STMicroelectronics VND81013TR

Overview

VND81013TR from STMicroelectronics is a dual-channel high-side driver IC designed for automotive and industrial load switching applications, featuring 160 mΩ R_DS(on) per channel, 3.5 A continuous output current, 36 V supply voltage rating, and integrated open-load detection in both on- and off-states. It operates in VIPower M0-3 technology and is used to drive grounded loads such as solenoids, relays, and lamps in 12 V/24 V vehicle electrical systems.

For engineers reviewing the VND81013TR datasheet, VND81013TR pinout, VND81013TR application, or VND81013TR equivalent, key selection criteria include its dual-channel high-side architecture, CMOS-compatible inputs, open-drain status outputs with diagnostic capability, short-circuit and thermal protection, and ISO7637 transient immunity-critical for under-hood and body-control module designs.

Technical Context

The VND81013TR integrates two independent high-side power switches with dedicated logic inputs (IN1/IN2), status outputs (STATUS1/STATUS2), and shared VCC and GND pins. Each channel features active current limiting (5.5–7.5 A typ.), thermal shutdown at 150–200 °C, and automatic restart after fault clearance.

Its diagnostic architecture supports real-time load monitoring: on-state open-load detection triggers when output current falls below 20–80 mA; off-state detection activates when output voltage exceeds 1.5–3.5 V relative to ground. Status pins provide open-drain feedback synchronized to input transitions with ≤200 µs delay.

FAQ

What is the maximum junction temperature and thermal shutdown behavior of the VND81013TR?

The VND81013TR triggers thermal shutdown at 150–200 °C (typ. 175 °C) and resets at 135 °C, providing 15 °C hysteresis. Its thermal resistance is 15 °C/W (junction-to-lead) and 57–77 °C/W (junction-to-ambient), depending on PCB copper area. This design prevents permanent damage during sustained overload while allowing automatic recovery once temperature drops below reset threshold.

How does the VND81013TR detect open loads in the off-state?

In the off-state, the VND81013TR applies a small test current through an internal path and monitors output voltage. If V_OUT rises above 1.5–3.5 V (depending on temperature), it indicates an open circuit (e.g., broken wire or disconnected load). This condition pulls the corresponding STATUS pin low, enabling immediate MCU detection without external components.

Can the VND81013TR drive inductive loads like solenoids or relays directly?

Yes-the VND81013TR is explicitly designed for inductive loads. Its integrated V_demag clamp (V_CC − 41 to V_CC − 55 V) safely dissipates demagnetization energy during turn-off. For a 13.5 V system, this provides ≥27 V reverse voltage margin, eliminating the need for external flyback diodes in most automotive solenoid and relay applications.

Is the VND81013TR still in active production, and what is its packaging format?

The VND81013TR is supplied in tape-and-reel format (suffix "TR") per SO-16 package, with 2,500 units per reel. While STMicroelectronics lists VND810 as "Obsolete Product(s)" in newer documentation, the VND81013TR variant remains actively distributed by authorized channels and supported by Aetrix Electronics with full traceability and extended lifecycle management.
