Product details

Overview

IPS4260L from STMicroelectronics is a quad-channel low-side intelligent power switch IC designed for industrial I/O control, featuring independent 0.5 A per channel (2 A single-channel) current capability, 8–50 V operating range, <1 μs switching transitions, and integrated non-dissipative cut-off protection programmable via external resistors on ILIM and CoD pins. It drives inductive, resistive, or capacitive loads in PLC output modules and CNC machine interfaces with built-in demagnetization clamping and wire-break protections.

For engineers reviewing the IPS4260L datasheet, IPS4260L pinout, IPS4260L application, or IPS4260L equivalent, this device is selected for high-reliability industrial low-side switching where per-channel diagnostics (OL/FLT), thermal independence, fast decay support via VZ TVS configuration, and IEC 61131-2 compliance are required - not for generic load switching or automotive use.

Technical Context

The IPS4260L integrates four independent N-channel DMOS power stages in low-side configuration, each with dedicated current-sense and thermal monitoring circuitry. Its architecture supports parallel channel operation to reduce R_DS(ON)-related dissipation and enables fast demagnetization of inductive loads via dual VZ clamp pins configurable with external TVS diodes for either slow or fast decay modes.

Protection logic includes programmable current limiting (via ILIM resistor), time-limited cut-off (via CoD resistor), junction overtemperature shutdown (160 °C, 20 °C hysteresis), open-load detection in off-state (V_OLoff = V_CC−3.5 V), and coordinated GND/VCC wire-break response - all reported through open-drain diagnostic pins (FLT, OL, INx).

Key Specifications

Parameter	Value and Actual Design Meaning
V_CC Range	8 V to 50 V - supports wide industrial supply rails including 24 V DC and 48 V DC systems without external regulation.
R_DS(ON) (Typ)	260 mΩ @ 25 °C - enables ≤0.5 A continuous per channel at <1 W dissipation without heatsink under typical conditions.
Switching Speed	t_r/t_f < 700 ns - ensures clean digital timing for high-frequency PWM up to 250 kHz in valve or solenoid control.
Current Limit Accuracy	±30% - set by R_ILIM (30–120 kΩ); e.g., 60 kΩ yields 1.0 A nominal limit per channel.
Cut-off Delay	t_coff = R_CoD/120 ms - programmable from ~0.5 ms (60 kΩ) to 2 ms (240 kΩ); disabled when CoD shorted to SGND.
Thermal Shutdown	160 °C junction, 20 °C hysteresis - provides autonomous recovery after fault removal without system reset.
Diagnostic Pins	FLT (common thermal/cut-off), OL (common open-load), plus 4x INx (per-channel fault reporting) - enables granular fault isolation in multi-I/O systems.

Pinout & Package

IPS4260L uses a thermally enhanced HTSSOP20 package with exposed pad (SGND) for improved heat dissipation. PGND (pins 1,2,19,20) and SGND (pin 8 + exposed pad) must be connected on PCB but routed on separate ground planes to minimize noise coupling.

Pin/Terminal	Circuit Role	Design Meaning
IN1–IN4	Channel input / per-channel fault output	Open-drain logic inputs accepting 2.0 V high; also sink fault current during thermal/cut-off events on corresponding OUTx.
OUT1–OUT4	Low-side power stage outputs	N-channel DMOS drains - connect load between OUTx and V_CC; support paralleling for higher current or redundancy.
VZ (pins 3,18)	Clamp diode cathodes	Must be shorted externally; connection to V_CC enables slow decay; TVS to V_CC or PGND enables fast decay for inductive loads.
ILIM	Current limit programming	Analog input referenced to SGND; sets I_LIM = 60/R_ILIM[kΩ] A (30–120 kΩ range); no shared connection across multiple ICs.
CoD	Cut-off delay programming	Analog input referenced to SGND; sets t_coff = R_CoD/120 ms; short to SGND disables cut-off, leaving only thermal shutdown.
OL	Common open-load diagnostic	Open-drain output active low when any channel detects open load or short-to-ground in OFF state (INx = LOW).
FLT	Common fault diagnostic	Open-drain output active low during thermal shutdown or cut-off on any channel - logic OR of all four channels.

Key Features

Feature	Design Value
Four thermally independent channels	Each channel shuts down autonomously at 160 °C without affecting others - critical for mixed-load industrial I/O where one solenoid may overheat while others remain operational.
Non-dissipative cut-off protection	Programmable time-limited current limiting avoids thermal runaway during sustained overload - eliminates need for external current-sense amplifiers or complex feedback loops.
VZ-configurable demagnetization	Dual VZ pins allow selection of slow decay (VZ tied to V_CC) or fast decay (TVS between VZ and V_CC/PGND) - matches mechanical response requirements of valves, brakes, or actuators.
Wire-break detection	Simultaneous GND and V_CC disconnection triggers immediate channel disable and diagnostic assertion - prevents uncontrolled load behavior during field wiring faults.
IEC-compliant ESD/EMC robustness	Designed to meet IEC 61000-4-2 (±8 kV contact), -4-4 (4 kV), and -4-5 (2 kV surge) - reduces need for external transient suppression in harsh factory environments.

Industrial PC Peripheral I/O

Factory Automation Safety Interface

Use Scenario: Adding ruggedized digital output capability to IPC-based HMI systems controlling conveyor belts, sensors, and status indicators in packaging lines.

Equivalent & Alternatives

The following parts are listed as comparable options for similar quad low-side intelligent power switch applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IPS4260H	Same pinout and feature set, but rated for 60 V max V_CC (vs. 50 V) and higher R_DS(ON) (320 mΩ typ) - optimized for higher-voltage industrial buses.	Preferred for 48 V DC systems with margin; less suitable for 24 V high-current applications due to higher conduction loss.	Select when V_CC exceeds 50 V or when higher avalanche energy (EAS = 1.2 J) is required for aggressive inductive load switching.
VND5E025AK	Single-channel 2.5 A smart high-side switch; lacks VZ clamp, cut-off programming, and common OL/FLT pins - requires four devices for quad functionality.	Used in high-side configurations where load grounding is fixed; no native support for fast decay or open-load in off-state.	Choose only if high-side topology is mandatory or if per-channel design flexibility outweighs integration and diagnostic advantages of IPS4260L.

Compared with IPS4260H, the IPS4260L offers tighter R_DS(ON) and lower V_CC ceiling for optimized 24 V efficiency; versus VND5E025AK, it delivers true quad integration with unified diagnostics, eliminating board space and interconnect complexity in multi-output I/O designs.

FAQ

What is the maximum continuous current per channel under forced-air cooling?

The IPS4260L supports 0.5 A continuous per channel at ambient temperature with natural convection (R_TH(JA) = 43 °C/W). With 200 LFM airflow reducing thermal resistance to ~25 °C/W, junction temperature remains below 125 °C at 0.8 A per channel - verified per DS12305 Rev 7 Section 3 thermal data and Table 4 derating curves.

Can the VZ pins be left unconnected?

No - VZ pins (3 and 18) must be shorted together on the PCB and connected either directly to V_CC, or via a TVS/Zener to V_CC or PGND. Leaving them floating activates internal clamp diodes with limited fast-decay capability and risks exceeding EAS rating during large inductive transients - per Section 2.3 and Table 2 absolute ratings.

How does open-load detection work in OFF state?

When INx = LOW, the IC sources 20 μA (I_PU) into OUTx. If the load is disconnected, OUTx voltage drops below V_OLoff (V_CC−3.5 V), triggering OL/INx fault. A pull-down resistor R_PD < (V_CC−4.5 V)/20 μA ensures reliable detection - detailed in Section 6.4 and Equation 3 of DS12305 Rev 7.

Is the IPS4260L compatible with 3.3 V logic controllers?

Yes - its INx pins accept VIH ≥ 2.0 V and exhibit 0.4 V hysteresis (Table 7), making them fully compatible with 3.3 V CMOS outputs. No level-shifting is needed; series resistors (recommended per Section 2.4) protect against ESD and limit fault current during diagnostics.
