Highly Integrated Quad Low-Side Switch from STMicroelectronics Presents Rich Diagnostics for Smart Automation

The STMicroelectronics IPS4260L quad low-side intelligent power switch boosts efficiency and reliability in industrial automation, with four 260mΩTYP RDS(ON) power switches and protection features in a space-efficient, thermally enhanced package. The IC can manage up to [email protected]=85°C (0.6A per channel or 2.4A on a single channel) with the possibility to set current limitation threshold by an external resistor and to parallelize the channel. 

The very low rise and fall time (tr, tf < 1μs) allows high switching frequency (up to 250kHz) and makes it ideal for servo drives, motor controls, industrial-PC peripherals, programmable logic controllers (PLCs), and general low-side switching of loads connected to the positive supply. The IPS4260L provides rich diagnostics for Smart Industry/Industry 4.0 smart-manufacturing applications.

The diagnostic features include open-load detection that operates while outputs are in the off state, which prevents hazards due to failures such as wire breaks. In addition, current limiting with non-dissipative cut-off shuts down the output stage after a user-selectable period in the event of over-current. An external resistor determines the limiting period, and restart is attempted automatically.

In order to ensure quick response even with inductive loads (such as motors), ST’s new power switch integrates a smart architecture for fast demagnetization feature based on a single external clamp diode shared between the four channels.

Further diagnostic features include two common open-drain pins for indicating open-load and overload/thermal-shutdown, and four input/output open-drain pins for per channel overload/thermal-shutdown signalization.

An extensive ecosystem supports the IPS4260L as a member of ST’s extensive family of intelligent power switches. It includes a dedicated graphical user interface (STSW-IFP029GUI) for configuring the device, a detailed user manual (UM2297), and the STEVAL-IFP029V1 highly developed evaluation board. The board meets international safety standards for industrial equipment, with galvanic isolation between logic and power stages, reverse-polarity protection, and compliance with EMC regulations and IEC61000-4 specifications.

 The IPS4260L is in production now, in miniaturized HTSSOP20 Thermally Enhanced Thin Shrink Small-Outline Package, priced from $1.58 for orders of 1000 pieces.
