STMicroelectronics VN02H(012Y)

Overview

VN02H(012Y) from STMicroelectronics is a high-side smart power solid-state relay IC built with VIPower technology, designed to drive resistive or inductive loads with one side grounded. It delivers 6 A continuous output current at Tc = 25 °C, features 5 V logic-compatible input, open-drain diagnostic output, thermal and under-voltage shutdown, and 0.4 Ω on-resistance at 3 A - used in automotive body control modules for lamp and solenoid switching.

For engineers reviewing the VN02H(012Y) datasheet, VN02H(012Y) pinout, VN02H(012Y) application, or VN02H(012Y) equivalent, key selection criteria include verified thermal shutdown behavior (140–160 °C), diagnostic status interpretation (open-load/over-temperature), load-dump immunity per ISO TR/17631 Level III, and PENTAWATT in-line package compatibility with PCB layout constraints.

Technical Context

The VN02H(012Y) integrates a high-side Power MOSFET with embedded protection logic, current sensing, and open-drain status output. Its internal thermal shutdown activates at ≥140 °C junction temperature and resets at ≈125 °C, enabling automatic recovery after fault clearance. The device clamps V_DS to 36 V above rated supply and withstands load dump per ISO TR/17631 Pulse 5 Level III.

Input logic thresholds are defined by V_IL ≤ 0.8 V (low), V_IH ≥ 2 V (high) with 0.5 V hysteresis; the status pin outputs low (<0.4 V at 1.6 mA) during open-load or over-temperature conditions. Under-voltage shutdown triggers between 2.5–5 V V_CC, preventing unreliable operation during brownout.

FAQ

What is the function of the STATUS pin on VN02H(012Y)?

The STATUS pin is an open-drain output that pulls low (<0.4 V at 1.6 mA) to indicate either open-load (no connected load) or over-temperature conditions. It remains high during normal operation and under-voltage shutdown. An external pull-up resistor to V_CC is mandatory for proper logic-level interpretation by the host controller.

Can VN02H(012Y) be used in 12 V and 24 V automotive systems?

Yes - VN02H(012Y) operates across 9–36 V V_CC, covering nominal 12 V and 24 V battery ranges. It meets ISO TR/17631 Pulse 5 Level III load-dump immunity and supports reverse-battery protection up to −26 V using an external Schottky diode on pin 1, as documented in the application circuit.

How does thermal shutdown behave during sustained overload?

When junction temperature reaches 140–160 °C, the device turns off the output and holds it off until temperature drops to 125–145 °C, then automatically resumes operation. This hysteresis prevents oscillation near trip point and allows safe recovery without MCU intervention after fault removal.

Is VN02H(012Y) pin-compatible with other PENTAWATT variants like VN02H(011Y)?

No - VN02H(012Y) uses the PENTAWATT in-line (P010D) package, while VN02H(011Y) uses PENTAWATT horizontal (PO1OL1_E). Pin numbering and physical orientation differ; PCB layout and footprint must be matched specifically to P010D mechanical data (page 8 of datasheet), including L2 = 23.05–23.80 mm and L3 = 25.30–26.10 mm.
