BQ27546-G1 Product details

Description
The bq27546-G1 Li-Ion battery fuel gauge is a
microcontroller peripheral that provides fuel gauging
for single-cell Li-Ion battery packs. The device
requires minimal system microcontroller firmware
development for accurate battery fuel gauging. The
bq27546-G1 resides within the battery pack or on the
system’s main-board with an embedded battery (nonremovable).
The bq27546-G1 uses the patented Impedance Track™ algorithm for fuel gauging, and provides
information such as remaining battery capacity
(mAh), state-of-charge (%), run-time to empty (min.),
battery voltage (mV), and temperature (°C). It also
provides detections for internal short or tab
disconnection events.
The bq27546-G1 features integrated support for
secure battery pack authentication, using the SHA-
1/HMAC authentication algorithm.
The device comes in a 15-ball Nano-Free™ DSBGA
package (2.61 mm × 1.96 mm) that is ideal for space- constrained applications.
