STMicroelectronics VN02H(011Y)

Overview

VN02H(011Y) from STMicroelectronics is a high-side smart power solid-state relay IC built with VIPower technology, designed to drive grounded resistive or inductive loads in automotive and industrial control systems. It delivers 6 A continuous output current at Tc = 25 °C, features 0.4 Ω on-state resistance, 60 V drain-source breakdown voltage, and integrated thermal/under-voltage shutdown with open-drain diagnostic output.

For engineers reviewing the VN02H(011Y) datasheet, VN02H(011Y) pinout, VN02H(011Y) application, or VN02H(011Y) equivalent, key selection criteria include logic-level compatibility (VIH = 2 V min), diagnostic status signaling, short-circuit protection timing (tSC = 1.5–5 ms), and PENTAWATT horizontal package thermal performance (Rthj-case = 4.4 °C/W).

Technical Context

The VN02H(011Y) integrates a vertical power MOSFET with embedded protection logic, enabling single-chip high-side switching without external current-sense or thermal monitoring circuitry. Its input accepts 5 V logic levels, while the open-drain STATUS pin reports open-load and over-temperature faults via voltage thresholds (VSTAT < 0.4 V low, VSCL clamped ±0.3–0.7 V).

Protection functions operate autonomously: thermal shutdown triggers at TJ ≥ 140 °C and resets at ~125 °C; under-voltage lockout activates below VUSD = 2.5–5 V; short-circuit response limits energy dissipation via fast turn-off (td(off) ≤ 30 µs) and current slope control ((di/dt)off ≤ 4 A/µs).

FAQ

What is the maximum continuous output current rating for VN02H(011Y) and under what thermal condition?

The VN02H(011Y) is rated for 6 A continuous output current at case temperature (T_c) ≤ 25 °C. This rating assumes proper heatsinking to maintain R_thj-case ≤ 4.4 °C/W; derating is required above 25 °C per the thermal data table (T_j max = 150 °C).

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

The STATUS pin asserts low for both open-load and over-temperature conditions; distinction requires timing analysis. Open-load is detected within 100 µs after turn-on if no current flows; over-temperature causes sustained low output until junction cools to ~125 °C. External logic or microcontroller sampling is needed to differentiate based on duration and context.

Can VN02H(011Y) be used with a 48 V supply rail?

No-V_CC must remain within 9–36 V. At V_CC > 36 V, the output voltage clamps to 36 V, increasing power dissipation and triggering thermal shutdown. For 48 V systems, use a pre-regulator or select a higher-voltage-rated device such as the IPS2050H (80 V).

Is an external flyback diode required when driving inductive loads?

Yes-an external flyback diode is mandatory across the load to clamp inductive kickback. The VN02H(011Y) includes only a limited internal clamp (V_demag = –2 to –7 V), insufficient for typical solenoid or relay coil energy. ST recommends a fast-recovery diode rated ≥1.5× I_OUT and ≥60 V PIV.
