This IC contains two of these power switches (low-side switches). In case of inductive loads the integrated clamp diodes clamp the discharging voltage. If a “high” signal is applied to the enable input both switches can be activated independently of one another with TTL signals at the control inputs (active high). The high impedance inputs should always be connected to a fixed potential (noise immunity). The status output (open collector) signals the following malfunctions with high potential: q q q q q Overload, Open load, Shorted load to ground, Overvoltage, Overtemperature.
