be left floating or tied to VSS.
P3/SDA14I/OOpen-drain target I2C serial communication data line. Use with a 10-kΩ pullup resistor (typical). This pin is also used for LED 3 in the four-LED mode. If not used, then this pin can be left floating or tied to VSS.
