Product details

Overview

VND10BSP from STMicroelectronics is a dual-channel high-side smart power solid-state relay IC designed for automotive and industrial load switching with one side grounded. It features 40 V V_DS(BR), 0.1 Ω R_DS(on) (typ.), 3.4 A nominal output current per channel at 13 V V_CC, integrated thermal shutdown, and open-load diagnostics - used in body control modules for driving lamps, solenoids, and relays.

For engineers reviewing the VND10BSP datasheet, VND10BSP pinout, VND10BSP application, or VND10BSP equivalent, key selection criteria include ISO-compliant high-side switching behavior, diagnostic delay timing (tpol/tpovl), inductive demagnetization capability (–18 V), and PowerSO-10 thermal performance (R_thj-case = 1.65 °C/W).

Technical Context

The VND10BSP integrates two independent high-side N-channel power MOSFETs with embedded protection logic, gate drivers, and a shared open-drain diagnostic output. Its internal architecture includes voltage-clamped logic inputs (VIH clamped at ~6 V), undervoltage lockout (VUSD = 4.5 V typ.), and thermal sensing directly coupled to the power die.

Switching behavior follows ISO-defined timing: turn-on delay ≤200 µs, rise time ≤360 µs, fall time ≤360 µs, and fast demagnetization support via –18 V flyback clamping. Diagnostic state decoding relies on differential delay (tpol = 50–2500 µs for open-load-on, tpovl = 5–10 µs for overtemperature) to distinguish fault types without external circuitry.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS(BR)	40 V - Maximum drain-source breakdown voltage; defines safe operating range for 24 V automotive systems with transients.
R_DS(on)	0.1 Ω (max) - On-resistance at T_j = 25 °C, V_CC = 13 V; enables ≤1.2 V drop at 7.5 A, minimizing conduction loss.
I_OUT (cont.)	14 A @ T_c = 85 °C - Continuous per-channel current rating under heatsink conditions; supports high-power solenoid actuation.
V_USD	4.5 V (typ.) - Undervoltage shutdown threshold; prevents erratic switching during battery brownout below nominal 12 V.
T_SD	160 °C (typ.) - Thermal shutdown activation temperature; protects against short-circuit latch-up with 50 °C hysteresis.
V_demag	–18 V - Internal demagnetization clamp voltage; limits inductive kick energy and reduces dissipation in relay/solenoid drive.
t_pol/t_povl	50–2500 µs / 5–10 µs - Diagnostic delay times distinguishing open-load (on/off) vs. overtemperature faults per ISO standard.

Pinout & Package

Package: PowerSO-10 (10-pin exposed-pad surface-mount package with R_thj-case = 1.65 °C/W; requires minimum FR-4 pad size per datasheet Figure 7).

Pin/Terminal	Circuit Role	Design Meaning
1 (GND)	Power ground reference	Common return path for both channels and diagnostic; disconnecting disables operation if V_CC ≤16 V.
2 (IN1)	Channel 1 logic input	5 V-compatible TTL/CMOS input with 0.2–1.5 V hysteresis; internally clamped to 6 V.
3 (OUT1)	Channel 1 high-side output	Drives grounded loads; supports 14 A continuous with integrated short-circuit protection.
4 (IN2)	Channel 2 logic input	Independent 5 V-compatible input; identical electrical specs to IN1.
5 (OUT2)	Channel 2 high-side output	Second independent high-side switch; shares diagnostic but not thermal or current paths.
6 (V_CC)	Supply input	6–26 V operating range; includes undervoltage lockout and reverse-battery protection interface points.
7 (STAT)	Open-drain diagnostic output	Indicates open load (on/off), overtemperature, or stuck-on faults; pulled high externally via resistor.
8–10 (EP)	Exposed thermal pad	Electrically connected to GND; primary heat dissipation path; must be soldered to PCB copper area.

Key Features

Feature	Design Value
Dual independent high-side switches	Two fully isolated 40 V, 14 A channels sharing only diagnostic logic - enables compact dual-load control without cross-talk.
ISO-compliant diagnostic timing	tpol (50–2500 µs) and tpovl (5–10 µs) delays allow firmware-level fault discrimination per ISO 16750-2.
Integrated inductive demagnetization	–18 V internal clamp reduces flyback energy dissipation and eliminates need for external snubbers in relay/solenoid circuits.
Reverse battery protection ready	Supports Schottky diode insertion at GND pin (Pin 1); shifts VIH/VIL thresholds predictably without logic failure.
Low standby power	35–100 µA supply current in off-state - critical for always-on automotive modules meeting ISO 8820 leakage limits.

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, 60 V, R_DS(on) = 0.12 Ω, no integrated diagnostic output	Lacks STAT pin and ISO fault timing; requires external comparator for open-load detection	Choose when dual-channel integration is unnecessary and diagnostic simplicity is acceptable
BTS716G	Single-channel, 40 V, R_DS(on) = 0.016 Ω, integrated current sense and enhanced diagnostics	Higher accuracy current monitoring (±5%), faster t_off (≤100 µs), but higher quiescent current (200 µA)	Prefer for precision current feedback in closed-loop solenoid control, not basic on/off switching

Compared with STSPIN250 and BTS716G, the VND10BSP uniquely delivers dual-channel integration with ISO-aligned diagnostic timing in a single PowerSO-10 package - reducing board space and firmware complexity where two independent, fault-aware switches are required.

FAQ

What is the maximum continuous output current per channel at 85°C case temperature?

The VND10BSP supports 14 A continuous output current per channel at T_c = 85 °C when mounted on a PCB with minimum recommended copper area per the PowerSO-10 mechanical drawing. This rating assumes proper thermal management and accounts for R_thj-case = 1.65 °C/W. Derating applies above 85 °C case temperature per the thermal data table.

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

The STAT pin uses ISO-defined delay timing: an open-load condition (on-state or off-state) triggers a high-to-low transition after t_pol = 50–2500 µs, while overtemperature causes transition after t_povl = 5–10 µs. This differential delay allows microcontroller firmware to identify fault type without additional hardware, using a single GPIO input.

Can the VND10BSP drive inductive loads without external flyback diodes?

Yes - the device integrates a –18 V demagnetization clamp that safely dissipates inductive energy during turn-off. This eliminates the need for external flyback diodes in most solenoid and relay applications, reducing board space and cost. The clamp operates automatically and is rated for continuous use within specified current and frequency limits.

What is the recommended approach for reverse-battery protection?

A Schottky diode between Pin 1 (GND) and system ground provides effective reverse-battery protection against –26 V. This shifts input thresholds (VIH/VIL) and V_STAT upward by the diode forward voltage (V_f). Alternatively, connecting the control unit's signal ground to Pin 1 avoids threshold shifts and allows use of a standard diode, as shown in Figure 3 of the datasheet.
