STMicroelectronics VN06(011Y)

Overview

VN06SP from STMicroelectronics is a high-side smart power solid-state relay in PowerSO-10™ package, designed for automotive-grade resistive and inductive load switching with one side grounded. It features 60 V V_DS(off), 0.18 Ω R_DS(on) at 1.9 A, 9 A max continuous output current at T_c = 85 °C, integrated thermal shutdown, under-voltage protection, and open-drain diagnostic output. Used in body control modules for headlight, fan, and heater control.

For engineers reviewing the VN06SP datasheet, VN06SP pinout, VN06SP application, or VN06SP equivalent, key selection criteria include ISO-compliant nominal current (1.9 A), -18 V inductive demagnetization clamp, 5 V logic-compatible input, diagnostic filtering timing (t_1(on)/t_1(off) = 1–10 ms), and load-dump pulse 5 level II immunity without external components.

Technical Context

The VN06SP integrates a VIPower MOSFET with embedded protection logic and diagnostics. Its high-side architecture enables direct battery-switching of grounded loads, while the -18 V V_demag clamping ensures fast inductive energy dissipation without external flyback diodes. The device implements ISO-defined open-load detection with dual-stage filtering (5 ms activation/deactivation delay) and fault-specific status timing (t_povl = 5–10 μs, t_pol = 50–700 μs).

Thermal protection activates at 140 °C junction temperature and resets at 125 °C, enabling automatic recovery after overtemperature events. Under-voltage lockout triggers at 5 V V_USD, and short-circuit current limiting delivers 60 A peak I_OV with 1.4 A average I_AV in sustained fault conditions at T_c = 85 °C.

FAQ

What is the maximum inductive load energy the VN06SP can safely dissipate during turn-off?

The VN06SP achieves safe inductive turn-off via its -18 V V_demag clamp, which reduces dissipated energy per cycle to P_dem = 0.5 × L_load × I_load² × [(V_CC + V_demag) / V_demag] × f. For a 1 mH load at 1.9 A and 100 Hz switching, dissipation remains below 1.2 W-well within the 27 W thermal budget at T_c = 85 °C.

Does the VN06SP require an external pull-up resistor on the STAT pin?

Yes-the STAT pin is an open-drain output and requires an external pull-up resistor (typically 4.7 kΩ to V_CC) to generate valid logic-high signals. Without it, the diagnostic output cannot indicate open-load or overtemperature faults, compromising ISO-compliant fault reporting in automotive ECUs.

Can the VN06SP drive loads directly from a 24 V truck battery system?

Yes-the VN06SP supports V_CC up to 26 V and is qualified for 24 V commercial vehicle applications. Its 60 V V_DS(off) and ISO 7637-2 Pulse 5 Level III compatibility (with 150 Ω + 1000 μF filter) ensure robust operation during cranking and load-dump events in heavy-duty environments.

How does the VN06SP differentiate between open-load and overtemperature faults on the STAT pin?

The STAT pin asserts low for both conditions, but timing behavior differs: overtemperature causes immediate low transition (<1 μs), while open-load detection includes a 5 ms filtering delay (t_1(on)). Additionally, after fault clearance, overtemperature recovery has no delay, whereas open-load recovery requires t_1(off) = 1–10 ms-enabling firmware to distinguish fault types using edge timing analysis.
