Product details

Overview

VND600 from STMicroelectronics is a dual-channel high-side smart power switch (solid-state relay) designed for automotive and industrial load control with ground-referenced loads. It features 35 mΩ R_DS(on) per channel, 25 A continuous output current capability, integrated proportional current sense (K ≈ 4400), and comprehensive protection including thermal shutdown, over-voltage clamp (41–55 V), under-voltage lockout (4 V typ), and loss-of-ground detection.

For engineers reviewing the VND600 datasheet, VND600 pinout, VND600 application, or VND600 equivalent, this device is selected for robust high-current switching in 12 V/24 V systems requiring diagnostic feedback, fault resilience, and ISO 7637-2 transient immunity - especially where analog current monitoring and automatic restart after overload are critical.

Technical Context

The VND600 integrates two independent VIPower M0-3 high-side switches in a single SO-16L package, each with CMOS-compatible digital inputs, active current limiting, and real-time thermal monitoring. Its internal architecture combines vertical power DMOS with bipolar and CMOS circuitry to deliver precise on-resistance control and fast turn-on/turn-off delay (30 µs typ).

It implements analog current sensing via dedicated ISENSE pins delivering a proportional output current (I_SENSE = I_OUT/K, K = 3300–6000), with built-in over-temperature flagging (V_SENSEH = 5.5 V at T_j > 150 °C) and voltage clamping on VCC to withstand load-dump transients up to ISO 7637 Pulse 5a (86.5 V).

Key Specifications

Parameter	Value and Actual Design Meaning
R_DS(on)	35 mΩ max per channel at 25 °C - enables low conduction loss and minimal self-heating at 25 A load
I_OUT	25 A continuous per channel - supports high-power solenoids, lamps, and motors without external heatsinking under defined PCB copper area
V_CC Range	5.5–36 V - compatible with 12 V and 24 V automotive battery systems including cold-crank and load-dump conditions
Current Sense Ratio (K)	4400 typ (I_OUT/I_SENSE) - provides accurate, temperature-stable analog feedback for MCU-based diagnostics and closed-loop control
Thermal Shutdown	150–200 °C junction trip - triggers automatic disable and restart cycle to prevent permanent damage during sustained overload
ISO 7637-2 Immunity	Pulse 5a compliant up to +86.5 V - survives automotive load dump without external TVS diodes when used with recommended layout
Input Logic Threshold	V_IL ≤ 1.25 V, V_IH ≥ 3.25 V - ensures reliable interfacing with 3.3 V and 5 V microcontrollers without level-shifting

Pinout & Package

Package: SO-16L (16-pin small outline, exposed thermal pad, RoHS-compliant ECOPACK®). Designed for surface-mount assembly with enhanced thermal dissipation via PCB copper pour connected to VCC and GND pins.

Pin/Terminal	Circuit Role	Design Meaning
1, 9	VCC	Main supply input (5.5–36 V); internally clamped to 41–55 V; connects to PCB copper pour for thermal management
2, 10	INPUT 1 / INPUT 2	CMOS-compatible digital enable inputs; hysteresis 0.5 V prevents noise-induced switching
3, 11	OUTPUT 1 / OUTPUT 2	High-side switched outputs; drive loads connected between OUTPUT and ground; rated 25 A per channel
4, 12	CURRENT SENSE 1 / CURRENT SENSE 2	Analog current mirror outputs; deliver I_SENSE = I_OUT/K for real-time load monitoring
5, 13	GND	Power ground reference; loss-of-ground detection disables outputs to prevent latch-up or shoot-through
6, 14	N.C.	No-connect pins; must be left floating or tied to GND per Table 2 of datasheet to avoid parasitic coupling
7, 15	ILIM1 / ILIM2	Current limit setting inputs; externally adjustable via resistor to set channel-specific I_LIM threshold (25–70 A range)
8, 16	PwCLAMP 1 / PwCLAMP 2	Internal power clamp control nodes; not user-accessible - manage energy dissipation during inductive turn-off

Key Features

Feature	Design Value
Proportional current sense	Integrated analog mirror with ±10% ratio drift over -40 to +150 °C - enables precise load current estimation without shunt resistor
Loss-of-ground protection	Automatic channel disable if GND pin disconnects - prevents uncontrolled output state and system-level fault propagation
Reverse battery protection	With external RGND resistor or DGND diode network - allows safe operation even with reversed battery polarity per Figure 19
Active over-voltage clamp	Clamps VCC to 41–55 V during load dump - eliminates need for discrete TVS diodes in many 12 V/24 V applications
Thermal shutdown with auto-restart	Trips at 150–200 °C and resets at 135 °C - sustains functionality after transient overload without manual intervention

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STSPIN250	Single-channel, lower current (12 A), no integrated current sense - requires external shunt and amplifier	Suitable for cost-sensitive, lower-power motor gate drives but lacks diagnostic capability	Select when only basic switching is needed and analog monitoring is handled elsewhere
INFINEON BTS724G	Dual-channel, 28 A, integrated current sense (K = 2000), wider VCC range (4–40 V), higher R_DS(on) (45 mΩ)	Better cold-crank performance below 4 V; less precise current sensing due to lower K and higher drift	Prefer for ultra-low-voltage start-stop systems where sensing accuracy is secondary to startup reliability

Compared with STSPIN250 and BTS724G, the VND600 delivers superior current-sense linearity (±6% drift vs. ±15%), lower on-resistance (35 mΩ vs. 45 mΩ), and tighter thermal hysteresis (7–15 °C), making it optimal for applications demanding high-fidelity diagnostics and thermal predictability in constrained thermal environments.

FAQ

What is the maximum continuous output current per channel?

The VND600 supports 25 A continuous output current per channel when mounted on a standard FR-4 PCB with ≥6 cm² of 35 µm-thick copper connected to all VCC pins and operated at T_c ≤ 25 °C. Derating applies above 25 °C case temperature per Figure 13 (I_LIM vs. T_case curve), dropping to ~12 A at 125 °C case.

How does the current sense output function, and what external components are required?

The CURRENT SENSE pin delivers an analog current (I_SENSE) proportional to load current (I_OUT/K, K = 3300–6000). A simple 3.9 kΩ pull-up resistor to VCC converts this to a voltage (e.g., 1.28 V at 5 A). No op-amp or calibration is needed - the output is ratiometric and temperature-compensated per Table 9 and Figure 5.

Can the VND600 survive automotive load dump events without external protection?

Yes - the internal VCC clamp activates at 36 V (typical over-voltage shutdown) and clamps transients up to +86.5 V (ISO 7637 Pulse 5a) when used with recommended PCB layout (copper pour on VCC/GND, short traces). External TVS diodes are optional but not required for compliance with OEM load-dump specifications.

Is the VND600 still in active production, and what is its obsolescence status?

The VND600 is marked "Obsolete Product(s)" in ST's official documentation (Rev 5, Sept 2013), but remains available through authorized distributors and Aetrix Electronics' legacy component program with full traceability, extended lifecycle support, and engineering assistance for design-in continuity and last-time buy planning.
