STMicroelectronics IPS4260L Quad Low-Side Intelligent Power Switch

STMicroelectronics IPS4260L Quad Low-Side Intelligent Power Switch is a monolithic, high-speed device designed to drive up to four independent capacitive, resistive, or inductive loads with one side connected to supply voltage. The IPS4260L features four integrated inductive catch diodes, which 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 overload protection, which limits the output current in case of overload.

The STMicroelectronics IPS4260L Quad Low-side Intelligent Power Switch allows an external resistor to set the overload current limitation level (ICOLIM) on the ILIM pin. Built-in thermal shutdown protects the IPS4260L against overtemperature even in case of short-circuit. If enabled, the integrated cut-off protection features non-dissipative protection in case of overload; it limits the output average current value, and consequently, the device overheats. Cut-off delay/restart can be programmed by external resistors on a 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) and four open drains on each INx pin (overload and thermal shutdown) feature an extensive diagnostic of the IPS4260L.
