Product details
Overview
VNQ05XSP16-E from STMicroelectronics is a quad-channel high-side solid-state relay IC designed for automotive and industrial load switching with ground-referenced loads. It delivers 5A continuous output current per channel, features CMOS-compatible inputs, multiplexed proportional current sense (K = 650–1200 A/A), integrated overvoltage clamp (41–55 V), and thermal shutdown at 150–200°C. It is used in body control modules for driving lamps, solenoids, and actuators in 12V/24V systems.
For engineers reviewing the VNQ05XSP16-E datasheet, VNQ05XSP16-E pinout, VNQ05XSP16-E application, or VNQ05XSP16-E equivalent, key selection criteria include per-channel RON (110 mΩ @ 25°C), ISO 7637-2 transient immunity (Class C across all pulses), reverse battery protection capability, multiplexed analog current sense accuracy (±10% drift over –40°C to +150°C), and PowerSO-16™ package thermal resistance (Rthj-case = 1.6°C/W).
Technical Context
The VNQ05XSP16-E integrates four independent VIPower M0-3 high-side switches with shared analog current sense mux and logic-selectable channel routing (SELA/SELB). Each channel implements active current limiting (5–10 A), thermal shutdown with hysteresis (THYST = 7–15°C), and loss-of-ground detection that forces automatic turn-off.
Its protection architecture includes correlated overvoltage shutdown (VOV = 36 V) and clamp (Vclamp = 41–55 V), undervoltage lockout (VUSD = 3–5.5 V), and reverse battery tolerance via external RGND/DGND networks. The device operates from 5.5 V to 36 V supply and supports 13.5 V battery transients up to 86.5 V (ISO 7637 Pulse 5).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 5.5 V to 36 V - Supports full automotive battery range including cold-crank (5.5 V) and load-dump (36 V DC max) |
| RON (per channel) | 110 mΩ @ Tj = 25°C - Enables <1 W conduction loss at 5 A, critical for thermally constrained PCB layouts |
| IOUT (cont.) | 5 A per channel - Sustains lamp, fan, and solenoid loads without external heatsinking under typical ambient conditions |
| Current Sense Ratio K | 650–1200 A/A - Delivers 0.83–1.54 mA sense current per amp of load, enabling accurate µC ADC monitoring with 3.9 kΩ resistor |
| Thermal Shutdown | 150–200°C - Protects against sustained overload while allowing safe transient overloads (e.g., motor stall) |
| ISO 7637-2 Immunity | Class C for Pulses 1–5 - Survives automotive electrical transients without latch-up or damage, eliminating need for external TVS on VCC |
| tDSENSE | 300–500 µs - Defines minimum sensing latency for closed-loop current monitoring and fault response timing |
Pinout & Package
Delivered in PowerSO-16™ package (14.1 mm × 9.5 mm × 3.6 mm), featuring exposed die-pad for enhanced thermal dissipation (Rthj-case = 1.6°C/W) and optimized copper layout compatibility per ST's recommended footprint (6 cm² Cu area).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pin 1) | Power ground reference | Common return for all channels; disconnecting triggers automatic shutdown |
| INPUT 4 (Pin 2) | Channel 4 digital enable input | CMOS-compatible (VIL = 1.25 V, VIH = 3.25 V); drives internal gate driver |
| C.SENSE (Pin 3) | Multiplexed analog current sense output | Delivers IOUTx/K voltage via external RSENSE; shared across multiple devices when SENSENABLE asserted |
| SENSENABLE (Pin 4) | Current sense bus enable | Active-high enables analog mux output; allows daisy-chaining of multiple VNQ05XSP16-E units on one sense line |
| N.C. (Pin 5) | No connect | Internally unused; must be left floating or tied to GND per layout guidelines |
| INPUT 1 (Pin 6) | Channel 1 digital enable input | Same logic thresholds as INPUT 4; independent control per channel |
| INPUT 2 (Pin 7) | Channel 2 digital enable input | Supports asynchronous channel activation; no inter-channel timing dependency |
| INPUT 3 (Pin 8) | Channel 3 digital enable input | Enables discrete control of third load without affecting other outputs |
| SELA (Pin 9) | Sense channel select A | Binary address bit (with SELB) to route IOUT1–4 to C.SENSE; defines which channel's current is reported |
| SELB (Pin 10) | Sense channel select B | Completes 2-bit mux address (00=CH1, 01=CH2, 10=CH3, 11=CH4) |
| VCC (Pins 11,12) | Main power supply | Dual-pin connection reduces IR drop and improves transient robustness; rated 41 V absolute max |
| N.C. (Pin 13) | No connect | Internally unused; no routing or bonding |
| OUTPUT 1 (Pin 14) | Channel 1 high-side switch output | Drives load between this pin and GND; supports inductive demag via internal clamp |
| OUTPUT 2 (Pin 15) | Channel 2 high-side switch output | Independent output path; shares thermal shutdown but not current limit circuitry |
| OUTPUT 3 (Pin 16) | Channel 3 high-side switch output | Same RON, protection, and timing specs as OUTPUT 1/2 |
| OUTPUT 4 (Pin 17) | Channel 4 high-side switch output | Final channel output; fully identical in spec and function to others |
Key Features
| Feature | Design Value |
|---|---|
| Quad independent high-side switches | Four isolated 5 A channels with individual enable pins-enables modular load control without cross-talk or shared failure modes |
| Multiplexed proportional current sense | Single C.SENSE pin reports selected channel's load current with ±10% ratio drift over full temperature range-reduces µC ADC channel count and PCB routing complexity |
| Loss-of-ground detection | Automatic channel disable upon GND pin disconnection-prevents uncontrolled load operation and protects downstream circuits during wiring faults |
| Integrated overvoltage clamp & shutdown | Vclamp = 41–55 V and VOV = 36 V act in concert to suppress transients and halt switching before destructive energy accumulates |
| Reverse battery protection support | Compatible with external DGND diode or RGND resistor networks-enables robust operation in vehicles with reversed jumper cable connections |
| ISO 7637-2 Class C immunity | Passes all five test pulses (including 86.5 V Pulse 5) without functional interruption-eliminates need for external VCC TVS in most automotive designs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad high-side switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS4H160-Q1 | Lower RON (70 mΩ), integrated diagnostics (open-load, short-to-VCC), but no multiplexed analog sense output | Preferred where advanced diagnostics and lower conduction loss outweigh need for analog current feedback | Select when system uses CAN-based diagnostics and does not require µC ADC monitoring of individual channel currents |
| IPS1032H | Higher current rating (10 A), same PowerSO-16™ package, but lacks SELA/SELB mux and has fixed single-channel sense | Better suited for high-power single-load applications rather than multi-channel proportional monitoring | Choose when driving one large load (e.g., radiator fan) instead of four independent medium-current loads |
Compared with TPS4H160-Q1 and IPS1032H, the VNQ05XSP16-E uniquely balances quad-channel integration, multiplexed analog current sense, and automotive-grade transient robustness-making it optimal for cost-sensitive, space-constrained BCMs requiring per-channel diagnostics without added ICs.

FAQ
What is the maximum continuous output current per channel?
The VNQ05XSP16-E supports 5 A continuous output current per channel at Tc ≤ 25°C with adequate PCB copper area (≥6 cm²). Derating applies above 25°C case temperature-e.g., ~3.5 A at Tc = 100°C per the Rthj-amb = 51.6°C/W thermal data. Current limit is internally set at 5–10 A depending on VCC and junction temperature.
How does the multiplexed current sense work?
The C.SENSE pin outputs a current ISENSE = IOUTx/K, where K varies from 650 to 1200 A/A depending on load and temperature. SELA and SELB pins select which of the four channels feeds the sense output; SENSENABLE enables the mux. An external resistor (e.g., 3.9 kΩ) converts ISENSE to a voltage readable by a microcontroller ADC.
Can VNQ05XSP16-E withstand reverse battery conditions?
The VNQ05XSP16-E itself does not tolerate reverse battery directly, but ST provides two validated external protection methods: (1) a series resistor (RGND ≤ 600 mV/IS(on)max) in the ground path, or (2) a small-signal diode (DGND) with parallel 1 kΩ resistor for inductive loads. Both methods are detailed in the application schematic (page 9 of datasheet).
What is the turn-on/turn-off delay time?
Measured with RL = 2.6 Ω resistive load, the VNQ05XSP16-E exhibits td(on) = 40 µs and td(off) = 40 µs. These values remain stable across –40°C to +150°C junction temperature. The current sense delay tDSENSE is 300–500 µs, reflecting the time from input edge to valid analog sense output.
