STMicroelectronics VN06SP

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_DSS, 0.18 Ω R_DS(on) at 1.9 A, 9 A continuous output current at T_c = 85 °C, 5 V logic-compatible input, and integrated open-drain diagnostic output. Used in body control modules for lamp and solenoid driving.

For engineers reviewing the VN06SP datasheet, VN06SP pinout, VN06SP application, or VN06SP equivalent, key selection criteria include thermal shutdown threshold (140 °C), inductive demagnetization clamp (-18 V), under-voltage lockout (5 V), ISO-compliant open-load detection timing (5–10 ms), and load-dump immunity per ISO 7637-2 Pulse 5 Level II.

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 demagnetization clamp actively dissipates inductive energy during turn-off-reducing dissipation by up to 60% versus passive freewheeling. The device implements ISO 16750-2 compliant load-dump immunity without external components at Level II (46.5 V).

Diagnostic functionality includes open-load detection in both ON and OFF states, overtemperature flagging with no delay on fault assertion, and short-to-V_CC reporting-all delivered via a single open-drain STATUS pin with configurable filtering (t_1(on)/t_1(off)/t_2(off) = 1–10 ms). Input hysteresis (0.5 V) ensures noise-immune logic-level interfacing across automotive temperature range (-40 to +150 °C).

FAQ

What is the maximum inductive load energy the VN06SP can safely demagnetize?

The VN06SP achieves safe demagnetization for inductive loads up to 1 mH at 1.9 A, delivering a typical clamp voltage of -18 V. Using the formula P_dem = 0.5 × L_load × I_load² × [(V_CC + V_demag) / V_demag] × f, designers can calculate allowable inductance for given switching frequency and thermal budget-ensuring junction temperature stays below 140 °C.

How does the VN06SP handle reverse battery conditions?

The VN06SP tolerates reverse battery down to -4 V on V_CC but requires external protection for -26 V. Two validated approaches exist: (1) a Schottky diode between GND pin and chassis ground (shifting VIH/VIL thresholds upward by V_f), or (2) separating signal ground from power ground by connecting the MCU reference to pin 6-preserving native logic thresholds and enabling standard diode use.

Can the STATUS pin drive an LED directly without a microcontroller?

Yes-the open-drain STATUS pin supports up to 10 mA sink current and can directly drive a standard LED with series resistor (e.g., 1 kΩ to 5 V). When pulled high externally, it asserts low for open load (ON/OFF), short-to-V_CC, or overtemperature. No external logic is needed for basic fault indication, though timing filters (5–10 ms) apply to open-load events only.

What is the thermal resistance from junction to ambient under standard mounting conditions?

With minimum recommended FR-4 pad size, R_th(j-amb) is 50 °C/W. However, effective thermal performance depends heavily on PCB copper area: doubling the thermal pad area reduces R_th(j-amb) by ~15%, while adding internal ground planes lowers it further. For 9 A continuous operation, maintaining T_c ≤ 85 °C requires ≥ 4 cm² of 2-oz copper connected to the exposed pad.
