Product details

Overview

VND05BSP from STMicroelectronics is a dual-channel ISO-compliant high-side smart power solid-state relay built with VIPower technology, designed for automotive and industrial load switching where one side of the load is grounded. It delivers 1.6 A nominal continuous output current per channel (9 A at Tc = 85 °C), features 0.2 Ω R_DS(on), 40 V V_DSS, and integrated open-load/over-temperature diagnostics via an open-drain status pin - used in body control modules for driving solenoids and lamps.

For engineers reviewing the VND05BSP datasheet, VND05BSP pinout, VND05BSP application, or VND05BSP equivalent, key selection considerations include thermal shutdown threshold (140–180 °C), under-voltage lockout (3.5–6 V), diagnostic delay timing (tpol = 50–2500 µs), and inductive demagnetization capability (−18 V clamp).

Technical Context

The VND05BSP integrates two independent high-side power switches with shared diagnostic logic and thermal sensing directly embedded in the power MOS structure. Each channel supports 5 V logic-compatible input with 0.2–1.5 V hysteresis and clamped VIH up to 6 V, enabling direct microcontroller interfacing without level-shifting.

Its protection architecture includes fast short-circuit response via junction-localized thermal sensing, programmable undervoltage shutdown, and dual-mode fault discrimination: open-load detection in both ON and OFF states using distinct status pulse widths (tpovl = 5–10 µs, tpol = 50–2500 µs), plus stuck-on-to-VCC detection.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	40 V - Maximum drain-source blocking voltage; defines safe operation with 12 V automotive battery + load dump transients.
R_DS(on)	0.2 Ω (typ.) - On-resistance at V_CC = 13 V, T_j = 25 °C; determines conduction loss and thermal rise under 1.6 A nominal load.
I_OUT (cont.)	9 A @ T_c = 85 °C - Continuous per-channel current rating under heatsink-cooled conditions; sets PCB copper area and thermal pad design requirements.
V_STAT (low)	0.4 V @ I_STAT = 1.6 mA - Diagnostic output low-level voltage; ensures reliable TTL/CMOS logic recognition by host controller.
T_SD	140–180 °C - Thermal shutdown activation range; triggers automatic channel disable to prevent silicon damage during overload or poor heatsinking.
V_USD	3.5–6 V - Undervoltage shutdown threshold; prevents erratic switching or latch-up during brown-out or cold-cranking conditions.
V_demag	−18 V - Internal inductive flyback clamp voltage; enables fast demagnetization of solenoids/relays while limiting peak V_DS stress.

Pinout & Package

Package: PowerSO-10™ - thermally enhanced surface-mount package with exposed die-pad for efficient heat transfer to PCB ground plane; requires minimum FR-4 pad size per ST's thermal data (R_thj-case = 2.1 °C/W).

Pin/Terminal	Circuit Role	Design Meaning
1 (GND)	Power Ground Reference	Common return path for internal circuitry and thermal pad; disconnecting this pin disables device if V_CC ≤ 16 V.
2 (IN1)	Channel 1 Logic Input	5 V-compatible digital enable signal; VIH ≥ 3.5 V, VIL ≤ 1.5 V, with 0.2–1.5 V hysteresis for noise immunity.
3 (OUT1)	Channel 1 High-Side Output	Switched 12/24 V load connection; supports resistive/inductive loads with integrated demag clamp (−18 V).
4 (IN2)	Channel 2 Logic Input	Independent second control input; identical electrical specs to IN1; enables dual-load control from single IC.
5 (OUT2)	Channel 2 High-Side Output	Second switched output; shares diagnostic logic but operates independently; R_DS(on) matched to OUT1.
6 (V_CC)	Supply Voltage Input	8–26 V operating range; includes internal UVLO (3.5–6 V) and reverse-battery protection interface support.
7 (STAT)	Open-Drain Diagnostic Output	Single-wire fault reporting: low = overtemp/open-load-on; high = normal or open-load-off; pulse width discriminates fault type.
8–10 (PAD)	Thermal & Electrical Ground	Exposed die-pad connected internally to GND; must be soldered to large copper pour for R_thj-case = 2.1 °C/W performance.

Key Features

Feature	Design Value
Dual high-side channels with shared diagnostic	Reduces BOM count and PCB area vs. two discrete switches; STAT pin simplifies fault monitoring with single MCU GPIO.
ISO 7637-compliant transient robustness	Withstands automotive load-dump (40 V) and reverse-battery (−26 V with Schottky protection) per typical application circuits.
Inductive load fast demagnetization	Integrated −18 V clamp reduces energy dissipation during turn-off, extending solenoid life and lowering system thermal load.
Thermal shutdown with hysteresis	Shuts down at 140–180 °C and resets at 125 °C; prevents thermal runaway while allowing recovery after transient overload.
5 V logic-compatible inputs	Direct interface with standard microcontrollers without external level shifters; VIH clamped at 6 V for overvoltage tolerance.

FAQ

What is the maximum continuous output current per channel at ambient temperature?

The VND05BSP is rated for 9 A continuous output current per channel at case temperature (T_c) = 85 °C - not ambient. At T_c = 25 °C with proper heatsinking, it supports up to ~12 A briefly, but sustained operation must follow derating curves in the datasheet based on R_thj-amb = 50 °C/W and layout-dependent thermal resistance.

How does the STAT pin distinguish between open-load and overtemperature faults?

The STAT pin uses pulse-width encoding: after input deactivation, a short low pulse (5–10 µs, tpovl) indicates open-load-in-OFF-state, while a longer pulse (50–2500 µs, tpol) indicates open-load-in-ON-state or overtemperature. Overtemperature produces immediate low assertion upon detection, with recovery only after junction cools to 125 °C.

Can VND05BSP drive inductive loads without external components?

Yes - it includes an internal −18 V demagnetization clamp that safely dissipates inductive energy during turn-off. No external flyback diode is required for standard solenoids or relays. However, for very high-energy inductors or strict EMC requirements, an external RC snubber may still be recommended per application testing.

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

Reverse-battery protection is not fully integrated - the device tolerates only −4 V reverse supply voltage. For full −26 V reverse-battery survival (per ISO 16750), a Schottky diode must be placed between Pin 1 (GND) and system ground, as shown in Figure 2 of the datasheet. Alternative grounding schemes can eliminate forward voltage drop impact on logic thresholds.
