STMicroelectronics VN02HSP13TR

Overview

VN02HSP13TR 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 0.4 Ω on-state resistance, 60 V drain-source breakdown voltage, and integrated thermal/under-voltage shutdown-used in automotive body control modules for headlamp and fan control.

For engineers reviewing the VN02HSP13TR datasheet, VN02HSP13TR pinout, VN02HSP13TR application, or VN02HSP13TR equivalent, key selection criteria include logic-level compatibility (5 V input), open-drain diagnostic output behavior, short-circuit response time (1.5–5 ms), junction temperature limits (140–160 °C), and PENTAWATT vertical package thermal resistance (4.4 °C/W).

Technical Context

The VN02HSP13TR integrates a high-side Power MOSFET with protection logic, thermal sensing, and open-drain status output. Its internal clamp limits V_DS to 36 V above which power dissipation rises sharply, triggering thermal shutdown at ≥140 °C and auto-restart at ≤145 °C.

It supports ISO TR/17631 Level III load-dump immunity and includes under-voltage lockout (2.5–5 V) and over-current detection (28 A peak). The diagnostic output signals open-load and over-temperature conditions via voltage thresholds: V_STAT < 0.4 V (low) or clamped at −0.7 to 6 V (open-drain).

FAQ

What is the maximum continuous output current for VN02HSP13TR at 85 °C case temperature?

The VN02HSP13TR supports 6 A continuous output current only at T_c = 25 °C. At 85 °C case temperature, derating applies per thermal resistance (R_thj-case = 4.4 °C/W); maximum sustainable current drops to approximately 3.2 A to maintain T_j ≤ 150 °C, assuming 28 W max power dissipation limit.

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

The STATUS pin pulls low (< 0.4 V) for both open-load and over-temperature faults; distinction requires timing analysis. During startup or after fault clearance, an open-load condition causes immediate low state upon enable, whereas over-temperature results in delayed low assertion after thermal accumulation-verified via truth table and diagnostic timing >100 µs post-switching edge.

Can VN02HSP13TR be used with a 48 V nominal battery system?

No. VN02HSP13TR has absolute maximum V_CC = 60 V for 400 ms pulses, but its operational V_CC range is strictly 9–36 V. In 48 V systems, sustained voltage exceeds 36 V, causing internal clamping, elevated power dissipation, and premature thermal shutdown-even if peak transients remain within spec.

Is external reverse-battery protection mandatory when using VN02HSP13TR in automotive applications?

Yes. The device tolerates only −4 V reverse supply voltage (absolute max). Automotive reverse-battery events reach −26 V; therefore, a Schottky diode between pin 1 (GND) and chassis ground is mandatory per ST's Fig. 3 recommendation to prevent latch-up or permanent damage.
