Absolute Maximum Ratings
VBATA, VBATB to GND............................................-0.3V to +20V
VCOMA to GND...................................... -0.3V to (VBATA + 0.3V)
VCOMB to GND......................................-0.3V to (VBATB + 0.3V)
VCHGA, VCHGB, VEXTLD, VACDET to GND...........-0.3V to +30V
VPDS, VDISA, VDISB to GND................-0.3V to (VEXTLD + 0.3V)
VDD, VBATSEL, VACPRES, VBATSTAT, VTCOMP,
VMINV to GND......................................................-0.3V to +6V
VTHMA, VTHMB (Note 1)..........................................-0.3V to +6V
Continuous Current out of THMA, THMB............................20mA
IACPRES, IBATSTAT Sink Current.........................................30mA
Continuous Power Dissipation (TA = +70°C)
20-Pin TSSOP (derate 7.0mW/°C above +70°C).........560mW
Operating Temperature....................................... -40°C to +85°C
Storage Temperature......................................... -65°C to +150°C
Lead Temperature (soldering, 10s).................................. +300°C
Note 1: Signals on THMA and THMB below -0.3V are clamped by internal diodes limit forward diode current to maximum continuous
current. When voltage on these pins is below -0.3V.
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 in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect
device reliability.
