Product Summary

The BQ27000DRKR is a single cell li-ion and li-pol battery gas gauge IC. This IC monitor a voltage drop across a small current sense resistor connected in series with the battery to determine charge and discharge activity of the battery. Compensations of the BQ27000DRKR for battery temperature, self-discharge, and discharge rate are applied to the capacity measurments to provide available time-to-empty in-formation across a wide range of operating conditions. The applications of the BQ27000DRKR include: PDA, Smart Phones, MP3 Players, Digital Cameras, Internet Appliances, Handheld Devices.

Parametrics

BQ27000DRKR absolute maximum ratings: (1)VCC Supply voltage (with respect to VSS): -0.3 to 7 V; (2)VIN Input voltage SRP, SRN, RBI, BAT (all with respect to VSS): -0.3 to VCC+0.3 V; HDQ, SCL, SDA, GPIO (all with respect to VSS): -0.3 to 7 V; PGM (with respect to VSS)during EEPROM programming: -0.3 to 22 V; (3)ISINK Output sink current GPIO, SCL, SDA, HDQ: 5 mA; (4)TA Operating free-air temperature range: -20 to 70 ℃; (5)Tstg Storage temperature range: -65 to 150 ℃; (6)TJ Operating junction temperature range: -40 to 125 ℃; (7)Lead temperature (soldering, 10 sec): 300 ℃.
