STMicroelectronics VN02HSPTR-E

Overview

VN02HSPTR-E from STMicroelectronics is a high-side smart power solid-state relay IC built with VIPower technology, 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-compatible input, integrated thermal and under-voltage shutdown, and open-drain diagnostic output for open-load and over-temperature detection - used in automotive body control modules and industrial load switching.

For engineers reviewing the VN02HSPTR-E datasheet, VN02HSPTR-E pinout, VN02HSPTR-E application, or VN02HSPTR-E equivalent, key selection criteria include its 60 V V_DSS, 0.4 Ω R_DS(on) at 3 A, 140–160 °C thermal shutdown threshold, diagnostic status signaling, and PENTAWATT vertical package compatibility with automotive-grade transient robustness (ISO TR 17631 Level III).

Technical Context

The VN02HSPTR-E integrates a high-side N-channel Power MOSFET with protection logic, current-sensing circuitry, and an open-drain status output. Its internal thermal shutdown activates at ≥140 °C junction temperature and resets at ≈125 °C, enabling autonomous recovery. The device clamps V_CC to 36 V and limits drain-source voltage to 29 V during fault conditions to ensure safe operation under load dump transients.

Input logic thresholds are defined by V_IL ≤ 0.8 V and V_IH ≥ 2 V (internally clamped to 6 V), supporting direct connection to 5 V microcontrollers. The diagnostic output asserts low during open-circuit or over-temperature events, with status validity confirmed >100 µs after switching edges per truth table behavior.

Key Specifications

FAQ

What is the maximum continuous load current supported by VN02HSPTR-E?

The VN02HSPTR-E supports 6 A continuous output current at case temperature T_c = 25 °C. Current capability decreases with rising case temperature due to thermal limits; at T_c = 85 °C, derated current is approximately 3.5 A based on R_thj-case = 4.4 °C/W and T_j(max) = 150 °C. Heatsinking is mandatory for sustained high-current operation.

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

The STATUS pin is open-drain and pulls low for both open-circuit (no load) and over-temperature faults - it does not distinguish between them electrically. Differentiation requires temporal analysis: open-circuit is detected immediately upon turn-on (no current flow), while over-temperature occurs after sustained conduction. System firmware must correlate STATUS state with switching command timing and thermal history.

Can VN02HSPTR-E operate from a 42 V supply in automotive load-dump scenarios?

No - VN02HSPTR-E has absolute maximum V_CC = 60 V for ≤400 ms, but its functional V_CC range is 9–36 V. Above 36 V, the output clamps to 36 V, increasing power dissipation and triggering thermal shutdown. For ISO 7637-2 Pulse 5 (load dump), external clamping (e.g., TVS diode) is required to limit V_CC to ≤36 V during transients.

Is a series resistor required on the INPUT pin when driven from a 5 V microcontroller?

No series resistor is required. The INPUT pin draws only 250–500 µA at 5 V and is internally clamped to 6 V, making it safe for direct connection to standard 5 V CMOS outputs. However, if driving from >6 V sources (e.g., 12 V logic), a current-limiting resistor must be added to keep input current ≤10 mA per datasheet note.
