Product details

Overview

IPS1025HQ-32 from STMicroelectronics is a high-side switch IC designed for industrial load control, featuring 8–60 V supply range, 5.6 A steady-state output current (per datasheet Table 10), ≤25 mΩ R_DS-ON at T_J = 125 °C, dual-threshold overload protection (IPK_H = 25.1 A, ILIM_H = 17.9 A typ.), and integrated junction/case over-temperature shutdown (T_JSD = 170 °C, T_CSD = 130 °C). It drives inductive, resistive, or capacitive loads in programmable logic controllers and CNC machines.

For engineers reviewing the IPS1025HQ-32 datasheet, IPS1025HQ-32 pinout, IPS1025HQ-32 application, or IPS1025HQ-32 equivalent, key selection criteria include its VFQFPN-48L 8×6×0.9 mm package, smart capacitive-load driving via IPD-configurable thresholds, fast demagnetization (V_DEMAG = V_CC−72.5 V), diagnostic FLT1/FLT2 current-source pins, and IEC 61000-4-2/4-4/4-5 compliance.

Technical Context

This device implements a thermally robust high-side power switch with dual independent thermal monitoring: junction temperature sensing triggers output disable at 170 °C and resets at 150 °C, while case temperature sensing activates at 130 °C and resets at 110 °C. The active clamp circuit enables fast demagnetization of inductive loads by pulling OUT to V_CC−72.5 V during turn-off.

Overload protection operates in three configurable modes via the IPD pin: dual-threshold (IPK_H/ILIM_H + IPK_L/ILIM_L), single-low (IPK_L = 13.1 A, ILIM_L = 8.0 A typ.), or single-high (IPK_H = 25.1 A, ILIM_H = 17.9 A typ.). Diagnostic outputs FLT1 and FLT2 are open-drain current sources (−4.0 mA sink at V_FLT = 1 V) with 200–550 µs blanking time.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CC Range	8 V to 60 V - supports wide industrial rail voltages including 24 V and 48 V systems without external regulation.
I_OUT (Steady)	5.6 A - maximum continuous output current rating per datasheet Table 10, validated up to T_J = 125 °C.
R_DS-ON	≤25 mΩ at T_J = 125 °C - ensures low conduction loss and thermal rise under full load in VFQFPN-48L package.
t_PD(H-L)	60–100 µs - propagation delay from IN high-to-low to OUT turn-off, critical for timing-critical PLC I/O cycles.
V_DEMAG	V_CC−72.5 V (min) - active clamp voltage enabling rapid inductive energy dissipation without external snubbers.
T_JSD/T_CSD	170 °C / 130 °C - independent junction and case thermal shutdown thresholds prevent latch-up and board-level overheating.
IPK_H/ILIM_H	25.1 A / 17.9 A (typ.) - initial peak-current threshold and limitation level for bulb lamp inrush management.

Pinout & Package

IPS1025HQ-32 is housed in a VFQFPN-48L package (8 mm × 6 mm × 0.9 mm), with exposed thermal pad for enhanced heat dissipation. Pin functions are validated per DS13780 Rev 7 Figure 2 and Table 1.

Pin/Terminal	Circuit Role	Design Meaning
IN	Logic input control	CMOS-compatible input (V_IH ≥ 2.2 V) enabling direct MCU GPIO drive; includes 0.4 V hysteresis for noise immunity.
OUT	Power stage output	High-side switched output (pins 17–24, 35–42 shorted on PCB); carries full load current with R_DS-ON ≤ 25 mΩ.
FLT1	Junction over-temperature diagnostic	Current-source fault pin (−4.0 mA sink @ V_FLT = 1 V) activated when T_J > 170 °C; requires 1.5 kΩ pull-down if unused.
FLT2	Overload event diagnostic	Current-source fault pin (−4.0 mA sink @ V_FLT = 1 V) activated when output current exceeds IPK threshold; blanking time 200–550 µs.
IPD	Overload threshold configuration	Configures protection mode: capacitor-to-GND enables dual-threshold; 10 kΩ-to-GND selects IPK_H; 220 kΩ-to-IN selects IPK_L.
VCC	Supply input	Primary power rail (8–60 V); includes clamp at 70.0 V (typ.) to suppress transients per IEC 61000-4-5.
GND	Reference ground	Device ground reference; GND disconnection detection triggers <0.5 mA leakage current on OUT pin.

Key Features

Feature	Design Value
Smart capacitive load driving	Configurable dual-threshold overload protection (IPK_H/ILIM_H + IPK_L/ILIM_L) via IPD pin capacitor, enabling controlled inrush for incandescent lamps.
Fast demagnetization	Active clamp circuit pulls OUT to V_CC−72.5 V during inductive turn-off, eliminating need for external flyback diodes or snubbers.
Dual thermal protection	Independent junction (170 °C shutdown) and case (130 °C shutdown) sensors prevent thermal runaway and enable safe restart after cooling.
IEC-compliant ESD/EMI robustness	Designed to meet IEC 61000-4-2 (ESD), -4-4 (EFT), and -4-5 (surge) standards-critical for factory-floor industrial environments.
Diagnostic current-source outputs	FLT1 and FLT2 provide galvanically isolated fault signaling (−4.0 mA sink) compatible with optocoupler inputs or MCU ADC monitoring.

Numerical Control (CNC) Axis I/O

Industrial PC Peripheral Interface

Use Scenario: Managing coolant pumps, tool changers, and limit switches in CNC machine tool cabinets with high EMI exposure.

IC Role / Device Role / Timing Role: ESD-hardened high-side driver with IEC 61000-4-2/4-4/4-5 compliance and fast demagnetization for inductive actuators.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
IPS1025H-32	Same VFQFPN-48L package and pinout, but rated for 2.4 A steady-state current and lower overload thresholds (IPK_H = 15.4 A, ILIM_H = 9.0 A).	Targeted at lower-power industrial I/O where thermal budget is constrained and peak loads are less demanding.	Select when load current remains ≤2.4 A and cost sensitivity outweighs need for 5.6 A headroom.
STSPIN32F0B	Integrated 3-phase gate driver + Cortex-M0 MCU; lacks dedicated high-side switch architecture and dual thermal sensing.	Designed for BLDC motor control-not suitable as drop-in replacement for discrete load switching.	Only consider for new designs requiring embedded motor control; not a functional substitute for IPS1025HQ-32's pure high-side switching role.

Compared with IPS1025H-32, the HQ-32 variant delivers 133% higher steady-state current and 64% higher peak overload tolerance, making it optimal for high-dynamic industrial loads; STSPIN32F0B introduces MCU integration but sacrifices diagnostic granularity and thermal independence required in safety-critical I/O modules.

FAQ

What is the maximum continuous output current for IPS1025HQ-32?

The IPS1025HQ-32 supports a maximum steady-state output current of 5.6 A, as specified in Table 10 of DS13780 Rev 7. This rating holds up to junction temperature T_J = 125 °C and assumes proper PCB thermal design using the VFQFPN-48L package's exposed pad. Derating applies above this temperature.

How does the IPD pin configure overload protection modes?

The IPD pin selects among three overload protection configurations: connecting to GND via a capacitor (470 pF–470 nF) enables dual-threshold mode (IPK_H/ILIM_H + IPK_L/ILIM_L); a 10 kΩ resistor to GND selects single-high mode (IPK_H only); a 220 kΩ resistor to IN selects single-low mode (IPK_L only). Floating IPD defaults to 1 µs IPK_H duration.

What thermal protections are implemented, and how do they interact?

IPS1025HQ-32 integrates two independent thermal protections: junction shutdown at 170 °C (reset at 150 °C) and case shutdown at 130 °C (reset at 110 °C). Junction protection activates first during overload; if case temperature then exceeds 130 °C, case protection overrides and holds output off until both temperatures fall below their reset thresholds.

Can FLT1 and FLT2 be used simultaneously with a single microcontroller input?

Yes-both FLT1 and FLT2 are open-drain current-source outputs (−4.0 mA sink) that can be wire-OR'd into a single MCU GPIO with a shared pull-up resistor. Their distinct fault conditions (FLT1 = junction/case over-temperature; FLT2 = overload) allow combined monitoring, though separate routing is recommended for precise root-cause diagnosis in safety-critical systems.
