3 / 41 page  bq27541-V200 www.ti.com SLUSA11 – FEBRUARY 2010 ELECTRICAL SPECIFICATIONS ABSOLUTE MAXIMUM RATINGS over operating free-air temperature range (unless otherwise noted) (1) VALUE UNIT VI Regulator input, REGIN –0.3 to 24 V VCC Supply voltage range –0.3 to 2.75 V VIOD Open-drain I/O pins (SDA, SCL, HDQ) –0.3 to 6 V VBAT BAT input, (pin 4) –0.3 to 6 V VI Input voltage range to all others (pins 1, 7, 8, 9) –0.3 to VCC + 0.3 V Human Body Model (HBM), BAT pin 1.5 ESD kV Human Body Model (HBM), all pins 2 TF Functional temperature range –40 to 100 °C Tstg Storage temperature range –65 to 150 °C (1) Stresses beyond those listed under absolute maximum ratings may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under recommended operating conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. DISSIPATION RATINGS PACKAGE(1) TA ≤ 40°C DERATING FACTOR RqJA POWER RATING TA ≤ 40°C 12-pin DRZ(2) 482 mW 5.67 mW/°C 176°C/W (1) For the most current package and ordering information, see the Package Option Addendum at the end of this document, or see the TI website at www.ti.com. (2) This data is based on using a 4-layer JEDEC high-K board with the exposed die pad connected to a Cu pad on the board. The board pad is connected to the ground plane by a 2- × 2-via matrix. RECOMMENDED OPERATING CONDITIONS TA = -40°C to 85°C; typical values at TA = 25°C and V(REGIN) = VBAT = 3.6 V (unless otherwise noted) MIN TYP MAX UNIT No operating restrictions 2.7 5.5 VI Supply voltage, REGIN V No FLASH writes 2.45 2.7 Fuel gauge in NORMAL mode. ICC Normal operating mode current (1) 131 mA ILOAD > Sleep Current Fuel gauge in SLEEP mode. I(SLP) Low-power operating mode current(1) 60 mA ILOAD < Sleep Current Fuel gauge in FULLSLEEP mode. I(FULLSLP) Low-power operating mode current(1) 21 mA ILOAD < Sleep Current Fuel gauge in HIBERNATE mode. I(HIB) Hibernate operating mode current (1) 6 mA ILOAD < Hibernate Current Output voltage low (HDQ, SDA, SCL, VOL IOL = 3 mA 0.4 V SE) VOH(PP) Output high voltage (SE) IOH = –1 mA VCC–0.5 V External pull-up resistor connected VOH(OD) Output high voltage (HDQ, SDA, SCL) VCC–0.5 V to Vcc VIL Input voltage low (HDQ, SDA, SCL) –0.3 0.6 V VIH Input voltage high (HDQ, SDA, SCL) 1.2 6 V V(A1) Input voltage range (TS) VSS–0.125 2 V V(A2) Input voltage range (BAT) VSS–0.125 5 V V(A3) Input voltage range (SRP, SRN) VSS–0.125 0.125 V Ilkg Input leakage current (I/O pins) 0.3 mA tPUCD Power-up communication delay 250 ms (1) Specified by design.
