Product details

Overview

IPS1025HFQ from STMicroelectronics is a single-channel high-side switch IC designed for industrial load control, featuring 8.65–60 V supply range, 2.4 A continuous output current, 12 mΩ typical R_DS(ON) at 25 °C, <60 µs power-on propagation delay, and dual-threshold overload protection with smart capacitive-load driving. It serves as a protected power path controller in PLC I/O modules and NC machine tool interfaces.

For engineers reviewing the IPS1025HFQ datasheet, IPS1025HFQ pinout, IPS1025HFQ application, or IPS1025HFQ equivalent, key selection criteria include its case-temperature shutdown (130 °C), fast demagnetization capability (V_DEMAG = V_CC−72.5 V), dual diagnostic pins (FLT1/FLT2), and configurable IPD-based overcurrent threshold selection - all critical for SIL-compliant industrial safety architectures.

Technical Context

The device implements a thermally robust high-side power switch with two independent temperature monitoring paths: junction sensing (T_JSD = 150–190 °C shutdown) and case sensing (T_CSD = 130 °C shutdown), enabling layered thermal fault management. Its active clamp circuit enables fast demagnetization of inductive loads by pulling OUT to V_CC−V_DEMAG (68–76 V range), dissipating stored energy safely across internal switch and load resistance.

Overload response is programmable via the IPD pin: capacitor coupling enables dual-threshold operation (IPK_H = 15.4 A, ILIM_H = 9.0 A for ≤215×C_PD µs; IPK_L = 8.0 A, ILIM_L = 3.5 A thereafter), while resistor biasing selects fixed low- or high-threshold modes. Diagnostic outputs FLT1 (over-temperature) and FLT2 (overload) are open-drain current sources with 2–4 mA fault current and 200–550 µs blanking time.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CC Range	8.65 V to 60 V - supports wide industrial bus voltages including 24 V and 48 V systems without external regulation.
R_DS(ON)	12 mΩ typ. @ 25 °C, ≤25 mΩ @ 125 °C - enables 2.4 A continuous operation with <72 mW conduction loss at full load.
t_PD(VCCON)	<60 µs - meets Class 3 timing requirements for interface types C/D per IEC 61000-4-x immunity standards.
Overload Protection	Dual-threshold (IPK_H/IPK_L) with programmable duration - protects incandescent lamps and solenoids during inrush while sustaining steady-state loads.
Thermal Shutdown	Junction (150–190 °C) and case (130 °C) thresholds - prevents thermal runaway under sustained overload or poor heatsinking.
Demagnetization Voltage	V_CC−72.5 V (min) - clamps inductive kickback to safe levels, reducing external snubber requirements.
Diagnostic Pins	FLT1 (junction/case over-temp), FLT2 (overload) - 2–4 mA current-source outputs with 200–550 µs blanking, simplifying fault detection logic.

Pinout & Package

IPS1025HFQ is housed in a VFQFPN-48L package (8 mm × 6 mm × 0.9 mm), featuring an exposed thermal pad for enhanced heat dissipation (R_th(JC) = 1.0 °C/W). The 48-pin layout consolidates power, ground, diagnostics, and configuration functions with dedicated multi-pin parallel routing for high-current paths.

Pin/Terminal	Circuit Role	Design Meaning
OUT (Pins 17–24, 35–42)	Power stage output channel	All 16 pins must be shorted on PCB to handle 2.4 A continuous current and reduce trace inductance.
VCC (Pin 13)	Supply voltage input	Accepts 8.65–60 V; includes internal 70 V clamp (V_CLAMP) for transient overvoltage protection.
GND (Pin 6)	Device ground reference	Reference for all internal circuits; requires low-impedance connection to minimize noise coupling.
IN (Pin 17)	Logic input control	CMOS-compatible (V_IL ≤ 0.8 V, V_IH ≥ 2.2 V); hysteresis ensures noise immunity in industrial environments.
FLT1 (Pin 46)	Over-temperature diagnostic	Current-source output activated during junction or case over-temperature events; must not float.
FLT2 (Pin 13)	Overload diagnostic	Current-source output triggered by overcurrent; blanking time prevents false triggering during transients.
IPD (Pin 22)	Overcurrent threshold selector	Configures dual/single threshold mode via capacitor/resistor; floating = 1 µs IPK_H duration.

Key Features

Feature	Design Value
Smart capacitive-load driving	Programmable dual-threshold overload protection (IPK_H/IPK_L) prevents lamp filament damage during cold-start inrush.
Fast demagnetization	V_DEMAG = V_CC−72.5 V clamping enables <10 µs current decay in 10 mH inductive loads without external diodes.
Dual thermal protection	Independent junction (T_JSD) and case (T_CSD) sensors allow staged shutdown - junction first, then case - improving system uptime.
Ground disconnection detection	Monitors GND integrity via ILGND ≤ 0.5 mA leakage; forces output OFF if GND opens, preventing unsafe floating outputs.
IEC-compliant ESD/EMI immunity	Designed to meet IEC 61000-4-2 (ESD), -4-4 (EFT), and -4-5 (surge) - validated for harsh factory floor environments.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-side switch applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IPS1025HF	Same die, PowerSSO-24 package (R_th(JC) = 0.7 °C/W), lower thermal resistance but larger footprint.	Better suited for space-constrained designs where thermal performance outweighs board area.	Select when PCB layout allows larger 10.3×7.5 mm footprint and junction cooling dominates thermal design.
IPS2050H	Single-channel, 60 V, 2.5 A, but lacks dual thermal sensing and IPD-programmable thresholds; only single ILIM = 3.5 A.	Targeted at cost-sensitive applications without SIL requirements or complex inrush profiles.	Choose only if dual-threshold overload handling and case-temperature shutdown are not required.

Compared with IPS1025HF (PowerSSO-24), IPS1025HFQ offers superior board-level thermal management via VFQFPN-48L's 8×6 mm footprint and exposed pad, while IPS2050H sacrifices diagnostic granularity and smart load adaptation for lower BOM cost - making IPS1025HFQ optimal for SIL-aligned industrial control where reliability and configurability are non-negotiable.

FAQ

What is the maximum continuous output current rating for IPS1025HFQ?

The IPS1025HFQ is rated for 2.4 A continuous output current at T_C = 25 °C with proper PCB copper pour and thermal vias. At T_C = 125 °C, derating applies due to R_DS(ON) increase to ≤25 mΩ; actual current depends on thermal design but remains within safe SOA limits defined by junction temperature shutdown at 150–190 °C.

How does the IPD pin configure overload protection behavior?

The IPD pin selects overload response mode: connecting to GND via capacitor (470 pF–470 nF) enables dual-threshold operation (IPK_H = 15.4 A for DPK = 215×C_PD µs, then IPK_L = 8.0 A); connecting to IN via 220 kΩ resistor disables IPK_H; connecting to GND via 10 kΩ resistor disables IPK_L. Floating defaults to 1 µs IPK_H window.

Can FLT1 and FLT2 pins be tied together for simplified fault reporting?

No - FLT1 and FLT2 serve distinct fault categories (FLT1 = over-temperature, FLT2 = overload) and have independent blanking times (200–550 µs) and activation thresholds. Tying them risks masking simultaneous faults and violates recommended layout per DS13869 Section 7.3. Each pin must connect to separate MCU GPIOs or dedicated fault logic with appropriate pull-down resistors.

What is the purpose of the active clamp (demagnetization) function?

The active clamp rapidly dissipates energy stored in inductive loads (e.g., solenoids, relays) by pulling the OUT pin to V_CC−V_DEMAG (68–76 V below V_CC) during turn-off. This achieves faster current decay than passive snubbers, reduces voltage spikes, and eliminates need for external freewheeling diodes - critical for compact, high-density industrial drives.
