Product details
Overview
IPS1025HQ from STMicroelectronics is a single-channel high-side switch IC designed for industrial load control, featuring 8 V to 60 V supply operation, ≤25 mΩ RDS(on) at TJ = 125 °C, dual-threshold overload protection (IPKH/IPKL), and integrated junction + case over-temperature shutdown. It drives resistive, capacitive (e.g., incandescent lamps), and inductive loads with fast demagnetization and ground disconnection protection.
For engineers reviewing the IPS1025HQ datasheet, IPS1025HQ pinout, IPS1025HQ application, or IPS1025HQ equivalent, this device supports robust diagnostics via FLT1/FLT2 current-source fault pins, configurable IPD-based current-limiting modes, and compliance with IEC 61000-4-2/4/5 EMC standards in PowerSSO-24 and VFQFPN-48L packages.
Technical Context
The IPS1025HQ implements dual-threshold current limiting: an initial high threshold (IPKH = 15.4 A) active for DPK = 215 × CPD µs (470 pF–470 nF), followed by steady-state limiting at IPKL = 8.0 A with ILIML = 3.5 A typical. Its active clamp circuit enables fast demagnetization of inductive loads by pulling OUT to VCC−VDEMAG (VCC−72.5 V typical).
Thermal protection uses two independent sensors: junction shutdown triggers at TJSD = 170 °C with 20 °C hysteresis, while case shutdown activates at TCSD = 130 °C. Fault reporting is implemented via two dedicated current-source diagnostic pins-FLT1 for thermal events and FLT2 for overload-with blanking time of 200–470 µs and clamp voltage of 6.8 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RDS(on) | ≤25 mΩ at TJ = 125 °C - enables 2.4 A continuous output with low conduction loss and minimal self-heating |
| VCC Range | 8 V to 60 V - supports wide industrial supply rails including 24 V and 48 V systems without external regulation |
| IPKH / IPKL | 15.4 A / 8.0 A - dual activation thresholds allow safe inrush handling for bulbs while maintaining stable steady-state current limiting |
| VDEMAG | VCC−72.5 V typical - fast active clamp dissipates inductive energy without external flyback diodes |
| TJSD / TCSD | 170 °C / 130 °C - independent junction and case thermal shutdown prevents latch-up and ensures system-level thermal safety |
| FLT Pin Type | Current-source (−4.0 mA fault sink) - directly interfaces with microcontroller GPIOs without pull-up resistors |
| UVLO Thresholds | VUVON = 6.9 V, VUVOFF = 6.5 V - tight hysteresis (0.4 V) prevents oscillation during brown-out conditions |
Pinout & Package
IPS1025HQ is available in two thermally optimized packages: PowerSSO-24 (exposed pad, Rth(JC) = 0.7 °C/W) and VFQFPN-48L (8×6×0.9 mm, Rth(JC) = 1.0 °C/W). Both support high-power dissipation and PCB-level thermal management via exposed thermal pads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Supply input | Accepts 8–60 V; includes internal clamp (70.0 V typical) and UVLO circuitry |
| OUT | Power stage output | High-side switched output; multiple pins (PSSO24: 5–20; VFQFPN: 17–24 & 35–42) must be shorted on PCB |
| IN | Digital input control | CMOS-compatible (VIH ≥ 2.2 V); 0.4 V hysteresis prevents noise-induced switching |
| GND | Reference ground | Device return path; GND disconnection detection triggers automatic channel disable |
| FLT1 | Thermal fault indicator | Current-source output activated during junction or case over-temperature events |
| FLT2 | Overload fault indicator | Current-source output activated when output current exceeds IPK thresholds |
| IPD | Protection mode selector | Configures dual/single threshold mode via capacitor (CPD) or resistor (10 kΩ/220 kΩ) to IN/GND |
Key Features
| Feature | Design Value |
|---|---|
| Smart capacitive load driving | Configurable IPKH/IPKL thresholds with programmable DPK timing enable safe lamp pre-heat and hold without external timers |
| Fast inductive demagnetization | VDEMAG = VCC−72.5 V clamping reduces decay time and eliminates need for external snubbers or freewheeling diodes |
| Dual thermal protection | Independent junction (TJSD = 170 °C) and case (TCSD = 130 °C) sensors prevent thermal runaway under sustained overload |
| Ground disconnection detection | ILGND ≤ 0.5 mA leakage during GND loss ensures fail-safe shutdown without external monitoring circuitry |
| IEC-compliant EMC robustness | Designed to meet IEC 61000-4-2 (ESD ±8 kV contact), -4-4 (EFT 4 kV), and -4-5 (surge 2 kV line-earth) |

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 | Same die, PowerSSO-24 only; no VFQFPN-48L option; identical electrical specs except Rth(JC) = 0.7 °C/W fixed | Limited to lower-power thermal profiles due to absence of VFQFPN-48L's superior heat spreading | Select when board layout constraints favor PowerSSO-24 and peak power dissipation remains below 3.5 W |
| IPS2050H | Higher RDS(on) (≤40 mΩ), single-threshold overload (IPK = 10 A), no case temperature sensing, no IPD pin | Lacks smart capacitive load handling and dual thermal protection; simpler configuration but reduced diagnostic granularity | Choose for cost-sensitive designs where dual-threshold control and case-level thermal monitoring are not required |
Compared with IPS1025H, IPS1025HQ adds VFQFPN-48L packaging for higher thermal performance; versus IPS2050H, it delivers enhanced diagnostics, dual thermal sensing, and programmable inrush management-critical for mission-critical industrial loads.

FAQ
What is the maximum continuous output current rating for IPS1025HQ?
The IPS1025HQ supports up to 2.4 A continuous output current at TJ ≤ 125 °C, enabled by its low RDS(on) of ≤25 mΩ. This rating assumes proper PCB copper area, thermal vias, and ambient conditions per the VFQFPN-48L or PowerSSO-24 thermal data (Rth(JC) = 1.0 °C/W or 0.7 °C/W respectively). Derating applies above 85 °C ambient.
How does the IPD pin configure overload protection modes?
The IPD pin selects between three overload configurations: connecting to GND via a capacitor (470 pF–470 nF) enables dual-threshold mode (IPKH/ILIMH then IPKL/ILIML); a 220 kΩ resistor to IN forces single low-threshold mode (IPKL only); a 10 kΩ resistor to GND enables single high-threshold mode (IPKH only). Floating IPD defaults to 1 µs IPKH duration.
Can IPS1025HQ drive inductive loads without external components?
Yes-IPS1025HQ integrates active clamp circuitry that pulls OUT to VCC−VDEMAG (VCC−72.5 V typical) during turn-off, enabling fast demagnetization of inductive loads without external flyback diodes or snubbers. This reduces BOM cost and improves reliability in motor and solenoid applications.
What fault conditions activate FLT1 versus FLT2?
FLT1 activates exclusively for thermal faults: junction over-temperature (TJ > 170 °C) or case over-temperature (TC > 130 °C). FLT2 activates only for overload events-when output current exceeds IPKH or IPKL thresholds. Both pins operate as current sources (−4.0 mA typical sink) and require no external pull-up resistors.
