Product details

Overview

VNQ05XSP16TR-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=800–1200 A/A), and integrated protections including undervoltage shutdown (4V typ), overvoltage clamp (48V typ), thermal shutdown (150°C), and reverse battery protection. It is used in body control modules for driving lamps, solenoids, and actuators.

For engineers reviewing the VNQ05XSP16TR-E datasheet, VNQ05XSP16TR-E pinout, VNQ05XSP16TR-E application, or VNQ05XSP16TR-E equivalent, key selection criteria include per-channel R_ON (110 mΩ @ 25°C), ISO 7637-2 transient immunity (Class C up to Pulse 5a), PowerSO-16™ package thermal resistance (R_thj-case = 1.6 °C/W), and multiplexed analog current sense with 300–500 µs delay.

Technical Context

The VNQ05XSP16TR-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 includes active current limiting (5–10 A), thermal foldback, and loss-of-ground detection that forces automatic shutdown.

Its protection architecture combines voltage clamping (V_clamp = 48 V), overvoltage shutdown (V_OV = 36 V), and under-voltage lockout (V_USD = 4 V) with internal demagnetization control for inductive loads and reverse-battery tolerance via external RGND/DGND networks as specified in the application schematic.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CC Range	5.5–36 V - supports 12 V and 24 V automotive battery systems with transient tolerance up to +86.5 V (ISO 7637 Pulse 5)
R_ON (per channel)	110 mΩ @ T_j = 25°C - enables low conduction loss (≤0.275 W at 5 A), reducing heatsink requirements
I_OUT (cont.)	5 A per channel - rated for sustained resistive and inductive loads including headlamps and fuel pumps
Current Sense Ratio K	800–1200 A/A - provides scalable analog feedback (e.g., 1 mA sense current = 0.8–1.2 A load current) for closed-loop monitoring
T_j Shutdown Threshold	150°C - triggers thermal shutdown with 15°C hysteresis (T_R = 135°C) to prevent permanent damage during overload
Turn-on/off Delay	40 µs - ensures deterministic timing for synchronized multi-channel sequencing in BCU applications
Reverse Battery Protection	Supported via external DGND diode or RGND resistor network - prevents latch-up and destruction during -12 V or -24 V fault conditions

Pinout & Package

Package: PowerSO-16™ - thermally enhanced surface-mount package with exposed die pad for low R_thj-case (1.6 °C/W) and high power dissipation (78 W @ T_case = 25°C).

Pin/Terminal	Circuit Role	Design Meaning
GND (Pin 1)	Power Ground Reference	Common return path for all channels; disconnect detection triggers automatic shutdown
INPUT 4 (Pin 2)	Channel 4 Digital Input	CMOS-compatible (V_IL = 1.25 V, V_IH = 3.25 V); drives internal gate driver for OUT4
C.SENSE (Pin 3)	Multiplexed Analog Current Sense Output	Delivers I_OUTn/K voltage (0–4 V) for selected channel; requires external R_SENSE (e.g., 3.9 kΩ)
SENSENABLE (Pin 4)	Current Sense Enable Control	Active-high signal enabling analog mux; allows multiple VNQ05XSP16 devices on shared sense line
N.C. (Pin 5)	No Connect	Internally unused; must be left unconnected or tied to GND per layout guidelines
INPUT 1 (Pin 6)	Channel 1 Digital Input	Same logic thresholds and leakage (<1 µA) as INPUT 4; controls OUT1 independently
INPUT 2 (Pin 7)	Channel 2 Digital Input	Independent control input with hysteresis (0.5 V) for noise immunity in harsh environments
INPUT 3 (Pin 8)	Channel 3 Digital Input	Supports PWM dimming or duty-cycle control of connected loads without external buffering
SELA (Pin 9)	Sense Channel Select A	LSB of 2-bit mux address; selects I_OUT1, I_OUT2, I_OUT3, or I_OUT4 for C.SENSE output
SELB (Pin 10)	Sense Channel Select B	MSB of 2-bit mux address; combined with SELA, enables full 4-channel analog readout
V_CC (Pins 11,12)	Power Supply Input	Dual V_CC pins reduce IR drop and improve transient immunity; clamped to 48 V internally
N.C. (Pin 13)	No Connect	Unused terminal; no internal connection - avoid routing traces or vias
OUTPUT 1 (Pin 14)	Channel 1 High-Side Switch Output	Drives load between V_CC and load; supports inductive kickback with active demag control
OUTPUT 2 (Pin 15)	Channel 2 High-Side Switch Output	Electrically isolated from other outputs; each channel has independent current limit and thermal sensing
OUTPUT 3 (Pin 16)	Channel 3 High-Side Switch Output	Rated for 5 A continuous; short-circuit protection activates within microseconds at >7.5 A
OUTPUT 4 (Pin 17)	Channel 4 High-Side Switch Output	Final output terminal; shares same protection stack (OV, UV, OT, ILIM) as other channels

Key Features

Feature	Design Value
Quad independent high-side switches	Enables simultaneous control of four separate 12 V/24 V loads (e.g., fog lights, HVAC actuators, door locks) without cross-talk
Multiplexed proportional current sense	Reduces BOM count by eliminating four separate sense amplifiers; supports diagnostics via single ADC input
Loss-of-ground detection	Monitors GND pin continuity; shuts down all channels if ground opens - critical for functional safety in chassis-mounted ECUs
ISO 7637-2 Class C immunity	Withstands automotive transients (Pulse 1–5) without latch-up or parameter shift - validated per test levels in datasheet Table 7
Very low standby power dissipation	80 µA supply current in off-state - extends battery life in always-on modules (e.g., gateway ECUs, telematics)

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STSPIN250	Single-channel, 5 A rated, no current sense output, lower R_ON (80 mΩ), no multiplexing	Lacks quad integration and analog sense - requires four ICs and external sensing for same functionality	Select when space permits discrete channel layout and current monitoring is handled externally
TPS4H160-Q1	Quad-channel, 4 A rated, integrated diagnostics (open-load, short-to-VCC), SPI interface, higher quiescent current (250 µA)	Provides digital communication and richer fault reporting but lacks proportional analog sense output	Select when CAN/SPI-based diagnostics and ASIL-B support are required over analog current feedback

Compared with STSPIN250 and TPS4H160-Q1, the VNQ05XSP16TR-E uniquely balances quad integration, true proportional current sensing, and automotive-grade transient robustness in a single PowerSO-16™ package - making it optimal for cost-sensitive, analog-diagnostic-focused BCM designs.

FAQ

What is the maximum continuous output current per channel?

The VNQ05XSP16TR-E supports 5 A continuous output current per channel at T_case ≤ 150°C with proper PCB copper area (≥0.5 cm² per V_CC pin). Derating applies above 100°C case temperature per Figure 10 in the datasheet, where I_LIM decreases from 7.5 A at 25°C to 5 A at 125°C.

How does the multiplexed current sense work with SELA/SELB pins?

SELA (Pin 9) and SELB (Pin 10) form a 2-bit address selecting which channel's current is routed to C.SENSE (Pin 3): SELA=0/SELB=0 → I_OUT1, 0/1 → I_OUT2, 1/0 → I_OUT3, 1/1 → I_OUT4. SENSENABLE (Pin 4) must be high to enable the mux; all channels share the same K ratio (800–1200 A/A).

Can VNQ05XSP16TR-E withstand reverse battery conditions?

Yes - reverse battery protection is implemented externally using either a series resistor (RGND ≤ 600 mV / I_S(on)max) or a Schottky diode (DGND) in the ground path, as detailed in Figure 9 and Section 9 of the datasheet. The IC itself tolerates -0.3 V on V_CC and -5 V on outputs, but full protection requires the recommended external network.

Is thermal shutdown latched or auto-restarting?

Thermal shutdown is auto-restarting: when junction temperature exceeds T_TSD = 150°C, the device disables all outputs; it automatically resumes operation once T_j falls below T_R = 135°C (15°C hysteresis). This behavior is confirmed in the Truth Table (Page 6) and Thermal Data section (Page 4).
