Product details

Overview

VND810SP from STMicroelectronics is a double-channel high-side driver IC designed for automotive and industrial load control, featuring 160 mΩ R_DS(on) per channel, 3.5 A continuous output current, 36 V maximum supply voltage, and PowerSO-10 package. It drives grounded loads with integrated open-load detection (on/off-state), thermal shutdown, undervoltage/overvoltage protection, and reverse battery immunity.

For engineers reviewing the VND810SP datasheet, VND810SP pinout, VND810SP application, or VND810SP equivalent, this device is selected for robust 12 V/24 V DC load switching in engine control units, body electronics, and industrial PLC I/O modules where diagnostic feedback, fault resilience, and low quiescent current are critical.

Technical Context

The VND810SP integrates two independent VIPower™ M0-3 high-side switches with CMOS-compatible inputs and dedicated status pins per channel. Each channel implements active current limiting (3.5–7.5 A), thermal shutdown at 150–200 °C with 135 °C reset hysteresis, and dual-mode open-load detection-measuring output current <20–80 mA (on-state) or output voltage >1.5–3.5 V (off-state).

Its protection architecture includes an internal VCC clamp for ISO 7637-2 pulse compatibility, undervoltage lockout (4 V typ.), overvoltage shutdown (36 V), and output stuck-to-VCC detection. The device automatically disables both channels if GND is disconnected, ensuring fail-safe behavior in harsh environments.

Key Specifications

Parameter	Value and Actual Design Meaning
R_DS(on) (per channel)	160 mΩ @ I_OUT = 1 A, T_j = 25 °C - enables low conduction loss and minimal self-heating at rated load
Max output current	3.5 A continuous - supports driving solenoids, relays, and lamps without external heatsinking under typical ambient conditions
V_CC range	5.5–36 V - compatible with 12 V and 24 V automotive batteries including cold-crank and load-dump transients
Open-load detection	On-state: 20–80 mA threshold; Off-state: 1.5–3.5 V threshold - provides unambiguous fault reporting without external circuitry
Thermal shutdown	150–200 °C trip, 135 °C reset - prevents permanent damage during sustained overload while enabling automatic recovery
Quiescent current	12–40 µA (off-state) - minimizes battery drain in always-on vehicle modules
Switching delay	30 µs typ. turn-on/turn-off - supports PWM control up to ~10 kHz for dimming or proportional actuation

Pinout & Package

Package: PowerSO-10 - thermally enhanced surface-mount package with exposed die pad for efficient heat dissipation; suitable for automotive PCB layouts requiring high reliability and thermal performance.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 3, 4, 5, 6, 7, 8	Output 1 / Output 2 / GND / Input 1 / Status 1 / Status 2 / Input 2 / V_CC	Top-view pin mapping per Figure 2: Pins 1–2 = OUTPUT1, Pin 3 = GND, Pins 4–5 = INPUT1/STATUS1, Pins 6–7 = STATUS2/INPUT2, Pin 8 = V_CC, Pins 9–10 = OUTPUT2 - dual-channel symmetry with shared ground and supply
9, 10	OUTPUT2	Dedicated high-side output terminals for second load; electrically isolated but thermally coupled to first channel in same island

Key Features

Feature	Design Value
CMOS-compatible input logic	VIH = 3.25 V, VIL = 1.25 V, 0.5 V hysteresis - interfaces directly with 3.3 V/5 V microcontrollers without level-shifting
Active V_CC clamp	Clamps transients up to ISO 7637-2 Pulse 1/2a/3a - eliminates need for external TVS diodes in most automotive applications
Reverse battery protection	Withstands -0.3 V V_CC and -200 mA reverse GND current - prevents damage during incorrect battery connection
Status pin diagnostics	Dual independent STATUS outputs report real-time channel faults (overload, open-load, overtemp, UV/OV) - enables software-based system-level error handling
Load current limitation	Adjustable 3.5–7.5 A limit depending on V_CC and case temperature - balances drive capability with safe SOA operation

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STSPIN820	Single-channel, integrated current sense, no off-state open-load detection, 2.8 A max I_OUT	Lacks dual-channel integration and full diagnostic set; suited for space-constrained motor control only	Select when precise current monitoring is prioritized over dual-load independence and comprehensive fault reporting
BTS716G	Single-channel, 5.5 A rating, identical PowerSO-10 package, no reverse battery protection	Requires external reverse-polarity protection; lacks V_CC clamp for ISO 7637-2 compliance	Select for higher current demand where external TVS and reverse-battery diode are acceptable

Compared with STSPIN820 and BTS716G, the VND810SP uniquely delivers dual-channel operation with full diagnostic coverage (including off-state open-load and reverse battery immunity) in a single PowerSO-10 package-reducing board area, component count, and validation effort for multi-load automotive systems.

FAQ

What is the maximum junction temperature and thermal resistance of the VND810SP?

The VND810SP features internal thermal shutdown at 150–200 °C with 135 °C reset hysteresis. Its thermal resistance junction-to-case is 2.4 °C/W, and junction-to-ambient is 37 °C/W on a 6 cm² copper PCB - enabling 52 W power dissipation per island at T_lead = 25 °C with proper layout.

Does the VND810SP require external components for ISO 7637-2 transient protection?

No. The VND810SP includes an active V_CC clamp that meets ISO 7637-2 Pulse 1, 2a, 3a, and 3b requirements up to ±100 V without external TVS diodes - verified per Table 13 and Figure 11 in the datasheet.

How does the off-state open-load detection work, and what is its threshold?

Off-state open-load detection monitors output voltage when the channel is disabled. If V_OUT rises above 1.5–3.5 V (e.g., due to leakage through a high-impedance load), the STATUS pin asserts low. This occurs within 1000 µs and requires no external pull-up resistor - confirmed in Table 11 and Figure 25.

Can the VND810SP drive inductive loads like solenoids or relays safely?

Yes. The VND810SP incorporates active demagnetization clamping (V_DEMAG = V_CC − 41 to V_CC − 55 V) and current limiting (3.5–7.5 A) to safely handle inductive kickback. Maximum demagnetization energy is specified at 24 mJ for L = 1.4 mH and I_L = 5 A - validated in Section 3.5 and Figure 26.
