IPS4260L

Power Distribution Switches, Load Drivers Overview

The IPS4260L is a monolithic high-speed quad low-side intelligent power switch designed by STMicroelectronics. It drives four independent capacitive, resistive, or inductive loads connected to a positive supply within an 8 V to 50 V operating voltage range. The device integrates four channels with typical RDS(ON) of 260 mΩ, supporting up to 0.6 A per channel or 2.4 A on a single channel at TAMB=85°C. It features fast switching times (tr, tf <1 μs) and supports frequencies up to 250 kHz. Built-in protections include programmable current limiting via external resistor, non-dissipative short-circuit protection, thermal shutdown, and wire break detection.

Power Distribution Switches, Load Drivers Procurement Notes

Verify the specific ordering suffix (e.g., MTR for tape-and-reel, LM for tube) as it determines packaging and availability status. Confirm current lifecycle status, as some variants may be obsolete or restricted. Ensure compatibility with required thermal management solutions given the HTSSOP20 package constraints. Cross-reference official datasheets for exact electrical parameters against application requirements before finalizing procurement decisions.

Power Distribution Switches, Load Drivers Selection Notes

Select this component when driving multiple inductive or resistive loads from a single positive rail requiring individual channel protection. Choose based on the need for programmable current limiting and fast decay times for inductive loads. Consider the HTSSOP20 package for space-constrained designs needing enhanced thermal performance. Verify that the external resistor values for current limit and cut-off delay meet the specific system timing and protection requirements.

Power Distribution Switches, Load Drivers Part Context

The IPS4260L belongs to STMicroelectronics' industrial intelligent power switch family, designed for harsh environments. It complements other IPS devices like the IPS2050H and ISO8200 series in expansion boards such as X-NUCLEO-OUT07A1. The device supports Smart Industry applications through rich diagnostics and is often paired with STM32 microcontrollers and IO-Link transceivers for advanced automation control.

Power Distribution Switches, Load Drivers Replacement Considerations

Check for direct pin-compatible substitutes within the IPS4260 series or similar quad low-side switches from ST. Verify if alternative packages or suffixes offer equivalent electrical characteristics. Ensure any replacement maintains compliance with IEC 61131-2 standards if used in PLC applications. Consult official substitution guides for lifecycle-managed parts.
