STMicroelectronics VND600SP

Overview

VND600SP from STMicroelectronics is a dual-channel high-side solid-state relay IC designed for driving resistive or inductive loads with one side grounded. It features 30 mΩ R_DS(on) per channel, 25 A DC short-circuit current capability, CMOS-compatible inputs, and proportional analog current sense outputs (K = 4400 typ.) for real-time load monitoring in automotive power distribution systems.

For engineers reviewing the VND600SP datasheet, VND600SP pinout, VND600SP application, or VND600SP equivalent, this device is selected for robust high-side switching in 12 V/24 V vehicle subsystems requiring integrated diagnostics, thermal shutdown, reverse-battery protection, and ISO 7637-2 transient immunity - especially where space-constrained PowerSO-10 packaging and precise current feedback are critical.

Technical Context

The VND600SP integrates two independent VIPower M0-3 high-side switches with dedicated current-sense outputs (ISENSE1/ISENSE2), each delivering 25 A short-circuit current limit and 30 mΩ on-resistance at T_j = 25°C. Its protection architecture includes under-voltage (4 V typ.) and over-voltage (36 V) shutdown, active V_CC clamp (41–55 V), and thermal shutdown at 150°C with 15°C hysteresis.

Each channel supports proportional current sensing with ±6% ratio drift over –40°C to +150°C and 500 µs signal delay; logic inputs accept 3.25 V high-level and 1.25 V low-level thresholds with 0.5 V hysteresis, enabling direct interfacing with automotive MCUs without level-shifting.

Equivalent & Alternatives

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

Compared with STSPIN250, VND600SP delivers double the channel count, 5× higher current rating, and integrated diagnostics - making it superior for automotive body electronics consolidation. Against VND5E025AK, it reduces component count and interconnect risk by integrating both channels in one PowerSO-10 package with shared thermal management.

FAQ

What is the maximum continuous output current per channel?

The VND600SP supports 25 A DC short-circuit current per channel, but continuous current is thermally limited. At T_c = 25°C with 6 cm² PCB copper, maximum continuous current is ~12 A (derated per R_thj-amb = 37°C/W and P_tot = 96.1 W). Real-world design must consider ambient temperature, airflow, and PCB layout to maintain T_j ≤ 150°C.

How does the current sense output behave during thermal shutdown?

During thermal shutdown (T_j ≥ 150°C), the current sense output transitions to a fixed 5.5 V high-impedance state (V_SENSEH), signaling over-temperature condition to the MCU. This occurs independently per channel and remains active until junction temperature drops below the reset threshold (135°C), enabling reliable fault classification without additional sensors.

Can unused input pins be left floating?

No - unused INPUT pins must be tied to GND through a 10 kΩ resistor per ST's Table 2 recommendation. Floating inputs risk unintended channel activation due to noise coupling or leakage, potentially causing uncontrolled load energization or increased standby current. This applies even when only one channel is used.

Is the VND600SP compliant with AEC-Q100?

Yes - the VND600SP is qualified to AEC-Q100 Grade 1 (–40°C to +125°C ambient) and supports extended junction temperature operation up to 150°C. Its design meets automotive reliability standards including HTOL, ESD (HBM 4 kV), and ISO 7637-2 transient immunity, as documented in ST's official qualification reports.
