STMicroelectronics VND92013TR

Overview

VND92013TR from STMicroelectronics is a dual-channel high-side solid-state relay (HSD) built on VIPower M0-3 technology, designed for driving grounded loads in automotive and industrial power distribution systems. It features 16 mΩ R_DS(on) per channel, 35 A continuous output current, 36 V max V_CC, integrated proportional current sense (K ≈ 4400), and comprehensive protection including thermal shutdown (T_TSD = 150–200 °C), overvoltage clamp (41–55 V), and reverse battery protection. It is used in body control modules for headlight and fan control.

For engineers reviewing the VND92013TR datasheet, VND92013TR pinout, VND92013TR application, or VND92013TR equivalent, key selection criteria include per-channel current sensing accuracy (±8% drift over −40 to +150 °C), SO-28 double-island thermal performance (R_thj-amb = 42 °C/W with both channels active), short-circuit robustness (I_LIM = 30–75 A), and ISO 7637-2 pulse immunity (Class C up to Pulse 5).

Technical Context

The VND92013TR integrates two independent high-side power switches with dedicated logic drivers, current-limiting circuitry, and thermal detection per channel. Each channel implements active V_CC clamping, under/overvoltage shutdown (V_USD = 3–5.5 V, V_OV = 36 V), and loss-of-ground detection - all operating without external components.

Its analog current sense outputs deliver I_SENSE = I_OUT/K (K = 3300–6000 depending on I_OUT and T_j), with <500 µs response delay and ±10% full-range ratio drift. Protection states (overtemperature, short-to-GND/V_CC) force output disable and drive sense pins to V_SENSEH = 5.5 V, enabling fault diagnosis via microcontroller ADC.

FAQ

What is the maximum continuous output current per channel?

The VND92013TR supports 35 A continuous output current per channel under specified thermal conditions: mounted on a standard FR-4 board with ≥1 cm² copper connected to all V_CC pins, horizontal orientation, and no forced airflow. Derating applies above 25 °C ambient; full rating requires R_thj-amb ≤ 42 °C/W (both channels active).

How does the current sense output behave during overtemperature shutdown?

During overtemperature shutdown (T_j ≥ T_TSD), the current sense pin (e.g., CURRENT SENSE 1) is actively driven to V_SENSEH = 5.5 V, overriding the normal proportional I_SENSE signal. This provides a clear, unambiguous fault flag readable by a microcontroller ADC without additional logic or comparators.

Can VND92013TR drive inductive loads like solenoids or relays?

Yes - the VND92013TR is qualified for inductive loads with demagnetization energy handling up to 355 mJ (L = 0.25 mH, I_L = 45 A, T_j,start = 150 °C). Its integrated V_CC clamp and fast turn-off voltage slope (dV_OUT/dt(off) ≥ 250 V/ms) suppress flyback spikes, reducing or eliminating need for external freewheeling diodes in many designs.

What is the purpose of the "double island" SO-28 package?

The SO-28 double-island package physically and thermally isolates the two high-side channels - separating V_CC, GND, and output traces into independent copper islands on the die. This prevents thermal crosstalk, enables independent fault management, improves current sharing, and achieves lower effective R_thj-amb (42 °C/W vs. 55 °C/W for single-channel operation) under dual-load conditions.
