Product details
Overview
VNQ05XSP16 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 5 A continuous output current per channel, features CMOS-compatible inputs, multiplexed proportional current sense (K = 800–1200 A/A), integrated overvoltage clamp (41–55 V), and thermal shutdown at 150 °C. It is used in body control modules to drive lamps, solenoids, and actuators with real-time fault monitoring.
For engineers reviewing the VNQ05XSP16 datasheet, VNQ05XSP16 pinout, VNQ05XSP16 application, or VNQ05XSP16 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 architecture, and PowerSO-16™ thermal performance (Rthj-case = 1.6 °C/W).
Technical Context
The VNQ05XSP16 integrates four independent VIPower M0-3 high-side switches with shared analog current sense mux and digital logic for channel selection (SELA/SELB) and sensing enable (SENSENABLE). Each channel includes active current limiting (5–10 A), thermal shutdown with hysteresis (15 °C), and under/overvoltage protection (VUSD = 4 V typ., VOV = 36 V).
Its protection architecture responds to loss of ground, reverse battery (via external RGND/DGND network), and inductive demagnetization events, with clamped turn-off voltage (Vdemag = VCC − 48 V) and fast fault reporting via sense line voltage shifts (e.g., VSENSEH = 5.5 V during overtemperature).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output current (per channel) | 5 A continuous - supports automotive lamps, fuel pumps, and HVAC actuators without external heatsinking at moderate ambient. |
| RON (25 °C) | 110 mΩ - limits conduction loss to ≤2.75 W at 5 A, enabling efficient thermal management in PowerSO-16™ package. |
| VCC operating range | 5.5–36 V - compatible with 12 V and 24 V vehicle electrical systems including cold-crank (5.5 V) and load-dump (36 V) conditions. |
| Current sense ratio (K) | 800–1200 A/A - enables accurate 1–2 A sense current scaling for microcontroller ADC input with <±8% drift over −40 to +150 °C. |
| Thermal shutdown threshold | 150 °C - triggers automatic channel disable and outputs VSENSEH = 5.5 V to signal fault condition on shared sense line. |
| ISO 7637-2 immunity | Class C for all pulses (P1–P5) - survives automotive transients including −100 V/2 ms (pulse 1) and +86.5 V/400 ms (pulse 5) without latch-up or damage. |
| Standby supply current | 80 µA - minimizes quiescent drain in always-on vehicle modules such as gateway ECUs or alarm controllers. |
Pinout & Package
Package: PowerSO-16™ - thermally enhanced exposed-pad surface-mount package with Rthj-case = 1.6 °C/W, optimized for high-power automotive PCB layouts using ≥0.5 cm² copper pour.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pin 1) | Power ground reference | Primary return path for all channel currents and internal protection circuits; disconnecting causes automatic shutdown. |
| INPUT 4 (Pin 2) | Digital control input | CMOS-compatible (VIL = 1.25 V, VIH = 3.25 V); drives Channel 4 high-side switch. |
| C.SENSE (Pin 3) | Analog current sense output | Multiplexed output delivering IOUTx/K voltage; shared across multiple VNQ05XSP16 devices via SENSENABLE. |
| SENSENABLE (Pin 4) | Sense line enable | Active-high control enabling/disabling device contribution to shared C.SENSE bus; prevents contention. |
| N.C. (Pin 5) | No connect | Internally unconnected; must be left floating or tied to GND per layout guidelines. |
| INPUT 1 (Pin 6) | Digital control input | Drives Channel 1; identical logic thresholds and leakage (<1 µA) as INPUT 4. |
| INPUT 2 (Pin 7) | Digital control input | Drives Channel 2; supports simultaneous multi-channel activation with independent fault reporting. |
| INPUT 3 (Pin 8) | Digital control input | Drives Channel 3; all four inputs tolerate −0.7 to 6.8 V clamp voltage during transients. |
| SELA (Pin 9) | Channel select A | Binary address bit (LSB) for analog mux; selects IOUT1 or IOUT3 when SENSENABLE = H. |
| SELB (Pin 10) | Channel select B | Binary address bit (MSB) for analog mux; selects IOUT2 or IOUT4 when SENSENABLE = H. |
| VCC (Pin 11) | Supply input | 41 V absolute max; internal clamp protects against low-energy spikes; powers all channels and logic. |
| N.C. (Pin 12) | No connect | Internally unconnected; no routing required. |
| OUTPUT 1 (Pin 13) | High-side switched output | Drives load between this pin and GND; supports inductive loads with Vdemag clamping. |
| OUTPUT 2 (Pin 14) | High-side switched output | Independent channel with same RON, current limit, and protection as OUTPUT 1. |
| OUTPUT 3 (Pin 15) | High-side switched output | Third channel; shares thermal shutdown but has individual overcurrent detection. |
| OUTPUT 4 (Pin 16) | High-side switched output | Fourth channel; fully independent operation with dedicated fault signaling via sense line voltage shift. |
Key Features
| Feature | Design Value |
|---|---|
| Multiplexed analog current sense | Single C.SENSE pin reports IOUT1–4 proportionally (K = 800–1200 A/A) with <±8% drift, reducing MCU ADC channel count and PCB routing. |
| Reverse battery protection support | Enables robust system-level protection using external DGND diode or RGND resistor (≤600 mV drop), validated per datasheet schematic (p.9). |
| Loss-of-ground detection | Automatic channel disable and fault flag assertion if GND pin disconnects - critical for safety-critical chassis-grounded systems. |
| ISO 7637-2 Class C compliance | Survives all five standardized automotive transients (P1–P5) without functional interruption or parametric shift - verified per test table (p.7). |
| Thermal hysteresis | 15 °C reset margin (TR = 135 °C after TTSD = 150 °C) prevents oscillation during sustained overload near thermal limit. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side smart power switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IPS2050H | Single-channel, 5 A rated; no multiplexed current sense; uses SPI interface instead of analog mux. | Lacks quad integration and shared analog sense - requires separate sense paths or MCU with more ADC inputs. | Choose when digital diagnostics, programmable current limit, or daisy-chain configuration are prioritized over analog simplicity. |
| BTS724G | Quad-channel, 5.5 A rated; includes embedded PWM controller; no SELA/SELB mux - provides separate sense pins per channel. | Higher pin count (20-pin TSDSO); lacks shared C.SENSE bus - increases routing complexity but improves channel isolation. | Prefer when independent per-channel diagnostics and higher peak current (5.5 A) outweigh shared-sense convenience. |
Compared with VNQ05XSP16, IPS2050H trades channel count and analog simplicity for digital configurability, while BTS724G offers higher current and per-channel sensing at the cost of larger footprint and no sense bus sharing - making VNQ05XSP16 optimal for space-constrained, analog-diagnostic-focused quad-switch designs.

FAQ
What is the maximum continuous output current per channel?
The VNQ05XSP16 supports 5 A continuous output current per channel at Tcase ≤ 25 °C with adequate PCB copper area (≥0.5 cm²). Derating applies above 25 °C - at 100 °C case temperature, maximum continuous current drops to approximately 3.2 A due to thermal foldback and RON increase (220 mΩ @ 150 °C).
How does the multiplexed current sense work with multiple devices?
Each VNQ05XSP16 uses SENSENABLE to enable its contribution to the shared C.SENSE line. When SENSENABLE is high, the selected channel (via SELA/SELB) drives IOUTx/K onto the line; when low, it presents high impedance. This allows up to N devices on one sense line without external multiplexers or contention.
Does VNQ05XSP16 support reverse battery conditions?
Yes - the device itself does not tolerate reverse VCC, but the datasheet provides two validated external protection networks (resistor RGND or diode DGND in ground path) that enable full reverse-battery operation down to −14 V, with power dissipation managed per design equations on page 9.
What is the purpose of the SELA and SELB pins?
SELA and SELB are binary address inputs that configure the internal analog multiplexer to route one of the four channel currents (IOUT1–IOUT4) to the C.SENSE pin. SELA = L/SELB = L selects Channel 1; H/L = Channel 2; L/H = Channel 3; H/H = Channel 4 - enabling single-point current monitoring per enabled device.
