It monitors remaining capacity, voltage, current, and temperature for one Li-Ion cell, communicating results over HDQ or I²C to a host processor. The 15-DSBGA package is sized for space-constrained portable designs — handheld instruments, medical monitors, and IoT edge nodes where battery runtime reporting drives the user experience.
No NRND or last-time-buy notice applies, so it is safe to qualify into new designs.
