The TI  BQ27542DRZR-G1 lithium-ion battery power monitoring meter, which is a microcontroller peripheral that can provide power

monitoring for a single lithium-ion battery pack.The device enables accurate battery power monitoring and requires minimal firmware

development for system microcontroller development.The power monitor resides in the battery pack or on the system motherboard with a

built-in battery (not removable).This power monitoring meter uses the patented Impedance Track™ algorithm for power monitoring, and

provides the battery surplus power (%), battery life (minutes), battery voltage (mV), and temperature (C) information.The device also provides

a detection function for internal short circuit or battery terminal disconnection events.The power monitor also features unique integrated

support capabilities for safe battery pack authentication (using the SHA-1 / HMAC authentication algorithm).

TI BQ27542DRZR-G1 Minimum operating temperature (Min) -40℃, maximum operating temperature (Max) 85℃, its output voltage

is 2.5 V, using small 12 pins 2.50mmx 4.00mm small external size lead-free (SON) package.

The broad fan of BQ27542DRZR-G1 was applied to; smartphones, tablets, digital and video cameras, handheld terminals, MP3,

multimedia player.
