Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 3: If voltage on pin D exceeds the diode select threshold the
LTC2996 uses the internal diode sensor.
Note 4: Remote diode temperature, not LTC2996 temperature.
Note 5: Guaranteed by design and test correlation.
Note 2: All currents into pins are positive; all voltages are referenced to
GND unless otherwise noted.
