Product details
Overview
IPS1025HTR from STMicroelectronics is a single-channel high-side switch IC designed for industrial load control, featuring 8–60 V supply operation, ≤25 mΩ RDS-ON at 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 (VDEMAG = VCC−72.5 V) and diagnostic FLT1/FLT2 pins for fault reporting.
For engineers reviewing the IPS1025HTR datasheet, IPS1025HTR pinout, IPS1025HTR application, or IPS1025HTR equivalent, key selection criteria include its 2.4 A continuous output rating (IPS1025H variant), PowerSSO-24 package thermal resistance (Rth(JC) = 0.7 °C/W), smart capacitive-load driving via IPD pin configuration, and IEC 61000-4-2/4-4/4-5 compliance for harsh industrial environments.
Technical Context
The IPS1025HTR implements a thermally robust high-side power stage with dual independent temperature monitoring: junction shutdown at 150–190 °C (TJSD) and case shutdown at 130 °C (TCSD), both with 20 °C hysteresis. Its overload protection supports three user-configurable modes-dual-threshold (via IPD-to-GND capacitor), single-low (IPD-to-IN resistor), or single-high (IPD-to-GND resistor)-enabling precise current limiting for lamp inrush (IPKH = 15.4 A) or steady-state loads (IPKL = 8.0 A).
It integrates active clamp circuitry for inductive load demagnetization (VDEMAG = VCC−72.5 V), under-voltage lockout (VUVON = 6.9 V, VUVOFF = 6.5 V), VCC overvoltage clamping (70.0 V typ), and ground disconnection detection (ILGND ≤ 0.5 mA). Diagnostic pins FLT1 and FLT2 are open-drain current sources (−4.0 mA fault sink) with 200–550 µs blanking time.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 8 V to 60 V - Enables direct connection to 12/24/48 V industrial bus rails without external regulation. |
| RDS-ON | ≤25 mΩ at TJ = 125 °C - Minimizes conduction loss and self-heating during 2.4 A continuous operation. |
| IOUT Continuous | 2.4 A - Maximum steady-state load current supported by IPS1025H variant (not -32 version). |
| Overload Thresholds | IPKH = 15.4 A / IPKL = 8.0 A - Dual thresholds allow safe lamp hot-switching and sustained motor/load operation. |
| Thermal Shutdown | TJSD = 150–190 °C, TCSD = 130 °C - Independent junction and case sensors prevent thermal runaway under overload or poor heatsinking. |
| Demagnetization Voltage | VDEMAG = VCC−72.5 V - Fast inductive energy dissipation reduces voltage spikes and EMI in solenoid/valve drivers. |
| Diagnostic Pins | FLT1 (over-temp), FLT2 (overload) - 4 mA current-source outputs enable direct LED or MCU GPIO fault indication without pull-up resistors. |
Pinout & Package
IPS1025HTR is packaged in PowerSSO-24, a thermally enhanced exposed-pad SOIC variant with 0.7 °C/W junction-to-case thermal resistance. The exposed pad must be soldered to PCB copper for thermal performance and electrical grounding.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| VCC (Pin 1, exposed pad) | Supply input | Main 8–60 V power rail connection; exposed pad is electrically tied to GND and critical for thermal conduction. |
| IN (Pin 23) | Logic input | CMOS-compatible control signal (VIH ≥ 2.2 V); hysteresis of 0.4 V prevents noise-induced switching. |
| OUT (Pins 5–20) | Power output | High-side switched output; all 16 pins must be shorted on PCB to handle 2.4 A with low inductance. |
| FLT1 (Pin 21) | Over-temperature flag | Current-source fault output activated when junction or case exceeds shutdown threshold; requires 1.5 kΩ pull-down if unused. |
| FLT2 (Pin 4) | Overload flag | Current-source fault output triggered by overcurrent events; blanking time (200–550 µs) suppresses false triggers during transients. |
| IPD (Pin 22) | Protection mode selector | Configures overload behavior: capacitor → dual threshold; 220 kΩ to IN → single low; 10 kΩ to GND → single high. |
| GND (Pin 24) | Reference ground | Signal reference for IN/FLT/ILIM circuits; separate from power ground path but connected internally to exposed pad. |
Key Features
| Feature | Design Value |
|---|---|
| Smart capacitive-load driving | Configurable IPKH/IPKL thresholds and DPK timing (215 × CPD) enable reliable hot-switching of incandescent lamps without false tripping. |
| Fast inductive demagnetization | VDEMAG = VCC−72.5 V actively clamps OUT during turn-off, reducing flyback voltage stress and enabling compact snubberless designs. |
| Dual thermal protection | Independent junction (TJSD) and case (TCSD) sensors ensure safe operation even with degraded heatsinking or localized hot spots. |
| Ground disconnection detection | Monitors GND integrity via ILGND ≤ 0.5 mA; forces output OFF during wiring faults to prevent uncontrolled load activation. |
| IEC-compliant EMC robustness | Designed to meet IEC 61000-4-2 (ESD ±8 kV contact), -4-4 (EFT 2 kV), and -4-5 (surge 1 kV line-earth) for industrial field deployment. |

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, identical electrical specs; differs only in reel/tube packaging and RoHS marking (HTR = tape-and-reel, H = tube). | No functional difference; HTR is preferred for automated SMT assembly, H for prototyping or low-volume hand-soldering. | Select IPS1025HTR for production lines requiring pick-and-place compatibility and full traceability. |
| IPS1035HTR | Higher RDS-ON (≤35 mΩ), lower IOUT (1.8 A), same package and feature set; lacks VFQFPN-48L option. | Suitable for lower-power loads where thermal margin is less constrained; shares identical pinout and diagnostic logic. | Choose IPS1035HTR only if 1.8 A rating suffices and cost reduction is prioritized over headroom. |
Compared with IPS1025HTR, IPS1025H offers identical performance in tube packaging for manual assembly, while IPS1035HTR trades 25% lower current capability for reduced conduction loss sensitivity-making it viable only in thermally relaxed, lower-power applications.

FAQ
What is the maximum continuous output current for IPS1025HTR?
The IPS1025HTR (IPS1025H variant) supports 2.4 A continuous output current at TJ ≤ 125 °C with proper PCB copper area and airflow. This rating assumes RDS-ON ≤ 25 mΩ and thermal resistance Rth(JC) = 0.7 °C/W in PowerSSO-24 package. Exceeding this current risks triggering junction over-temperature shutdown.
How does the IPD pin configure overload protection modes?
The IPD pin selects among three overload behaviors: connecting to GND via capacitor enables dual-threshold mode (IPKH = 15.4 A, IPKL = 8.0 A); connecting to IN via 220 kΩ resistor sets single low-threshold mode (IPKL only); connecting to GND via 10 kΩ resistor sets single high-threshold mode (IPKH only). Floating IPD defaults to 1 µs IPKH duration.
Can IPS1025HTR drive inductive loads without external flyback components?
Yes. Its integrated active clamp circuit provides fast demagnetization with VDEMAG = VCC−72.5 V, eliminating the need for external freewheeling diodes or RC snubbers in most 24 V industrial solenoid and relay applications. This reduces BOM count and improves EMI performance.
What is the purpose of the FLT1 and FLT2 diagnostic pins?
FLT1 is a current-source output activated during junction or case over-temperature events; FLT2 activates during overload conditions. Both sink up to 4 mA and require external pull-down resistors (1.5 kΩ recommended) if unused. They provide direct, hardware-level fault signaling to MCUs or status LEDs without software polling.
