Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur.

See the table below for Operating Conditions.

Note 2: Supply voltage is limited in AM Mode due to additional power dissipation of output stage when

operating in Class B mode. Please note that the TPS4100A is still fully protected from load dump transients in AM

Mode.

Note 3

(AGND). Please note that pins 5, 11, and 12 are outputs and can be damaged if a voltage is forced externally.

Note 4: Human body model, 100pF discharged through a 1.5K

Ω resistor.

Note 5: Machine model, 220pF – 240pF discharged through all pins.

Note 6: Recommended Operating Conditions indicate conditions for which the device is functional.

See Electrical Characteristics for guaranteed specific performance limits.

Note 7: Supply voltage is limited in AM Mode due to additional power dissipation of output stage when

operating in Class B mode, as opposed to Switching Mode.
