Battery Voltage Sense – Connect directly to positive terminal of battery
and bypass with a 2.2uF or greater capacitor.
Trickle Charge – Connect directly to positive terminal of battery.
Charge Current Sense – Connect directly to positive terminal of battery.
No Connect (may be connected to GND for easier routing of Ball D2).
Status Indicator.
Battery Thermistor Sense.
VDD Bypass – Connect to VDD bypass capacitor with 1uF or greater
capacitor.
Analog Ground – Connect to isolated PCB ground.
Ground – Connect to isolated PCB ground.
Voltage Input (+4.35V to +6.5V) – Bypass with a 2.2uF or greater
capacitor.
Enable Input – Apply a logic-high voltage to enable and/or resume
charging. After assertion of the EN signal, the safety timers start
counting from the beginning. When unused, this pin should be tied to
GND (do not leave floating).
Two-level charge current adjustment. Connect to VDDCAP for full
charge current. Connect to GND for 40mA. When unused, this
pin should be tied to VDDCAP (do not leave floating).
