STMicroelectronics VN02NSP13TR

Overview

VN02NSP13TR from STMicroelectronics is a high-side smart power solid state relay IC designed for driving resistive or inductive loads with one side grounded. It delivers 6 A continuous output current at Tc = 25°C, features 5 V logic-level input compatibility, integrated thermal and under-voltage shutdown, open-drain diagnostic output, and 0.4 Ω typical RDS(on) at 3 A and 25°C. Used in automotive body control modules for headlight or fan control.

For engineers reviewing the VN02NSP13TR datasheet, VN02NSP13TR pinout, VN02NSP13TR application, or VN02NSP13TR equivalent, key selection criteria include its 60 V VDSS rating, thermal shutdown at 140°C, diagnostic status reporting, PENTAWATT package thermal resistance (4.35 °C/W), and compatibility with 5 V microcontroller GPIOs.

Technical Context

The VN02NSP13TR integrates a VIPower high-side MOSFET switch with protection logic and diagnostics in a monolithic silicon structure. Its internal circuitry monitors junction temperature, supply voltage, load current, and open-load condition to autonomously disable the output during fault events including short-circuit, over-temperature (>140°C), and undervoltage (<6.5 V).

Diagnostic feedback is provided via an open-drain STATUS pin that pulls low for open-circuit (no load) or over-temperature conditions, and remains high during normal operation or under-voltage shutdown. Input logic thresholds are hysteresis-enabled (0.5 V), with VIH clamped at 6 V and VIL ≤ 0.8 V, ensuring robust noise immunity in automotive environments.

FAQ

What is the maximum continuous output current for VN02NSP13TR at 85°C case temperature?

At Tc = 85°C, the VN02NSP13TR delivers approximately 2.5 A continuous output current, as shown in Figure 10 (Output current derating). This derating ensures safe operation within thermal limits without external forced cooling, based on its 4.35 °C/W junction-to-case thermal resistance and 140°C thermal shutdown threshold.

Can VN02NSP13TR drive inductive loads without external components?

No-VN02NSP13TR requires an external flyback diode across inductive loads to clamp back-EMF during turn-off. The device does not integrate freewheeling capability. ST recommends a Schottky diode rated for ≥6 A and ≥60 V reverse voltage, placed between OUTPUT and GND, as shown in application schematics (Figure 12 and 13).

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

The STATUS pin asserts low for both open-load and over-temperature faults, with identical electrical behavior. Differentiation requires system-level timing analysis: open-load is detected immediately after turn-on (within 100 µs), while over-temperature occurs after sustained overload. ST's application note AN2499 details software-based discrimination using pulse-width or thermal history.

Is VN02NSP13TR compliant with automotive AEC-Q100 qualification?

Yes-VN02NSP13TR is qualified per AEC-Q100 Grade 1 (−40°C to +125°C ambient), verified through stress testing including HTOL, TC, and ESD. The PENTAWATT package carries ECOPACK® lead-free certification, and full qualification data is documented in ST's official AEC-Q100 report for the VN02N series (Rev. 2, 2008).
