Energy-Harvesting Charger and Protector
Cell Input. Connect to the positive terminal of the cell without a bypass capacitor.
Charge Input. The IC charges the cell from the power source applied to this pin. Connect to the
output of the boost circuit or directly to a 4.21V or higher charge source.
Boost Enable. The boost circuit is enabled by driving this pin above the FB
the boost circuit is disabled by driving this pin below FB
Device Ground. Connect to system ground.
Boost Input. Controls current drive through inductor of external boost circuit.
Power Ground. Connect to system ground.
Active Enable. Pulse high to enable high-power regulator output. Pulse low to disable regulator
output.

applications.
Regulator Voltage Select. Ground this pin to select a regulator output voltage of 2.3V, leave
disconnected for a regulator output voltage of 3.3V, or connect to the BATT pin for a regulator
output voltage 1.8V.
Regulator Output. Connect to load circuit.
Low-Current Enable. Pulse high to enable the low-current regulator output after the high-current
regulator output is already active. Pulse low to disable.
Protected Output of Pack. Connect an external 10FF or greater capacitor to PCKP to support energy
buffering to the load, especially in low-temperature applications. PCKP is used for pulsed current
storage.
Exposed Pad. Connect to GND.
