IPS4260LMTR

Power Distribution Switches, Load Drivers Overview

The IPS4260LMTR is a monolithic high-speed quad low-side intelligent power switch from STMicroelectronics, designed to drive up to four independent capacitive, resistive, or inductive loads. It operates within an 8 V to 50 V supply range and delivers a typical load current of 0.5 A per channel or 2 A on a single channel at Tamb=85°C. The device features integrated catch diodes for fast demagnetization, programmable current limitation via external resistors, and comprehensive diagnostics including open-load detection and thermal shutdown. Packaged in a thermally enhanced HTSSOP20.

Power Distribution Switches, Load Drivers Feature Summary

• Integrates four independent low-side channels with built-in overload protection and non-dissipative short-circuit cut-off capabilities.
• Provides extensive diagnostic feedback through common open-drain pins for open-load, overload, and thermal shutdown events.
• Supports fast demagnetization of inductive loads using integrated catch diodes combined with external TVS clamping.
• Includes ground and VCC wire-break protection alongside undervoltage lock-out for robust industrial operation.

Power Distribution Switches, Load Drivers Applications

• Servo drives and motor control systems
• Programmable Logic Controllers (PLCs) and industrial PC peripherals
• Smart Industry and Industry 4.0 manufacturing equipment
• General low-side switching for loads connected to positive supply

Power Distribution Switches, Load Drivers Procurement Notes

Verify the specific ordering suffix 'MTR' corresponds to the tape-and-reel packaging configuration required for automated assembly processes. Confirm that the component status aligns with long-term availability plans, as some variants may be marked obsolete or restricted. Ensure the selected package type matches the thermal management requirements of the target application design.

Power Distribution Switches, Load Drivers Selection Notes

Select this component when driving multiple inductive or resistive loads requiring individual channel protection and diagnostic reporting. The programmable current limit allows customization for varying load profiles without internal resistor adjustments. Consider the HTSSOP20 package for its thermal performance in compact industrial enclosures where space constraints are critical.
