STMicroelectronics VN02H-11-E

Overview

VN02H-11-E from STMicroelectronics is a high-side smart power solid-state relay IC built with VIPower technology, designed for driving grounded resistive or inductive loads in automotive and industrial control systems. It delivers 6 A continuous output current at Tc = 25 °C, features 5 V logic-compatible input, integrated thermal shutdown (140–160 °C), under-voltage lockout (2.5–5 V), and open-drain diagnostic output for open-load and over-temperature detection.

For engineers reviewing the VN02H-11-E datasheet, VN02H-11-E pinout, VN02H-11-E application, or VN02H-11-E equivalent, key selection criteria include its 0.4 Ω RDS(on) at 3 A, 60 V V(BR)DSS rating, 5–36 V VCC operating range, diagnostic status signaling, and PENTAWATT vertical package compatibility with automotive load-dump immunity per ISO TR/17631 Level III.

Technical Context

The VN02H-11-E integrates a high-side Power MOSFET with protection logic, thermal sensing, and diagnostic circuitry in a monolithic VIPower structure. Its input stage accepts 5 V TTL/CMOS logic levels (VIH ≥ 2 V, VIL ≤ 0.8 V), while the open-drain STATUS pin reports fault conditions via voltage thresholds: low (<0.4 V) for normal operation, high (>100 µs after edge) for open-load or over-temperature.

Protection functions operate autonomously: under-voltage shutdown activates below 2.5 V VCC, thermal shutdown disables the output above 140 °C junction temperature (reset at ~125 °C), and short-circuit response limits IOUT to 28 A peak with 1.5–5 ms switch-off time. Clamp voltage during inductive demagnetization is –4 V typical.

FAQ

What is the maximum continuous output current for VN02H-11-E and under what thermal conditions?

The VN02H-11-E delivers 6 A continuous output current at case temperature (Tc) = 25 °C. Current derating follows Rthj-case = 4.4 °C/W: at Tc = 85 °C, maximum continuous current drops to approximately 3.5 A. Junction temperature must remain ≤150 °C for reliable operation.

How does the STATUS pin indicate open-load versus over-temperature faults?

The STATUS pin is open-drain and pulled high externally. It remains low during normal operation. It goes high (>100 µs after switching edge) for both open-load (IOL < 5 mA) and over-temperature (Tj > 140 °C); the two conditions cannot be distinguished electrically by STATUS alone and require system-level context or timing analysis.

Can VN02H-11-E operate directly from a 24 V truck battery without external regulation?

Yes. The VN02H-11-E supports VCC from 5 V to 36 V and includes internal clamping at 36 V. It withstands ISO TR/17631 Level III load-dump pulses (up to ~60 V for 400 ms), making it suitable for direct connection to unregulated 24 V vehicle batteries with appropriate PCB layout and external flyback diode for inductive loads.

Is reverse-battery protection integrated, or does it require external components?

Reverse-battery protection is not integrated. ST recommends adding a Schottky diode between pin 1 (GND) and chassis ground to block –26 V reverse polarity. This introduces a forward voltage shift (~0.3–0.5 V) affecting VIH/VIL thresholds and under-voltage detection, which can be mitigated by referencing the control unit to pin 1 (Fig. 4).
