STMicroelectronics VN16BSP13TR

Overview

VN16BSP13TR from STMicroelectronics is a high-side smart power solid-state relay IC designed for automotive-grade load switching with one side grounded. It delivers 20 A continuous output current at Tc = 85°C, features 5 V logic-compatible input, integrated thermal shutdown, under-voltage protection, open-drain diagnostic output, and –18 V inductive load demagnetization voltage - used in engine control modules for solenoid actuation.

For engineers reviewing the VN16BSP13TR datasheet, VN16BSP13TR pinout, VN16BSP13TR application, or VN16BSP13TR equivalent, key selection criteria include R_DS(on) ≤ 0.06 Ω, V_BRDSS = 40 V, diagnostic timing (t_pol up to 2500 µs), thermal shutdown threshold (140–180 °C), and PowerSO-10 package compatibility with FR-4 PCB thermal design.

Technical Context

The VN16BSP13TR integrates a VIPower MOSFET with embedded protection logic and diagnostics in a monolithic structure. Its high-side architecture enables direct battery-switching of resistive or inductive loads while maintaining ground-referenced load return. The device implements fast demagnetization via internal negative clamp (–18 V typical) and provides fault discrimination through dual diagnostic delay times (t_povl = 5–10 µs for overtemperature; t_pol = 50–2500 µs for open-load).

Protection functions are hardware-based and self-contained: thermal shutdown triggers at 140–180 °C with 15–50 °C hysteresis, undervoltage lockout activates at 3.5–6 V, and status output reports open-load (on/off), short-to-V_CC, and overtemperature conditions via open-drain logic level.

Key Specifications

Pinout & Package

FAQ

What is the maximum inductive load energy the VN16BSP13TR can safely demagnetize?

The device supports demagnetization of inductive loads up to 1 mH with 20 A current using its –18 V internal clamp. Energy handling is governed by P_dem = 0.5 × L × I² × [(V_CC + V_demag) / V_demag] × f. At 13 V V_CC, 1 mH, and 100 Hz switching, peak dissipation remains within 82 W P_tot limit when mounted with R_thj-case ≤ 1.5 °C/W.

How does the STAT pin differentiate between open-load and overtemperature faults?

The STAT pin uses two distinct timing windows: after input deactivation, a low-to-high transition within 5–10 µs (t_povl) indicates overtemperature, while a transition within 50–2500 µs (t_pol) signals open-load. This allows firmware to distinguish fault types without additional sensors or circuitry.

Can VN16BSP13TR be used with 24 V commercial vehicle systems?

Yes - V_CC rating extends to 26 V, and V_BRDSS = 40 V ensures margin against load-dump transients per ISO 7637-2 Pulse 5a. However, R_DS(on) increases with junction temperature, so derating to ≤15 A is recommended at sustained 24 V operation with ambient >85 °C.

Is external reverse-battery protection mandatory?

A Schottky diode between GND pin and chassis ground is recommended for continuous –26 V reverse battery exposure (per ISO 16750-2). Without it, the device may latch or sustain damage. The diode introduces ~0.3 V offset, raising V_IL/V_IH thresholds and V_USD by that amount unless signal ground is re-referenced per Figure 11.
