STMicroelectronics VND5E004C30TR-E

Overview

VND5E004C30TR-E from STMicroelectronics is a dual-channel 4 mΩ high-side driver IC for automotive 12 V grounded loads, featuring proportional analog current sense per channel (K₀ = 12130 typ.), AEC-Q100 qualification, and integrated diagnostics including off-state open-load, short-to-V_CC, and thermal shutdown with auto-restart. It operates from 4.5–28 V, delivers up to 90 A peak current per channel, and supports 3 V/5 V CMOS-compatible microcontroller interfaces.

For engineers reviewing the VND5E004C30TR-E datasheet, VND5E004C30TR-E pinout, VND5E004C30TR-E application, or VND5E004C30TR-E equivalent, key selection criteria include on-state resistance (3–6 mΩ over temperature), diagnostic enable (DE) timing (50–600 µs response), current sense accuracy (±14% drift over -40°C to 150°C), and MultiPowerSO-30 thermal performance (R_thj-case = 0.35 °C/W).

Technical Context

This device implements ST's VIPower® M0-5 technology to integrate two independent high-side power switches with active current limiting, inrush management, and overvoltage clamping (41–52 V). Each channel includes dedicated analog current sense (CS1/CS2) with programmable gain and fault reporting via voltage drop limitation (25 mV at 1 A) and thermal shutdown (150–200 °C trip).

The DE pin enables global diagnostic activation; when pulled low, it disables current sensing to share external sense resistors across multiple devices. Protection logic combines undervoltage lockout (4.5 V threshold), reverse battery tolerance (-16 V), and loss-of-ground/V_CC detection - all validated per ISO 7637-2 and AEC-Q100 Grade 0 requirements.

FAQ

What is the maximum allowable transient voltage on VCC?

The VND5E004C30TR-E supports up to 41 V on VCC for durations ≤400 ms, meeting ISO 7637-2 Pulse 5a requirements for automotive load-dump events. This eliminates the need for external TVS diodes in most 12 V ECU designs, provided PCB layout maintains low inductance between VCC pin and bulk capacitance.

How does the DE pin affect current sense functionality?

Pulling DE low disables all analog current sense outputs (CS1/CS2) and associated diagnostics (open-load, overload indication), allowing shared use of a single external sense resistor across multiple VND5E004C30TR-E devices. When DE is high, each channel provides independent proportional I_SENSE with 50–600 µs response latency depending on fault type.

Can this device drive inductive loads like fuel injectors without external flyback protection?

Yes - the VND5E004C30TR-E integrates active V_CC clamping and demagnetization energy handling (600 mJ max per pulse), enabling direct driving of inductive loads such as fuel injectors and solenoids. Its turn-off voltage clamp (V_DEMAG = V_CC−32 V) limits inductive kickback without requiring external diodes in typical 12 V applications.

What is the thermal resistance from junction to case, and how should it be used in layout design?

R_thj-case is 0.35 °C/W per channel (with one channel ON), measured with the exposed die pad soldered to ≥58 mm × 58 mm copper area (2 mm PCB thickness, 35 µm Cu). To achieve this rating, the MultiPowerSO-30 thermal pad must be fully connected to an internal ground plane via ≥6 thermal vias (0.3 mm diameter, 0.8 mm pitch) beneath the package.
