The IPS4260L is a monolithic high speed (FSW = 100 kHz) device, which can drive four independent capacitive, resistive or inductive loads with one side connected to supply voltage. Four integrated inductive catch diodes clamp the turn-off transients generated by inductive loads combined with proper external TVS allowing fast decay even with huge inductance. Each channel is protected by the overload protection limiting the output current in case of overload. The IC allows the overload current limitation level (ICOLIM) to be set by an external resistor on ILIM pin. Built-in thermal shutdown protects the chip against overtemperature even in case of short-circuit. If enabled, the integrated cut-off protection features a non-dissipative protection in case of overload; it limits both the output average current value and, consequently, the device overheating. Cut-off delay/restart can be programmed by external resistors on CoD pin; it can be disabled by shorting CoD to GND. Two common diagnostic open drains pins (OL, for open load and FLT for overload and thermal shutdown) together with the four open drain on each INx pin (overload and thermal shutdown) feature an extensive diagnostic of the chip.
