Product details

Overview

IPS2050HQ-32 from STMicroelectronics is a dual-channel high-side switch IC designed for industrial load driving with smart capacitive-load handling and extended diagnostics. It operates from 8 V to 60 V, delivers up to 5.6 A per channel (steady-state), features ≤50 mΩ R_DS(on) at T_J = 125 °C, and integrates per-channel overload/over-temperature fault reporting via dedicated current-source FLT pins. It is used in programmable logic controllers to safely drive solenoids and relay coils under harsh EMI conditions.

For engineers reviewing the IPS2050HQ-32 datasheet, IPS2050HQ-32 pinout, IPS2050HQ-32 application, or IPS2050HQ-32 equivalent, key selection criteria include dual-threshold overcurrent protection (IPKH-X/IPKL-X), active demagnetization voltage (V_DEMAG = V_CC−72.5 V), case temperature shutdown (T_CSD = 130 °C), and PowerSSO-24 package thermal resistance (R_th(JC) = 0.7 °C/W).

Technical Context

The IPS2050HQ-32 implements two independent high-side power switches with embedded junction and case temperature sensing, enabling hierarchical thermal protection: channel-level shutdown at T_JSD = 150–190 °C and system-level shutdown at T_CSD = 130 °C. Each channel supports configurable overload response via IPD pin biasing-capacitor-coupled for dual-threshold timing (DPKX = 215 × C_PD), resistor-biased for single-level thresholds (IPKL-X = 10.5 A or IPKH-X = 19.8 A).

Its active clamp circuit provides fast demagnetization of inductive loads by pulling OUTX to V_CC−V_DEMAG (V_DEMAG = 72.5 V typ.), limiting voltage stress during turn-off. Fault signaling uses open-drain current-source FLT pins (I_HFLT = −3 mA typ. at V_FLT = 1 V) with 60–400 µs blanking time to reject noise-induced false triggers.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	8 V to 60 V - Enables direct connection to 24 V/48 V industrial rails without external regulation.
Max Output Current (per channel)	5.6 A steady-state - Supports high-power solenoids and motor starters without external heatsinking at moderate ambient.
R_DS(on) (max, T_J = 125 °C)	50 mΩ - Limits conduction loss to ≤1.57 W at 5.6 A, reducing thermal burden in compact enclosures.
Overcurrent Thresholds	IPKH-X = 19.8 A / IPKL-X = 10.5 A - Dual thresholds allow inrush current tolerance for lamps while maintaining safe steady-state limits.
Demagnetization Voltage	V_DEMAG = V_CC−72.5 V (typ.) - Clamps inductive kickback below −48.5 V at 24 V supply, protecting MOSFETs and PCB traces.
Fault Pin Output	Current-source FLT (−3 mA typ. at 1 V) - Drives LED indicators or microcontroller inputs directly without pull-up resistors.
Thermal Shutdown Thresholds	T_JSD = 150–190 °C; T_CSD = 130 °C - Case-based shutdown prevents board-level thermal runaway before junction damage occurs.

Pinout & Package

IPS2050HQ-32 is housed in a PowerSSO-24 package with exposed thermal pad for low R_th(JC) = 0.7 °C/W. The 24-pin layout includes dual-channel input (IN1/IN2), fault reporting (FLT1/FLT2), current-threshold configuration (IPD1/IPD2), dual output banks (OUT1: pins 13–20; OUT2: pins 5–12), supply (VCC: pin 1), ground (GND: pin 24), and NC pins (pins 25–34).

Pin/Terminal	Circuit Role	Design Meaning
VCC (pin 1)	Power supply input	Accepts 8–60 V; internal clamp activates at 70 V to prevent damage during transients.
IN1 / IN2 (pins 23 / 2)	Digital control inputs	CMOS-compatible (VIH ≥ 2.2 V); hysteresis of 0.4 V rejects noise on long PCB traces.
OUT1 / OUT2 (pins 13–20 / 5–12)	High-side power outputs	Parallel pins per channel reduce trace resistance and improve current sharing; must be shorted on PCB.
FLT1 / FLT2 (pins 21 / 4)	Fault diagnostic outputs	Active-low current-source pins (−3 mA) report overload/over-temperature; require 1.5 kΩ pull-down if unused.
IPD1 / IPD2 (pins 22 / 3)	Overcurrent threshold selector	Configures dual/single threshold mode via capacitor (470 pF–470 nF) or resistor (10 kΩ/220 kΩ) to GND or IN.
GND (pin 24)	Reference ground	Ground disconnection detection triggers immediate channel disable and ILGND ≤ 0.5 mA leakage.

Key Features

Feature	Design Value
Smart dual-threshold overload protection	Enables lamp preheat (19.8 A peak) and sustained coil hold (10.5 A), eliminating need for external NTC or timing circuits.
Integrated active clamp demagnetization	Replaces external freewheeling diodes and snubbers, reducing BOM count and PCB area in relay/solenoid drivers.
Independent junction + case thermal monitoring	Prevents localized hot spots (via TJ sensor) and board-level overheating (via TC sensor), supporting IEC 61000-4-5 surge survivability.
IEC-compliant ESD/EMI robustness	Meets IEC 61000-4-2 (±8 kV contact), -4-4 (±2 kV EFT), and -4-5 (±2 kV surge) without external protection components.
Ground disconnection detection	Shuts down outputs within microseconds if GND is lost, preventing uncontrolled load energization in safety-critical systems.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
IPS2050H-32	Same pinout and package; lower R_DS(on) (≤30 mΩ @ 25 °C) but identical 5.6 A rating and protection features.	Preferred where lower conduction loss is critical at room temperature; less tolerant of sustained high-T_J due to tighter thermal margins.	Select IPS2050H-32 for thermally constrained enclosures with forced airflow; IPS2050HQ-32 for passive-cooled or high-ambient deployments.
TPS27082L	Single-channel, 8.5 A rated, 20 V max supply; lacks case temperature sensing, dual-threshold overload, and active clamp.	Suitable only for low-voltage, non-inductive loads; requires external TVS and thermal monitoring for industrial use.	Choose only for cost-sensitive 12 V applications without inductive loads or safety certification requirements.

Compared with IPS2050H-32, the HQ-32 variant trades marginal R_DS(on) increase for enhanced thermal robustness at high junction temperatures; versus TPS27082L, it delivers full industrial-grade protection (IEC 61000-4-x, dual thermal sensing, active clamp) in a dual-channel form factor, reducing component count by 50% in multi-load systems.

FAQ

What is the maximum continuous output current per channel for IPS2050HQ-32?

The IPS2050HQ-32 supports 5.6 A continuous output current per channel under specified thermal conditions (T_C ≤ 150 °C, R_th(JC) = 0.7 °C/W). This rating assumes proper PCB copper pour and thermal vias under the exposed pad. At T_J = 125 °C, R_DS(on) remains ≤50 mΩ, limiting power dissipation to 1.57 W per channel.

How does the IPD pin configure overload protection behavior?

The IPD pin selects between dual-threshold (capacitor to GND), single-low-threshold (220 kΩ to IN), or single-high-threshold (10 kΩ to GND) modes. In dual mode, IPKH-X = 19.8 A activates for DPKX = 215 × C_PD µs after IN transition, then reverts to IPKL-X = 10.5 A. Leaving IPD floating defaults to 1 µs DPKX.

Can IPS2050HQ-32 drive inductive loads without external components?

Yes - its integrated active clamp circuit provides fast demagnetization by pulling OUTX to V_CC−72.5 V, eliminating the need for external freewheeling diodes or RC snubbers. This reduces component count and PCB area while ensuring controlled energy dissipation during inductive turn-off.

What fault conditions activate the FLT pins, and how are they electrically implemented?

FLT1/FLT2 activate as current sources (−3 mA typ. at 1 V) during per-channel overload, junction overtemperature (T_J > 150 °C), or case overtemperature (T_C > 130 °C). They are not open-drain but actively sink current, allowing direct LED drive or microcontroller input assertion without pull-up resistors. Blanking time is 60–400 µs to suppress noise.
