Product details
Overview
IPS8160HQ-1 from STMicroelectronics is an octal high-side driver IC built on VIPower M0-3 technology, designed to switch DC-13 loads per EN 60947-5-1 with up to 1.0 A steady-state output current per channel, CMOS-compatible 3.3 V logic inputs, and integrated thermal/overload protection. It operates from 11.5–32 V supply and supports industrial PLC I/O, vending machine control, and CNC peripheral driving.
For engineers reviewing the IPS8160HQ-1 datasheet, IPS8160HQ-1 pinout, IPS8160HQ-1 application, or IPS8160HQ-1 equivalent, this device delivers verified channel-level current limiting (1.7 A short-circuit clamp), case-overtemperature shutdown (130 °C TCSD), active demagnetization (VDEMAG = VCC−52 V), STATUS diagnostic signaling, and UL 2367 certification - all in a QFN48L 8×6 mm package.
Technical Context
The IPS8160HQ-1 integrates eight independent high-side power switches with per-channel current sensing, junction and case thermal monitoring, and reverse-ground-loss detection. Each channel features active current limitation (ILIM = 1.7 A) and fast active clamp (dVOUT/dt(OFF) = 1.5 V/µs) for inductive load demagnetization.
Its protection architecture implements dual-threshold thermal shutdown: junction overtemperature (TJSD = 175 °C) triggers automatic restart cycling, while case overtemperature (TCSD = 130 °C) forces latched OFF until TCR = 110 °C. The open-source STATUS pin asserts high during any channel fault, enabling centralized diagnostics.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | 1.0 A continuous per channel; enables direct drive of solenoids, valves, and relay coils without external buffering. |
| ON-State Resistance | 160 mΩ max @ TJ = 25 °C; limits conduction loss to ≤160 mW at 1 A, reducing thermal stress in compact layouts. |
| Supply Voltage Range | 11.5–32 V DC; compatible with standard 24 V industrial bus rails and tolerant of brownout conditions down to 10.5 V VUSD. |
| Thermal Shutdown Threshold | Case temperature shutdown at 130 °C (TCSD); ensures channel independence by preventing thermal crosstalk between adjacent outputs. |
| Active Clamp Voltage | VDEMAG = VCC−52 V; clamps inductive kickback to safe levels, eliminating need for external flyback diodes in DC-13 load switching. |
| Status Pin Function | Open-source diagnostic output; sinks ≥3 mA during fault, allowing direct connection to microcontroller GPIO with pull-up for real-time channel health monitoring. |
| ESD Robustness | 2000 V HBM; meets IEC 61000-4-2 Level 4 requirements for industrial environments with frequent human interaction. |
Pinout & Package
Package: QFN48L 8×6×0.9 mm with exposed thermal pad (EP = VCC). RoHS-compliant ECOPACK® packaging with wettable flanks for automated optical inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2 / 35–48 | OUT1–OUT8 (dual-pin per channel) | Power output terminals; each pair must be shorted on PCB to handle 1 A per channel with low-inductance routing. |
| 14–21 | IN1–IN8 | CMOS-compatible digital inputs; accept 3.3 V logic with 0.25 V hysteresis to reject noise in electrically noisy factory floors. |
| 33 | GND | Output power ground reference; disconnecting this pin triggers immediate channel shutdown to prevent floating-load hazards. |
| 34 | STATUS | Common open-source fault indicator; asserts high during junction/case overtemperature, undervoltage, or overload on any channel. |
| EP | VCC | Power supply input and thermal interface; requires full-solder coverage of exposed pad for Rth(JC) = 1.5 °C/W per channel cooling. |
Key Features
| Feature | Design Value |
|---|---|
| Per-channel thermal independence | Separate TJSD and TCSD thresholds enable non-faulty channels to remain operational during localized overheating events. |
| Loss-of-ground detection | Automatic shutdown when GND pin disconnects - prevents uncontrolled load energization and meets SIL-2 functional safety prerequisites. |
| UL 2367 certification | Validated for use in industrial control equipment requiring recognized component safety compliance under 11.5–32 V operation. |
| DC-13 load compliance | Designed and tested per EN 60947-5-1 for reliable switching of inductive loads with time-constant up to 100 ms (e.g., contactors, solenoids). |
| Input ESD protection | Integrated 6.8 V input clamp with ±1 mA current handling eliminates need for external TVS diodes on INx lines. |
Applications
| Programmable Logic Controller I/O | Vending Machine Actuation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VNQ7E160AJTR | Single-channel 1.6 A high-side driver; no STATUS pin; RON = 130 mΩ; lacks case overtemperature protection. | Requires 8× discrete units for same channel count; no centralized fault reporting; higher board area and assembly cost. | Select only when single-channel modularity or lower RON is prioritized over integration and diagnostics. |
| TPS27082LDR | Octal 0.8 A high-side switch; no active clamp; STATUS pin is open-drain; RON = 200 mΩ; no UL certification. | Lacks EN 60947-5-1 DC-13 compliance and UL 2367 recognition; unsuitable for safety-critical industrial actuators. | Consider only for non-certified lab equipment or consumer-grade automation where regulatory approval is not required. |
Compared with VNQ7E160AJTR and TPS27082LDR, the IPS8160HQ-1 uniquely combines octal integration, UL 2367 certification, dual thermal shutdown (junction + case), and active clamp in one QFN48L package - making it the only drop-in solution for certified industrial PLC output modules requiring <100 ms response and <1 A per channel.

FAQ
What is the maximum capacitive load the IPS8160HQ-1 can safely drive?
The IPS8160HQ-1 supports up to 2.2 mF maximum capacitive load per channel when operated at VCC = 24 V and TAMB = 125 °C, as validated on ST's X-Nucleo-OUT19A1 evaluation board. This rating assumes other channels are open-load and accounts for internal charge pump limitations during rapid voltage transitions.
How does the STATUS pin behave during simultaneous junction and case overtemperature faults?
When both TJSD and TCSD are triggered, the STATUS pin remains asserted high continuously - it does not pulse or toggle. The pin deasserts only after all faulty channels cool below their respective reset thresholds (TJR = 135 °C and TCR = 110 °C), ensuring unambiguous fault persistence detection by the host controller.
Can the IPS8160HQ-1 drive loads with supply voltages above 32 V?
No - absolute maximum VCC is 45 V, but functional operation is guaranteed only within 11.5–32 V per UL 2367 certification and EN 60947-5-1 compliance. Operation above 32 V risks violating thermal derating curves and invalidates safety certification; sustained operation above 45 V causes permanent damage.
Is the QFN48L package lead-free and RoHS-compliant?
Yes - the IPS8160HQ-1 uses ST's ECOPACK®-qualified QFN48L package, fully compliant with RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. The package features matte tin plating and meets JEDEC J-STD-020 moisture sensitivity level 3 (MSL3) for standard SMT assembly.
