STMicroelectronics VND830

Overview

VND830 from STMicroelectronics is a double-channel high-side driver IC designed for automotive and industrial load control, featuring 60 mΩ R_DS(on) per channel, 6 A continuous output current, and 36 V maximum supply voltage. It integrates open-load detection (on/off-state), short-circuit protection, thermal shutdown with automatic restart, undervoltage/overvoltage shutdown, and loss-of-ground protection - deployed in engine control modules, body electronics, and smart power distribution units.

For engineers reviewing the VND830 datasheet, VND830 pinout, VND830 application, or VND830 equivalent, key selection considerations include its dual-channel high-side switching architecture, CMOS-compatible inputs, open-drain status outputs with diagnostic capability, and ISO7637-2 transient immunity up to ±100 V - critical for robust 12 V/24 V vehicle electrical systems.

Technical Context

The VND830 implements two independent VIPower M0-3 high-side switches with integrated current limiting (6–15 A depending on V_CC and case temperature), active overtemperature shutdown at 150–200 °C, and hysteresis-based reset at 135 °C. Each channel features dedicated status pins with open-drain output and internal clamping (6–8 V).

It supports diagnostic functions including on-state open-load detection (50–200 mA threshold) and off-state open-load detection (1.5–3.5 V threshold), both with defined delay times (200 µs and 1000 µs respectively), enabling reliable fault reporting to microcontrollers without external sensing components.

The following parts are listed as comparable options for similar high-side driver applications.

Compared with VND830, STSPIN840 offers higher integration for motor control but sacrifices dual-channel simplicity and automotive-grade fault coverage; TPS27082L trades diagnostic completeness for compactness and faster switching - making VND830 optimal for cost-sensitive, safety-aware dual-load applications requiring full self-diagnostics.

FAQ

What is the maximum operating temperature and thermal derating behavior of the VND830?

The VND830 features internal thermal shutdown at 150–200 °C (typical 175 °C) with hysteresis of 7–15 °C and reset at 135 °C. Its R_DS(on) increases with junction temperature - rising from 60 mΩ at 25 °C to ~120 mΩ at 150 °C - requiring PCB copper area ≥6 cm² for full 6 A rating at ambient 85 °C per ST's thermal data (Table 4).

How does the VND830 detect open-load conditions in the off-state?

The VND830 applies a weak internal current source to the output pin when the channel is off; if the output voltage rises above 1.5–3.5 V (depending on temperature), it indicates an open load. This is reported within 1000 µs via the corresponding STATUS pin going low - enabling detection of broken wires or disconnected actuators without external components.

Can the VND830 drive inductive loads such as solenoids or relays safely?

Yes - the VND830 includes active demagnetization clamping (V_demag = V_CC − 41 to V_CC − 55 V) and supports maximum turn-off energy of 102 mJ (L = 1.8 mH, V_bat = 13.5 V). Its current-limiting and thermal protection prevent latch-up during inductive kickback, provided PCB layout follows ST's SO-16L thermal guidelines (Fig 27–29).

Is the VND830 still in active production or marked obsolete?

The VND830 is marked "Obsolete Product(s)" in ST's official documentation (Rev 3, Dec 2008), but remains available through authorized distributors and Aetrix Electronics' legacy component program with full traceability, extended lifecycle support, and guaranteed supply for existing designs undergoing long-term production or maintenance cycles.
