¹Parameters are tested at 135°C. Values at 150°C are guaranteed by design or correlation.

²For input and output current specifications, negative current is defined as coming out of (sourcing) the specified device pin.

³High side on. As V_SXdecreases, fault occurs if V_BAT-V_SX>V_STG

⁴Low side on. As V_SXincreases, fault occurs if V_SX-V_LSS>V_STB

⁵V_STGthreshold is V_DTSTH+ V_STGO. V_STBthreshold is V_DTSTH+V_STBO.

⁶Function is correct but parameters not guaranteed above or below general limits (7 to 45 V).
