STMicroelectronics IPS4140HQ-1, Quad Power Switch IC 48-Pin, QFN48L [IPS4140HQ-1]; 330-365

The STMicroelectronics IC are monolithic 4-channel drivers featuring very low RDS(on) and per-channel diagnostic. The ICs, realized in STMicroelectronics VI Power technology, are intended to drive any kind of load with one side connected to ground. Active channel current limitation combined with thermal shutdown, independent for each channel, and automatic restart, protect the device against overload.

Per channel short-circuit protection

Per channel over temperature protection

Thermal case protection

Not simultaneous channel reactivation at thermal case reset

All type of loads (resistive, capacitive, inductive load) are driven

Loss of GND protection

Under voltage shutdown with hysteresis

Overvoltage protection (VCC clamping)
