[1] For a high-side switch, the load pin voltage goes negative with respect to the ground during the turn-off of an inductive load. This
negative voltage is clamped by the device.
[2] 9 V ≤ VBG ≤ 35 V
[3] This is the current drawn from the supply when both inputs are LOW, and includes leakage current to the loads.
[4] Defined as in ISO10483-1. For comparison purposes only.
[5] This only applies to the RBLon per channel. The supply and input voltages for the RBLon tests are continuous. The specified pulse
duration is tp = 300 µs, and refers only to the applied load current.
[6] RG is a resistor incorporated internally into the package.
[7] 5.5 V ≤ VBG ≤ 35 V
[8] An open circuit load can be detected in the off-state and requires an external pull-up resistor, RL(oc).
[9] See Table 3 “Truth table”
[10] Overtemperature protection is not active during reverse current operation.
[11] Undervoltage sensor causes each output channel to switch off and reset.
[12] Overvoltage sensor causes each output channel to switch off to protect the load.
[13] After cooling below the reset temperature the channel will resume normal operation.
[14] The status output is an open drain transistor and requires an external pull-up resistor, RS, to indicate a logic HIGH.
