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 with one side grounded. It delivers 1.6 A nominal continuous output per channel (9 A at Tc = 85 °C), features 0.2 Ω on-state resistance, 40 V V_DSS, and integrated open-load/over-temperature diagnostics - used in body control modules for driving lamps, solenoids, and actuators.

For engineers reviewing the VND05BSP datasheet, VND05BSP pinout, VND05BSP application, or VND05BSP equivalent, key selection criteria include thermal shutdown threshold (140–180 °C), diagnostic delay differentiation (tpovl = 5–10 µs vs. tpol = 50–2500 µs), inductive demagnetization capability (−18 V), and 5 V logic-level compatibility with hysteresis (0.2–1.5 V).

Technical Context

The VND05BSP integrates two independent high-side power switches with shared diagnostic output, each featuring a protected Power MOSFET stage, current-sensing circuitry, and thermal shutdown sensor embedded directly in the power die. Its ISO compliance ensures robustness against automotive transients including reverse battery (−26 V with Schottky protection) and load-dump events.

Switching behavior is defined by precise timing parameters: turn-on delay (5–200 µs), rise time (10–180 µs), and fast demagnetization support enabling controlled energy dissipation in inductive loads via internal −18 V clamp. The status output distinguishes fault types - open load (on/off state), overtemperature, or stuck-on - using differential delay thresholds.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	40 V - maximum drain-source blocking voltage, suitable for 12 V automotive systems with transient margin
R_DS(on)	0.2 Ω - on-resistance at T_j = 25 °C and V_CC = 13 V, enabling low conduction loss at 1.6 A nominal load
I_OUT (cont.)	9 A @ T_c = 85 °C - continuous per-channel current rating under heatsink-cooled conditions
V_USD	3.5–6 V - undervoltage shutdown threshold prevents erratic operation during brown-out conditions
T_TSD	140–180 °C - thermal shutdown activation range with 50 °C hysteresis for automatic recovery at 125 °C
V_DEMAG	−18 V - internally generated demagnetization voltage for rapid inductive load energy dissipation
V_IL/V_IH	1.5 V / 3.5 V - TTL/CMOS-compatible input thresholds with 0.2–1.5 V hysteresis for noise immunity

Pinout & Package

Package: PowerSO-10™ - thermally enhanced surface-mount package with exposed die-pad for efficient heat transfer to PCB copper area (R_thj-case = 2.1 °C/W max).

Pin/Terminal	Circuit Role	Design Meaning
1 (GND)	Power ground reference	Common return path for both channels and diagnostic circuit; disconnecting disables operation if V_CC ≤ 16 V
2 (IN1)	Channel 1 logic input	5 V-compatible digital control signal with internal clamping and hysteresis
3 (OUT1)	Channel 1 high-side output	Switched 12 V supply to load; supports inductive demag and open-load detection
4 (IN2)	Channel 2 logic input	Independent digital control input with same electrical specs as IN1
5 (OUT2)	Channel 2 high-side output	Second independently switched high-side output sharing diagnostic pin
6 (STAT)	Open-drain diagnostic output	Indicates faults: open load (on/off), overtemperature, or stuck-on via pulse-width-coded delays
7–10 (V_CC)	Supply input (4 pins paralleled)	High-current 6–26 V supply connection; multiple pins reduce IR drop and improve thermal performance

Key Features

Feature	Design Value
Dual high-side switching with shared diagnostic	Enables compact BOM for dual-load control (e.g., left/right headlamp) while reducing wiring and connector count
ISO 7637-2 compliant protection	Withstands automotive transients including reverse battery (−26 V) when protected by external Schottky diode
Discriminative fault diagnosis	Uses tpovl (5–10 µs) and tpol (50–2500 µs) delays to distinguish open-load-on from open-load-off conditions
Fast inductive demagnetization	Internal −18 V clamp reduces demag time and power dissipation in solenoid/valve drivers
Very low standby current	35–100 µA supply current in off-state minimizes battery drain in always-on vehicle modules

Applications

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, higher R_DS(on) (0.35 Ω), lower I_OUT (3.5 A), no shared diagnostic	Lacks dual-channel integration and fault discrimination; requires separate status routing	Select when space constraints favor single-channel layout or lower cost outweighs diagnostic richness
VND5E025AK	Single-channel, lower V_DSS (36 V), identical R_DS(on) (0.2 Ω), same diagnostic architecture	Requires two devices for dual-load control; increases PCB area and BOM count	Choose when legacy design uses VND5E-series footprint or needs pin-to-pin upgrade path

Compared with IPS2050H and VND5E025AK, the VND05BSP uniquely delivers dual-channel control with shared diagnostic in a single PowerSO-10 package - reducing system-level complexity, improving fault localization accuracy, and lowering per-channel cost in multi-load automotive modules.

FAQ

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

The VND05BSP supports 9 A continuous output current per channel at case temperature (T_c) = 85 °C when mounted on a PCB with minimum recommended copper pad area (R_thj-amb = 50 °C/W). At T_c = 25 °C, derating allows up to ~12 A, but thermal design must ensure junction temperature remains ≤150 °C under worst-case load and ambient conditions.

How does the diagnostic output differentiate between open-load and overtemperature faults?

The STAT pin uses pulse-width coding: after input deactivation, a short delay (5–10 µs) indicates open-load-in-off-state (tpovl), while a longer delay (50–2500 µs) indicates open-load-in-on-state (tpol); overtemperature causes immediate low-state assertion with no delay. This timing-based encoding enables microcontroller firmware to identify fault type without additional hardware.

Can the VND05BSP drive inductive loads without external flyback components?

Yes - the device integrates an active demagnetization circuit that clamps inductive kickback to −18 V, eliminating need for external diodes or RC snubbers. This feature reduces board space and improves reliability in solenoid, relay, and valve driver applications where fast turn-off and energy control are critical.

What protection features are implemented against reverse battery connection?

The VND05BSP withstands reverse battery only when protected externally: a Schottky diode between Pin 1 (GND) and chassis ground limits reverse voltage to −V_f (~0.4 V), preventing damage. Without this diode, −26 V reverse battery exceeds the −4 V absolute maximum rating and will destroy the device.
