Product details
Overview
VND10BSPTR-E from STMicroelectronics is a dual-channel high-side smart power solid-state relay in PowerSO-10 package, designed for automotive and industrial load switching with grounded-load topology. It delivers 3.4 A nominal output current per channel at VCC = 13 V, features 0.1 Ω on-state resistance, integrated thermal shutdown (140–180 °C), under-voltage lockout (4.5 V typ), and open-drain diagnostic output for fault discrimination.
For engineers reviewing the VND10BSPTR-E datasheet, VND10BSPTR-E pinout, VND10BSPTR-E application, or VND10BSPTR-E equivalent, key selection criteria include ISO-compliant high-side switching capability, inductive load demagnetization (-18 V), dual-channel independent control with shared diagnostic, and 14 A continuous current rating at Tc = 85 °C.
Technical Context
The VND10BSPTR-E integrates two vertical DMOS power switches with dedicated logic inputs and a common open-drain status output. Each channel includes overtemperature protection triggered at ≥140 °C with 50 °C hysteresis, undervoltage detection at 4.5 V (typ), and fast inductive demagnetization via internal clamp to -18 V.
Its diagnostic logic distinguishes open-load (on/off state), thermal shutdown, and stuck-on-to-VCC faults using time-differentiated status pulses: tpol = 50–2500 µs for open-load, tpovl = 5–10 µs for overtemperature-enabling firmware-level fault classification without external circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS(max) | 40 V - Withstands battery transients up to ISO 7637-2 Pulse 1/2a without external clamping |
| RDS(on) | 0.1 Ω (max) - Enables ≤1.2 V drop at 7.5 A, reducing conduction loss in 12 V systems |
| IOUT (cont.) | 14 A @ Tc = 85 °C - Dual-channel derated total current for PCB-mounted thermal design |
| VSTAT (low) | 0.4 V @ ISTAT = 1.6 mA - Ensures clean low-level signal for microcontroller GPIO input detection |
| toff (max) | 500 µs - Supports PWM switching up to ~2 kHz while maintaining safe demag timing margins |
| VDEMAG | -18 V - Limits flyback voltage during inductive turn-off, reducing MOSFET stress and EMI |
| VUSD | 4.5 V (typ) - Prevents erratic switching during cold-crank battery dips below 6 V |
Pinout & Package
Package: PowerSO-10 (exposed die pad, thermally enhanced surface-mount). Pin count: 10. Mounting requires minimum recommended copper pad on FR-4 for Rthj-case = 1.65 °C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (GND) | Power ground reference | Common return for internal logic and power stage; disconnecting disables operation |
| 2 (IN1) | Channel 1 logic input | 5 V-compatible TTL/CMOS input with 0.2–1.5 V hysteresis for noise immunity |

| 5 (OUT2) | Channel 2 high-side output | Dual-output capability enables redundant or complementary load control |
| 6 (VCC) | Supply input | 6–26 V range; internal UVLO activates below 4.5 V |
| 7 (STAT) | Open-drain diagnostic output | Shared fault indicator; pulled high externally to detect open-load, overtemp, stuck-on |
| 8 (NC) | No connect | Internally unconnected; must be left floating or tied to GND per layout guidelines |
| 9 (NC) | No connect | Internally unconnected; no routing required |
| 10 (EPAD) | Exposed thermal pad | Electrically connected to GND; mandatory soldering to PCB copper for thermal performance |
Key Features

| Time-discriminated fault reporting | tpol (50–2500 µs) vs. tpovl (5–10 µs) enables software-based fault root-cause identification |
| Thermal protection with hysteresis | Shuts down at 140–180 °C; auto-restarts at 125 °C, preventing thermal runaway |
| Low standby power dissipation | 35–100 µA supply current in off-state reduces parasitic drain in always-on modules |

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 |
|---|---|---|---|
| IPS1021HTR | Single-channel, 10 A rated, lower RDS(on) (0.045 Ω), integrated current sense | Lacks dual-channel integration and time-discriminated diagnostics; requires external fault decoding | Select when single-load control with precision current monitoring is prioritized over dual-channel compactness |
| TPS2HB35-Q1 | Dual-channel, 3.5 A per channel, SPI-configurable diagnostics, higher VCC max (36 V) | Requires SPI interface and external level-shifting for 3.3 V MCUs; no native -18 V demag clamp | Select when system-level configurability and ASIL-B compliance outweigh analog simplicity and passive demag performance |
Compared with IPS1021HTR and TPS2HB35-Q1, the VND10BSPTR-E offers unique dual-channel integration with hardware-based fault discrimination and passive -18 V demagnetization-reducing firmware complexity and external component count in cost-sensitive 12 V automotive modules.

FAQ
What is the maximum continuous output current per channel at Tc = 85 °C?
The VND10BSPTR-E supports 14 A continuous output current per channel when case temperature is maintained at 85 °C, verified under specified thermal conditions with minimum recommended PCB copper area. This rating assumes proper heatsinking via the exposed EPAD and accounts for both channels operating simultaneously under worst-case ambient conditions.
How does the diagnostic output distinguish between open-load and overtemperature faults?
The STAT pin uses time-differentiated pulse widths: an open-load condition generates a status pulse with duration tpol = 50–2500 µs, while overtemperature produces a shorter tpovl = 5–10 µs pulse after the input falls. This hardware-level timing difference allows microcontroller firmware to identify fault type without additional sensors or complex analog circuitry.
Can the VND10BSPTR-E drive inductive loads without external freewheeling components?
Yes-the device integrates an internal demagnetization clamp that limits flyback voltage to -18 V, eliminating the need for external freewheeling diodes in most 12 V automotive applications. This reduces board space and EMI, though external TVS may still be advised for extreme transients beyond ISO 7637-2 Pulse 5a.
What is the recommended PCB layout practice for thermal performance?
Mount the VND10BSPTR-E on a minimum 25 mm² copper pad connected to internal ground planes via ≥4 thermal vias (0.3 mm diameter). The exposed EPAD (Pin 10) must be soldered directly to this pad. Avoid routing signal traces under the device; use symmetric copper distribution to ensure uniform heat spreading across the thermal path.
