Product details
Overview
IPS2050HQ from STMicroelectronics is a dual-channel high-side switch IC designed for industrial load control, featuring 8–60 V supply range, ≤50 mΩ RDS-ON at 125 °C, and 2.4 A steady-state output current per channel. It integrates per-channel overload/over-temperature diagnostics via dedicated FAULT pins and supports smart capacitive-load driving with dual-threshold current limiting (IPKH-X/IPKL-X) for lamp inrush management in PLC I/O modules.
For engineers reviewing the IPS2050HQ datasheet, IPS2050HQ pinout, IPS2050HQ application, or IPS2050HQ equivalent, key selection criteria include its dual-threshold overload protection architecture, case/junction temperature monitoring hierarchy, PowerSSO-24 thermal resistance (Rth(JC) = 0.7 °C/W), and diagnostic pin sourcing capability (–4 mA at VFLT = 1 V).
Technical Context
The device implements independent per-channel current sensing with programmable dual-threshold activation (IPKH-X up to 11.5 A, IPKL-X at 5.2 A) and time-limited initial limitation (DPKX = 215 × CPD µs). Each channel features junction temperature shutdown at 150–190 °C and case temperature shutdown at 130 °C, with reset hysteresis of 7–20 °C and 20 °C respectively.
Its active clamp circuit enables fast demagnetization of inductive loads with VDEMAG = VCC – 72.5 V (typ.), while under-voltage lockout (VUVON = 6.9 V, VUVOFF = 6.5 V) and VCC overvoltage clamping (70.0 V typ.) ensure robust supply rail handling across industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 8 V to 60 V - Enables direct connection to 12/24/48 V industrial power rails without external regulation. |
| Max Steady-State Output Current | 2.4 A per channel - Sustains continuous load drive for solenoids, valves, and LED banks in PLC outputs. |
| RDS-ON (TJ = 125 °C) | ≤ 50 mΩ - Minimizes conduction loss (< 290 mW at 2.4 A), reducing thermal stress in compact enclosures. |
| Fault Pin Drive Strength | –4 mA at VFLT = 1 V - Provides reliable open-collector-compatible diagnostic signaling to microcontrollers without external pull-downs. |
| Thermal Shutdown Threshold | Junction: 150–190 °C; Case: 130 °C - Enables layered thermal protection: channel-level shutdown precedes system-level shutdown for graceful fault containment. |
| Demagnetization Voltage | VCC – 72.5 V (typ.) - Limits inductive kickback to safe levels during turn-off, eliminating need for external flyback diodes in relay drivers. |
| Propagation Delay (L→H) | 14–25 µs - Ensures deterministic timing for real-time I/O control loops in motion control systems. |
Pinout & Package
IPS2050HQ is available in PowerSSO-24 package: 10.3 mm × 7.5 mm body, 0.7 mm height, exposed thermal pad for enhanced heat dissipation. Thermal resistance junction-to-case is 0.7 °C/W per channel, enabling high-power operation without heatsinks in forced-air environments.
| Pin / Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1 / IN2 | Digital input control | CMOS-compatible logic inputs (VIH ≥ 2.2 V) enabling direct MCU GPIO interfacing; internal hysteresis (0.4 V) prevents noise-induced switching. |
| OUT1 / OUT2 | High-side power output | Parallel-pin configuration (pins 5–12 and 13–20 for OUT2/OUT1) reduces trace inductance and increases current-carrying capacity for 2.4 A loads. |
| FLT1 / FLT2 | Fault diagnostic output | Active-low current-source pins (–4 mA typical) that assert during overload or over-temperature events on respective channels; require 1.5 kΩ pull-down if unused. |
| IPD1 / IPD2 | Overcurrent threshold selector | Analog-configurable pins: capacitor-to-GND sets dual-threshold timing; 220 kΩ to IN disables IPKH; 10 kΩ to GND disables IPKL - enabling field-programmable protection profiles. |
| VCC | Power supply input | Accepts 8–60 V with integrated 70 V clamp; internal UVLO ensures clean startup/shutdown sequencing across wide-input industrial supplies. |
| GND | Reference ground | Multi-pin grounding (24 pins total) minimizes ground bounce and improves EMI immunity in noisy factory environments. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-threshold overload protection | Configurable IPKH-X (11.5 A) and IPKL-X (5.2 A) thresholds with programmable DPKX timing enable optimized inrush handling for incandescent lamps and motor startups. |
| Independent junction/case thermal monitoring | Separate TJSD (150–190 °C) and TCSD (130 °C) thresholds allow channel-level fault recovery without full system reset, improving system uptime in multi-load applications. |
| Active clamp demagnetization | VDEMAG = VCC – 72.5 V limits inductive voltage spikes during turn-off, eliminating external snubbers in relay and solenoid driver designs. |
| Ground disconnection detection | Monitors ILGND leakage current (≤0.5 mA) to detect broken ground connections, forcing channel shutdown before unsafe floating-voltage conditions arise. |
| IEC 61000-4-2/4/5 compliance | Integrated ESD (±8 kV contact), EFT (±2 kV), and surge (±1 kV line-earth) protection reduce external TVS component count in industrial I/O modules. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VNS3NV04PTR-E | Single-channel, 4 A rated, no dual-threshold overload or case temperature sensing; RDS-ON = 40 mΩ at 25 °C but uncharacterized above 100 °C. | Lacks per-channel diagnostics and thermal layering; suitable only for non-critical, single-load applications without fault reporting requirements. | Select when cost sensitivity outweighs diagnostic needs and thermal margin is sufficient for single-load use cases. |
| TPS27082LDR | Single-channel, 2.5 A rated, integrated charge pump for 3.3/5 V logic compatibility; no active clamp or IEC-compliant ESD/EFT protection. | Requires level-shifting for industrial 24 V control signals; lacks built-in demagnetization, necessitating external flyback components for inductive loads. | Choose for low-voltage embedded systems where logic-level compatibility and small footprint outweigh industrial ruggedness needs. |
Compared with VNS3NV04PTR-E and TPS27082LDR, IPS2050HQ provides dual-channel integration, layered thermal protection (junction + case), and field-programmable overload thresholds-enabling higher system reliability and reduced BOM count in industrial PLC and NC machine I/O designs.

FAQ
What is the maximum continuous output current per channel for IPS2050HQ?
The IPS2050HQ supports 2.4 A steady-state output current per channel at junction temperatures up to 125 °C, with RDS-ON guaranteed ≤50 mΩ. This rating assumes proper PCB copper pour and thermal management per the PowerSSO-24 layout guidelines in DS13779 Section 9.1.
How does the dual-threshold overload protection work on IPS2050HQ?
When IPDx is connected to GND via a capacitor (470 pF–470 nF), IPS2050HQ activates IPKH-X (11.5 A) for an initial duration DPKX = 215 × CPD µs after INx goes high, then switches to IPKL-X (5.2 A) for sustained overload protection. This accommodates lamp inrush while preventing thermal runaway during faults.
Can IPS2050HQ drive inductive loads without external components?
Yes - its integrated active clamp circuit provides fast demagnetization with VDEMAG = VCC – 72.5 V (typ.), eliminating the need for external flyback diodes or RC snubbers when driving relays, solenoids, or DC motors in industrial applications.
What thermal protection layers does IPS2050HQ implement?
IPS2050HQ implements two independent thermal protections: junction temperature shutdown (TJSD = 150–190 °C) per channel and case temperature shutdown (TCSD = 130 °C). The case sensor triggers only after junction protection has cycled repeatedly, ensuring fault containment without premature system-wide shutdown.
