IPS4260LTR

IPS4260LTR is a quad low-side intelligent power switch. It is a monolithic high speed (FSW up to 250kHz) switch. The channels can be parallelized to reduce power dissipation. When connected to Vcc rail, four integrated catch diodes clamp the turn-off transients generated by inductive loads even with huge inductance. Each channel is protected against overload or short circuit event. The intervention level can be set by an external resistor on ILIM pin. Built-in thermal shutdown protects the chip against over temperature in case of short-circuit. The integrated cut-off protection features a non-dissipative protection in case of overload. It limits both the output average current value and device overheating. Cut-off delay/restart can be programmed by external resistors on CoD pin. This power switch is useful in programmable logic control, industrial PC peripheral input/output, numerical control machines, general low-side switch applications.
