5 / 27 page bq24401 www.ti.com SLUS497A – SEPTEMBER 2001 – REVISED MARCH 2010 ABSOLUTE MAXIMUM RATINGS (1) VALUE UNIT VCC VCC relative to VSS –0.3 to 7 V VT DC voltage applied on any pin, relative to VSS –0.3 to VCC V TOPR Operating ambient temperature –20 to 70 °C TSTG Storage temperature –40 to 125 °C TSOLDER Soldering temperature (10 s max.) 260 °C (1) Permanent device damage may occur if Absolute Maximum Ratings are exceeded. Functional operation should be limited to the Recommended DC Operating Conditions detailed in this data sheet. Exposure to conditions beyond the operational limits for extended periods of time may affect device reliability. DC THRESHOLDS (1) TA = TOPR; VCC = 5V ±20% (unless otherwise specified) PARAMETER TEST CONDITIONS TYPICAL TOLERANCE UNIT VTCO Temperature cutoff Voltage at the TS pin 0.225 × VCC ±5% V VHTF High-temperature fault Voltage at the TS pin 0.25 × VCC ±5% V VLTF Low-temperature fault Voltage at the TS pin 0.5 × VCC ±5% V VMCV Maximum cell voltage Voltage at the BAT pin 2.00 ±2.5% V VLBAT Minimum cell voltage Voltage at the BAT pin 950 ±5% mV VTherm TS input change for ΔT/Δt detection Voltage at the TS pin –VCC/161 ±25% V/min VSNSHI High threshold at SNS Voltage at the SNS pin 50 ±10 mV VSNSLO Low threshold at SNS Voltage at the SNS pin –50 ±10 mV VSLP Sleep-mode input threshold Voltage at the BAT pin VCC–1 ±0.5 V (1) All voltages are relative to VSS except as noted.
