Product details

Overview

VND10B from STMicroelectronics is a dual-channel high-side smart power solid-state relay designed for automotive and industrial load switching with grounded-load topology. It delivers 14 A continuous output per channel at T_c = 85 °C, features 5 V logic-compatible inputs, integrated thermal shutdown (140–180 °C), under-voltage lockout (3.5–6 V), and open-drain diagnostic output for fault reporting. Used in body control modules to drive lamps, solenoids, and relays.

For engineers reviewing the VND10B datasheet, VND10B pinout, VND10B application, or VND10B equivalent, key selection criteria include channel independence with shared diagnostic, inductive load demagnetization (−18 V), low standby current (35–100 µA), R_DS(on) ≤ 0.1 Ω, and ISO-compliant nominal current (3.4 A @ 13 V, T_c = 85 °C).

Technical Context

The VND10B integrates two independent VIPower high-side switches with shared status output, enabling simultaneous monitoring of open-load (on/off), overtemperature, and stuck-on-to-V_CC faults. Each channel includes dedicated thermal sensing inside its MOSFET die and fast demagnetization circuitry generating −18 V clamp during inductive turn-off.

Its protection architecture operates without external components: undervoltage lockout triggers at 3.5–6 V, thermal shutdown activates at 140–180 °C with 50 °C hysteresis, and diagnostic timing discriminates fault types via t_povl (5–10 µs) and t_pol (50–2500 µs) delays.

Key Specifications

Parameter	Value and Actual Design Meaning
Output Current (per channel)	14 A continuous @ T_c = 85 °C - supports high-power automotive loads without forced cooling
R_DS(on)	0.065–0.1 Ω @ I_OUT = I_n, V_CC = 13 V, T_j = 25 °C - enables low conduction loss and <0.5 V drop at nominal current
Nominal Current I_n	3.4 A @ T_c = 85 °C, V_CC = 13 V, V_DS(on) ≤ 0.5 V - ISO-defined rating for automotive high-side switch qualification
Diagnostic Output	Open-drain status pin indicating open-load (on/off), overtemperature, or stuck-on - enables single-wire fault classification in ECUs
Demagnetization Voltage	−18 V typical - reduces inductive energy dissipation by accelerating current decay and limiting V_DS overshoot
Thermal Shutdown Threshold	140–180 °C with 50 °C hysteresis - allows automatic recovery at 125 °C after fault removal
Supply Voltage Range	6–26 V - compatible with 12 V automotive battery systems including load-dump transients

Pinout & Package

PENTAWATT package (vertical, horizontal, or in-line variants), thermally enhanced TO-220–like outline with isolated heatsink tab. Junction-to-case thermal resistance ≤ 1.65 °C/W enables direct mounting to chassis or heatsink.

Pin/Terminal	Circuit Role	Design Meaning
GND	Power ground reference	Common return for both channels and diagnostic; disconnecting disables both outputs
V_CC	Positive supply input	Accepts 6–26 V; reverse-battery protection requires external Schottky diode
IN1 / IN2	Logic-level enable inputs	5 V compatible; VIH ≥ 3.5 V, VIL ≤ 1.5 V, internal 6 V clamp limits overvoltage risk
OUT1 / OUT2	High-side switched outputs	Each drives one side of grounded load; R_DS(on) ≤ 0.1 Ω, V_DS(MAX) ≤ 2 V @ 13 A
STAT	Shared open-drain diagnostic output	Active-low fault indicator; pulled high externally; encodes fault type via timing delays

Key Features

Feature	Design Value
Dual independent high-side switches	Enables redundant or split-load control (e.g., left/right headlamp) with shared diagnostics and no cross-talk
Integrated inductive demagnetization	−18 V clamp reduces turn-off energy loss and eliminates need for external flyback diodes
ISO-compliant nominal current	3.4 A rating defined per ISO standard for automotive high-side switches ensures system-level compliance
Single-wire fault discrimination	STAT pin uses t_povl (5–10 µs) vs. t_pol (50–2500 µs) delays to distinguish overtemperature from open-load conditions
Low quiescent supply current	35–100 µA off-state current minimizes battery drain in always-on vehicle modules

Off-Highway Equipment Lighting

Use Scenario: Controlling trailer brake lights, turn signals, and ABS solenoids across long cable harnesses with voltage drop compensation.

IC Role / Device Role / Timing Role: Dual-channel high-side driver with open-load detection on both states to verify lamp filament integrity before and after activation.

Use Value: Detects broken filaments or disconnected connectors without additional sense lines-reducing wiring complexity and diagnostic false positives.

Use Scenario: Powering LED arrays and halogen work lights on construction, mining, and agricultural machinery operating in wide temperature ranges.

IC Role / Device Role / Timing Role: Robust high-side switch tolerant of 26 V supply transients and −40 to +150 °C junction operation.

Use Value: Maintains stable output regulation during cold-cranking (6 V) and load-dump (≥26 V) events without external regulators or TVS devices.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STSPIN250	Single-channel, 5 A rated, integrated current sense, SPI interface	Lacks dual-channel integration and shared diagnostic; requires microcontroller communication	Select when precise current monitoring and programmable protection thresholds are required over simplicity and analog diagnostics
VND5E025AK	Single-channel, 2.5 A rated, same PENTAWATT package, lower R_DS(on) (0.025 Ω)	No shared diagnostic; separate STAT pins; lower current capacity limits use to smaller solenoids and LEDs	Select for cost-sensitive, lower-current applications where dual-channel coordination is unnecessary

Compared with VND10B, STSPIN250 offers digital configurability but increases system complexity, while VND5E025AK provides better efficiency at low current but sacrifices channel density and diagnostic consolidation-making VND10B optimal for dual-load, analog-diagnostic automotive nodes.

FAQ

What is the maximum continuous output current per channel under real-world thermal conditions?

The VND10B delivers 14 A continuous per channel at case temperature (T_c) = 85 °C with V_CC = 13 V. This rating assumes adequate heatsinking-junction-to-case thermal resistance is ≤1.65 °C/W, so maintaining T_c ≤ 85 °C requires a heatsink thermal resistance ≤ 4.7 °C/W when dissipating 1.2 W per channel at full load.

How does the shared diagnostic (STAT) pin differentiate between open-load and overtemperature faults?

The STAT pin uses time-domain encoding: after input deactivation, a short delay (t_povl = 5–10 µs) indicates overtemperature, while a longer delay (t_pol = 50–2500 µs) indicates open-load. This allows the host MCU to decode fault type using a single GPIO timer capture without additional hardware.

Can VND10B safely drive inductive loads without external freewheeling components?

Yes-the device integrates active demagnetization that clamps the output to −18 V during turn-off, eliminating the need for external flyback diodes. This reduces board space and prevents voltage overshoot exceeding 40 V (V_(BR)DSS), provided layout minimizes parasitic inductance in the load path.

Is reverse-battery protection built-in, or does it require external circuitry?

Reverse-battery protection is not built-in. The absolute maximum reverse supply voltage is −4 V. To withstand −26 V reverse battery, a Schottky diode must be placed between pin 1 (GND) and system ground. Alternative implementation connects the control unit's signal ground to pin 1, allowing use of a standard diode and avoiding VIH/VIL shifts.
