6 / 69 page Pin Functions (continued) PIN I/O DESCRIPTION NAME NO. BAT A3, B3 I/O Battery Connection. Connect to the positive terminal of the battery. Bypass BAT to GND with at least 1 µF of ceramic capacitance. TS B4 I Battery Pack NTC Monitor. Connect TS to a 10-kΩ NTC thermistor in parallel to a 10-kΩ resistor. If TS function is not to be used connect a 5-kΩ resistor from TS to ground. PG B1 O Open-drain Power Good status indication output. The PG pin can also be configured as a general purpose open drain output or level shifter version of MR. VIO E1 I System IO supply. Connect to system IO supply to allow level shifting of input signals (SDA, SCL, LP and CE) to the device internal digital domain. Connect to VDD when external IO supply is not available. NC1 C3 I No Connect. Connect to ground if possible for better thermal dissipation or leave floating. Do not connect to a any voltage source or signal to avoid higher quiescent current. NC2 C4 I No Connect. Connect to ground if possible for better thermal dissipation. May be shorted to /LP for easier routing as long as Absolute Maximum Rating requirements are met..
