STMicroelectronics VND830LSP

Overview

VND830LSP from STMicroelectronics is a double-channel high-side driver IC designed for automotive and industrial load switching applications where one side of the load connects to ground. It delivers 18 A per channel, features 60 mΩ on-state resistance at 25°C, supports 36 V supply voltage, and integrates open-load detection (on/off-state), short-circuit protection, thermal shutdown with automatic restart, and reverse battery protection. It is commonly used in body control modules to drive lamps, solenoids, and relays.

For engineers reviewing the VND830LSP datasheet, VND830LSP pinout, VND830LSP application, or VND830LSP equivalent, key selection criteria include per-channel current capability (18 A), dual independent status outputs with CMOS-compatible inputs, ISO7637-2 transient immunity, loss-of-ground detection, and PowerSO-10 thermal performance under sustained load conditions.

Technical Context

The VND830LSP implements two independent VIPower™ M0-3 high-side switches with integrated current limiting (18–29 A depending on temperature), thermal foldback, and active overvoltage/undervoltage shutdown (36 V OV, 4 V UV). Each channel includes dedicated open-drain status pins reporting fault conditions including overload, overtemperature, open-load (both states), and supply rail violations.

Its architecture enables direct interfacing with microcontroller GPIOs via CMOS-compatible inputs (VIH = 3.25 V, VIL = 1.25 V) and provides diagnostic feedback through separate STATUS1/STATUS2 pins with programmable pull-up. The device uses internal clamping and demagnetization energy handling (up to 52 mJ) to manage inductive kickback without external snubbers in many automotive solenoid applications.

FAQ

What is the maximum continuous output current per channel?

The VND830LSP supports 18 A continuous output current per channel at T_j ≤ 150°C with adequate PCB copper heatsinking (6 cm² Cu per island). Current derating applies above 125°C case temperature, and thermal shutdown activates at 150–200°C junction temperature to protect against sustained overload.

How does the off-state open-load detection work?

In off-state, the device monitors output voltage relative to VCC. If the output rises above 1.5–3.5 V (typ. 2.5 V) while INPUT = 0 V, it detects a short-to-VCC condition and asserts STATUSx low. This function requires no external components and operates independently for each channel, enabling early detection of wiring faults before power-up.

Can VND830LSP drive inductive loads without external flyback diodes?

Yes - the VND830LSP integrates an internal VCC-to-output clamp that handles up to 52 mJ of demagnetization energy (at VCC = 13.5 V, I_L = 14 A). This allows safe switching of typical automotive solenoids and relays without external flyback diodes, though external clamping may still be needed for higher-energy inductive loads beyond specification limits.

Is the PowerSO-10 package RoHS and ECOPACK® compliant?

Yes - the PowerSO-10 package used for VND830LSP is certified ECOPACK® and RoHS-compliant (lead-free, halogen-free), meeting automotive environmental standards. Its exposed thermal pad requires solder paste stencil design per ST's AN4050 guidelines to ensure reliable thermal conduction and mechanical attachment during reflow.
