Note 1: All voltages are referenced to GND. Currents entering the IC are specified positive and currents exiting the IC are negative.
Note 2: Compensation of the internal sense resistor value for initial tolerance and temperature coefficient of -20°C to +70°C can
Note 3: Current sampling ceases for 2.5ms every 144ms to allow the ADC to measure temperature.
Note 4: Typical value for t
Note 5: Interface timing shown is for fast-mode (400kHz) operation. This device is also backward compatible with standard-mode
